A primary precept of the universe dictates that you’ll misplace your keys solely if you’re already late. If this occurs extra typically than you’d like, a Bluetooth tracker might help. Connect one to your keys or stuff one in your bag (additionally they work nicely with wallets and jackets) and when you’ll be able to’t observe one thing down, your telephone will make the tag ring till you discover it. These helpful fobs also can ship alerts if you’re about to go away them behind and might faucet into huge networks of different smartphones to anonymously find misplaced gadgets out on the imply streets. I examined choices from all the key producers to search out the most effective Bluetooth trackers for all kinds of wants.
Editor’s observe 6/17/2024: Two of the trackers we suggest come from Tile, which was just lately the sufferer of a hacker who gained entry to buyer knowledge together with names, bodily addresses and telephone numbers. We’re always re-evaluating our prime picks and can take this under consideration in subsequent story updates.
Additionally, we just lately acquired our arms on the Pebblebee Clip and Chipolo’s One Level trackers, each of which depend on Google’s new Discover My System community. We’re within the strategy of testing them and can replace this information as soon as we’ve completed.
What to search for in a Bluetooth monitoring gadget
Bluetooth trackers are small discs or playing cards that depend on short-range, low-energy wi-fi alerts to speak together with your smartphone. Connect one to your stuff and, if it’s in vary, your telephone can “ring” the chip so you will discover it. These monitoring units supply different options like separation alerts to let you know if you’ve left a tagged merchandise behind, or the place a misplaced merchandise was final detected. Some may even faucet into a bigger community of smartphones to trace down your gadget if you’re out of vary. Relying on what you need the tracker to do, there are a number of specs to search for when deciding which to get.
System compatibility
Like most issues from the parents in Cupertino, AirTags solely work with merchandise within the Apple ecosystem. The corporate has opened up entry to its Discover My community to third-party producers, together with Chipolo and Pebblebee. These finders work with Apple’s massive monitoring community, however solely pair with Apple units. Chipolo’s basic trackers will work with both Android or Apple units, as will Tile trackers. Samsung’s newest fob, the Galaxy SmartTag2, solely works with Samsung telephones, however new tags from Chipolo and Pebblebee that depend on Google’s new Discover My System community will work with any Android telephone (working Android 9 or later).
Discovering community
Crowd-sourced discovering capabilities are what make headlines, with tales about recovering stolen tools or monitoring misplaced baggage throughout the globe. Utilizing nameless alerts that ping different individuals’s units, these Bluetooth monitoring units can probably let you know the place a tagged merchandise is, even when your smartphone is out of Bluetooth vary. Apple’s Discover My community is the biggest, with over a billion iPhones in service all working Apple’s Discover My app by default. So until an iPhone consumer opts out, their telephone silently acts as a location detector for any close by AirTags.
Now that Google’s Discover My System community is up and working, it’s a detailed second for the biggest within the US. Like Apple, Android customers are routinely a part of the community, however can opt-out by choosing the Google providers possibility of their telephone’s Settings app and toggling the choice within the Discover My System menu. Samsung’s SmartTag 2 and associated community additionally defaults to an opt-in standing for locating tags and different units.
Tile affords a big discovering grid, with each smartphone that runs the Tile app performing as incognito locators. After Life360 acquired Tile, the 47 million customers of that app had been added to the 50 million current Tile customers, creating a large community.
In our exams, AirTags provided practically real-time location knowledge and had been quickest to search out gadgets deserted in spots round Albuquerque, together with a bar, bookstore and low store in Nob Hill, together with varied outside hangouts on UNM’s campus. Tile trackers and Samsung’s SmartTags had been in a position to find our misplaced gadgets more often than not, although not with the identical pin-point accuracy as AirTags. Chipolo’s Spot trackers function on the identical Discover My community and carry out on par with the AirTags.
Chipolo’s basic trackers, alternatively, don’t have a lot of a crowd-sourced community to talk of. But as we used the trackers, the scale of the discovering community began to really feel much less vital within the face of typical, on a regular basis use instances. It was their capacity to out-perform in each different manner that boosted Chipolo’s basic trackers to the highest of our checklist.
Separation alerts
Right here’s the place a tracker’s day-to-day utility actually shines. A separation alert lets you already know if you’ve traveled too far out of your tagged gadgets, which is beneficial if you wish to ensure your laptop computer bag, or jacket or umbrella at all times comes with you if you go away the home.
These notifications work if you’re out and about too. In the event you’ve acquired a Bluetooth monitoring gadget in your pockets and stroll out of a restaurant with out it, the separation alert ought to kick in, leading to fewer misplaced gadgets. This function additionally tells you the place your tagged merchandise and telephone had been final paired, permitting you to retrace your steps in the event you occur to overlook the alert.
Every tracker handles left-behind gadgets in another way. Each AirTags and Chipolo embody the function by default. Tile trackers require a yearly subscription to allow the alerts (at present $30 per yr). Each AirTags and Tiles permit you to flip off separation alerts at sure areas, which means you’ll be able to set your house as a “secure” place the place gadgets may be left behind, however alerts will nonetheless set off elsewhere. Chipolo doesn’t supply secure areas, however you’ll be able to toggle out-of-range alerts on a per-item foundation.
In our exams, the Chipolo despatched an alert after we acquired between 250 and 450 ft away from our tagged merchandise. AirTags alerted us between the 600- and 1,400-foot mark. And Tiles despatched a notification after about a mean of 1,500 ft. Tile notifications weren’t constant on an iPhone, however labored nicely when working with an Android telephone.
Connectivity, quantity and design
The function you could use most frequently is the important thing finder operate, which makes the tracker ring if you hit a button within the app. The SmartTag2, Tile, Chipolo basic and Pebblebee trackers utilizing the Pebblebee app can even allow you to double click on the gadget itself to make your telephone ring. AirTags and any third celebration tags working on both the Discover My (Apple) or Discover My System (Google) app don’t supply this function.
The amount of the Bluetooth monitoring gadget might decide whether or not you will discover an merchandise buried in your sofa cushions or in a loud room. AirTags have a popularity for being on the quiet facet, and that aligned with what we noticed (measuring roughly 65 decibels). Chipolo’s keychain-style tags, each the Apple-only model and the device-agnostic model, and the Tile Slim pockets tracker had been the loudest, measuring between 83 and 85 decibels.
Design will decide what you’ll be able to connect the tracker to. AirTags are small, clean discs that may’t be secured to something with out equipment, that are quite a few, however that’s an extra value to think about. Each Chipolo and Tile supply trackers with holes that simply connect to your key ring, and each corporations additionally supply card-shaped variations designed to slot in your pockets. Tile additionally makes Tile Stickers, that are even smaller trackers that adhere to issues like your TV’s distant.
Batteries are replaceable for AirTags, Tile Professional and Chipolo One; the primary two have a one-year battery life and the Chipolo can go as much as two years. Tile Mate and all card-shaped trackers don’t have replaceable batteries, which implies you’ll have to switch your entire unit every time it dies. Pebblebee trackers are rechargeable and are available in each a key fob and pockets selection.
Stalking and stealing
AirTags have gotten numerous consideration and even prompted some lawsuits for Apple resulting from dangerous actors planting them on individuals to be able to stalk them. Whereas this reality might not affect your shopping for determination, any dialogue of Bluetooth trackers ought to observe what steps Apple, Google and Tile have taken to deal with the problem. Final yr, all the key gamers within the Bluetooth tracker enterprise teamed as much as fight misuse and standardize how unauthorized monitoring detection and alerts work for iOS and Android.
Lately, Tile launched a function referred to as Anti-Theft Mode, which allows you to render one in all its trackers undetectable by others. Meaning if somebody steals your tagged merchandise, they received’t be capable to use the anti-stalking options to search out its exact location and disable the tracker. In fact, that probably makes a Tile simpler to make use of as a stalking gadget, so to be able to allow the function, it’s important to confirm your ID and conform to a $1 million penalty for misuse.
Normally, a Bluetooth tracker might or is probably not the most suitable choice for combating theft. Anecdotal tales abound by which individuals have recovered stolen items utilizing a tracker — however different tales are extra cautionary. Neither Apple nor Google promotes its trackers or discovering networks as a method to take care of theft. GPS trackers, alternatively, are usually marketed for simply that goal.
How we examined
Earlier than deciding on which trackers to check, we researched the sphere, taking a look at consumer opinions on Amazon, Greatest Purchase and different retailers, together with discussions on websites like Reddit. We additionally checked out what different publications needed to say on the matter earlier than narrowing down our picks to Apple AirTag, Tile and Chipolo trackers. When Samsung’s SmartTag 2 got here out in October of 2023, we added that to our testing, together with Pebblebee’s rechargeable Chip tracker.
Right here’s the total checklist of each tracker we examined:
After buying the trackers, I examined every one over the course of some weeks utilizing each an iPhone 11 and a Samsung Galaxy S22 Extremely. I recreated possible consumer experiences, resembling dropping and leaving gadgets behind at house and out within the metropolis. I planted trackers at totally different spots close to downtown Albuquerque, largely concentrated in and across the College of New Mexico and the encircling neighborhood of Nob Hill. Every take a look at was carried out a number of instances, each whereas strolling and driving and I used the measure distance function on Google Maps to trace footage for alerts. I paid consideration to how straightforward the app was to make use of, how dependable the phone-to-tracker connection was and every other perks and downsides that got here up throughout common use.

Format: Disc with gap | Compatibility: Android and iPhone | Water resistance: IPX5 (splash resistant) | Battery life: 2 years | Replaceable battery: Sure | Distance for left-behind alerts: 350 ft. | Telephone finder operate: Sure
Arms-on testing is nice at smashing assumptions, and that’s what occurred with the Chipolo One. This tracker’s crowd-sourced discovering community can’t evaluate with Apple’s AirTag or Tile. In truth, after I left the Chipolo for twenty-four hours simply exterior the busy pupil union at UNM, I used to be by no means alerted {that a} member of the Chipolo neighborhood had detected my merchandise. However as I used it and pictured how most individuals would use a tracker every day, the gadget proved its price and earned its spot on my keyring.
The One is a small and colourful plastic disc with a gap. It really works with each Apple and Android units and requires an app which is easy to make use of and simply pairs new trackers. The app and monitoring expertise on an iPhone and a Galaxy telephone had been practically similar, working equally nicely on each platforms. It rang the loudest of all of the trackers, so misplaced gadgets had been shortly discovered round the home. In contrast to different trackers, there was by no means a delay between urgent the Ring to Discover button and listening to the trill. The ring delay for AirTag was by no means quite a lot of seconds and Tiles would typically join and ring after not more than ten seconds. Whereas that’s not a deal-breaking delay, it might add to the stress of dashing out the door.
The place the Chipolo One really set itself aside was with its separation alerts. I’d solely get a half to 2 blocks away (or a mean of 350 ft) earlier than getting an alert asking if I’d forgotten an merchandise. Neither AirTag nor Tile ever beat Chipolo to the punch. The alerts had been constant whether or not I used to be forgetting an merchandise at house, at a espresso store, or inside my automobile.
So far as dropping stuff out within the wild, it’s going to get you again to the spot the place your telephone and tracker had been final paired. Meaning in the event you miss an alert or don’t have them turned on, Chipolo offers you instructions (through your maps app) and take you proper to the place you left your merchandise. In a single take a look at, I had a good friend disguise the tracker close by after I wasn’t wanting. I left the realm and returned hours later, utilizing the final location info to steer me inside a number of ft of the tracker’s exact location. Ringing the tracker then made it straightforward to search out. In fact, if somebody walks off together with your tracked merchandise, the Chipolo can be more durable pressed that can assist you out.
In the event you’re involved about misplaced baggage if you journey or in the event you fear you could lose issues on trains or buses, this isn’t the tracker for you due to its a lot smaller discovering community. However in the event you’re on the lookout for a lifeless easy method to discover your keys and ensure your jacket leaves the bar if you do, the Chipolo One is difficult to beat.
Chipolo can even permit you to use Alexa to assist discover your keys. You may must allow the Chipolo ability within the Alexa app and join your Chipolo account. Relying in your good house assistant to search out your misplaced keys might make an on-time departure even simpler.

Format: Clean disc | Compatibility: iPhone | Water resistance: IP67 (water and dust-resistant) | Battery life: 1 yr | Replaceable battery: Sure | Distance for left-behind alerts: 1,200 ft | Telephone finder operate: No
AirTags work with iOS’ Discover My app, in order that they don’t require any further downloads. In the event you’ve used the Discover My app earlier than, you’ll possible perceive how this works. These are the quietest of the trackers we examined and every time you press the Play Sound button, the tags solely ring for seven seconds. You’ll must hold urgent in the event you don’t discover your merchandise instantly and AirTags can’t be used to ring your telephone.
As for separation alerts, AirTags had been constant, at all times delivering a “left behind” alert after I traveled about 1,200 ft away, or about three sq. blocks, with out an merchandise. You may flip off separation alerts for any given tracker, in addition to designate sure areas, resembling your house or office, as exceptions for the notifications.
One function that AirTags have that no different tag affords is the flexibility to faucet into the ultra-wideband (UWB) wi-fi protocol. This lets you play a enjoyable recreation of cold and hot with an merchandise when it’s inside about 25 ft of your iPhone. Directional arrows and a diminishing distance meter in your iPhone’s display screen level you to an merchandise with out having to ring it. This labored reliably about 75 p.c of the time in my exams; typically it was simply simpler to ring the merchandise when the directional discovering couldn’t hold a lock on the tracker.
UWB is supported by iPhone fashions 11 and later and whereas newer Galaxy and Pixel telephones additionally assist UWB, no Android-compatible tracker has but been launched. In 2021, Tile introduced one that may, however has since missed its promised launch window of “early 2022.”
AirTag’s capacity to find a misplaced merchandise out within the metropolis is nearly eerie. I had somebody (who was not carrying an iPhone) take my bike with a tracker hidden below the seat to a location a bit of over a half mile away. I set out a couple of minutes later and toggled on Notify When Discovered within the Discover My app. Inside three minutes, I obtained a notification that the bike had been “seen” close to an tackle. Tapping on Instructions navigates to Apple Maps, which took me to a spot about 30 ft from the bike. Had it been obscured from view, I might have then used the Discover Close by button to activate the UWB finding options. Ringing the tag was too quiet to listen to on the sidewalk.
If you need the identical scary-precise neighborhood discovering options, however with a louder ring and a gap within the tracker, the Chipolo One Spot is a strong possibility. It doesn’t supply UWB capabilities, nevertheless, and the separation alerts are the identical as with AirTags (letting you get 1,200 ft away earlier than a ping, versus a mean of 350 ft with our prime rec, Chipolo One basic).
Or, for a chargeable possibility, the Pebblebee Clip is an efficient AirTag different. True, you’ll be able to swap out the battery in Apple’s discs, however charging your tracker through USB-C each few months is perhaps simpler. The Pebblebee works with Apple’s Discover My community and has the identical setup as an AirTag. In my exams, it was noticed simply as shortly as Apple’s tracker, and the left-behind alerts went off about the identical distance away.
However the Pebblebee has a number of benefits over AirTags: The black disk has a built-in steel attachment level and features a small carabiner clip, so for many conditions, you received’t want an extra accent. The Pebblebee is way louder than Apple’s tracker, too. I additionally like that if you ping it from the app, it continues ringing till you hit cease as an alternative of going silent after seven seconds. Pebblebee makes a chargeable pockets tracker as nicely, which can be simpler to slip in a billfold than the rounded AirTag. One phrase of warning, nevertheless: In the event you’re going to make use of it with Discover My, don’t set it up with Pebblebee’s personal app beforehand. In the event you do, you’ll must do a manufacturing facility reset earlier than it’ll work with Apple’s app.

Format: Rectangular fob with gap | Compatibility: Android and iPhone | Water resistance: As much as 3 ft | Battery life: 1 yr | Replaceable battery: Sure | Distance for left-behind alerts: 1,500 (requires subscription) | Telephone finder operate: Sure
Tile will work with both Android or Apple units, however the expertise is significantly better on Android. Sure connectivity points and a scarcity of alerts that plagued the iPhone expertise didn’t present up in exams with the Galaxy telephone. One caveat to notice is that Tile requires a subscription to allow separation alerts. Tile Premium goes for $3 monthly or $30 per yr and contains location historical past and merchandise reimbursement of as much as $100 on gadgets that you simply register with the corporate, they’ll additionally ship out a recent battery yearly. Tile stands out as the one tracker firm providing reimbursement — even with out a subscription, they’ll pay out as much as $25 for gadgets that you simply register with them.
The Tile Professional is a key-fob formed gadget with a steel keychain gap that feels sturdy. The Professional’s ring was just some decibels quieter than the Tile Mate (78 versus 82 decibels), however the connectivity vary was higher with the Professional, and it was extra correct in finder community exams. On prime of that, that is the one present Tile gadget with a replaceable battery, which lasts about one yr.
For the lost-item exams, I had a good friend take the Professional to random areas. After turning on the Notify When Discovered function, an alert would arrive between 5 and ten minutes later saying my misplaced merchandise was “discovered by the neighborhood.” The map particulars had been usually correct inside about 100 ft or so, although it often thought the Tile was at a enterprise subsequent door to the place it truly was. With out the UWB function, precision discovering of an merchandise was trickier. In a single take a look at, the tracker ended up in a loud pub. Whereas the instructions pointed me to the correct location, it might have been troublesome to search out the merchandise if I hadn’t noticed my good friend, because the ring operate was ineffective among the many din.

Nothing can beat the vastness of Apple’s Discover My community, because it depends on each close by iPhone to assist find AirTags. The variety of Samsung telephones within the US could also be smaller than the variety of Apple handsets on the market, nevertheless it’s nonetheless important. The brand new SmartTag 2 depends on these telephones to supply a discovering community that won’t greatest Apple’s, however is bigger than the rest on the market for Android in the meanwhile. In fact, as soon as Google unleashes its expanded Discover My System community, all the things will change.
The SmartTag 2 solely works with Samsung units and after testing one out with a Galaxy S23, I used to be impressed how shortly it was capable of finding tagged gadgets out within the wild, although the precision didn’t fairly match that of Apple. Of all of the trackers I’ve tried, I just like the design of the SmartTag the most effective. It’s an rectangular fob with an enormous gap for attaching on to your keys, or you should purchase the non-obligatory silicone case and ring Samsung affords. Its quantity is louder than the AirTag and the Tile Professional, however not as loud as both the Chipolo One or the Pebblebee Clip. You may also change the tag’s ringtone or double squeeze it to ring your handset, each issues that you could’t do with AirTags.
Setup is easy as nicely: when you take away the plastic pull tab, your telephone senses the tracker and walks you thru the usual permissions (location providers, notifications) and warnings (don’t use the tracker on individuals). The companion app, SmartThings Discover, tracks your Samsung units and the SmartTag with an intuitive and clear Google Maps-based interface.
As for the way the tag works in follow, I discovered the left behind alerts triggered reliably after I acquired about three blocks (1,200 ft or so) away when strolling and about eight blocks away when driving. That’s far longer than Chipolo’s alerts, a bit of longer than Apple’s notifications and about on par with Tile’s left-behind function.
When the tag is out of vary and also you allow Misplaced Mode, you’ll get an alert when it’s noticed by one other Samsung telephone. The tag additionally makes use of NFC to show your contact information and a customized observe to anybody who finds the tracker, whatever the model of smartphone they carry. In fact, whoever finds it might must know to carry it to the again of their telephone to get the message, and it was more durable to set off with my iPhone when the tag was within the silicone holder.
To check the discovering community, I requested a good friend (with out a telephone of their pocket) to wander a half mile away with the tag. About 12 minutes after turning on Misplaced Mode, I acquired a message that the SmartTag was “noticed by a close-by gadget” with a dropped pin. I tapped Navigate within the app, which opened Google Maps and led me to a degree immediately throughout a reasonably busy road from the place my good friend was standing. If I’d left the tag behind someplace I’d just lately been, simply seeing the placement on the map would have been sufficient to jog my reminiscence as to the place I might need dropped my stuff. But when somebody had stolen the tagged merchandise and I used to be wandering the streets making an attempt to get it again, vigilante fashion, it could not have been exact sufficient to assist. It is probably not as correct because the iPhone-and-AirTag combo, however the SmartTag 2 is a strong entry within the Bluetooth tracker market and possibility if in case you have a Samsung telephone.

The Tile Slim is louder than each the Professional and the Mate, and practically equals the loudest tracker we examined, the Chipolo One. It really works with each Android and Apple units and its thick bank card form suits within the slots of a typical pockets (although it typically received’t join when inside an RFID-blocking pockets). The separation alerts you’ll get in the event you pay for a Tile subscription activate at about the identical distance because the Tile Professional, letting you get round 1,500 ft away earlier than pinging you a couple of left-behind merchandise. When utilizing an iPhone with Tile trackers, separation alerts not often got here and connectivity between the telephone and tracker was spotty at greatest, even in shut proximity. In the event you use an iPhone, the Chipolo Card Spot is equally loud, runs on Apple’s huge Discover My community and constantly provides you a left-behind alert at round 1,200 ft.

Bluetooth tracker FAQs
Which Bluetooth tracker has the longest vary?
Each the Tile Professional and the Samsung Galaxy SmartTag2 declare a most vary of round 400 ft, which is longer than the 200-foot declare for many of Chipolo’s tags. Apple doesn’t make comparable claims for AirTags. Any Bluetooth sign, nevertheless, relies on a number of elements. Obstacles like partitions and other people can block the sign, so a transparent line of sight is the one method to obtain the utmost vary. Different alerts, like Wi-Fi, also can intervene with Bluetooth connections. Even excessive humidity can have an impact and reduce the space at which your telephone will connect with your tracker.

That mentioned, you’ll see loads of tales about individuals discovering their automobile due to a Bluetooth tracker. Some police departments have even handed out trackers to fight excessive charges of carjacking. In most situations, the tracker of selection has been AirTags due to their huge discovering community.
