How we picked and tested
Over the past few years, we've tested more than than a dozen Bluetooth trackers. The major players in this category are well known. But to make certain we didn't miss any, during our research for a previous version of this guide, we turned to Amazon and Google. The latter search turned up some great comparative reviews from Tom's Guide, The Wall Street Journal (subscription required), Wired, and Yahoo.
Here's what we look for in a corking Bluetooth tracker:
- Network size: Nearly Bluetooth trackers can utilize other phones that have the tracker's app installed to silently and privately search for your lost objects. The more people who use a platform, the amend your chances of recovering your lost stuff.
- Precision finding: Once you know the general location of your lost tracker, narrowing down exactly where it's hiding is the key to finding it. Trackers utilise a combination of concrete speakers and digital apps to help you locate your belongings.
- Size: A tracker that's too obtrusive to carry around with you or to attach to the thing you want to rails is useless. Smaller and lighter is meliorate.
- Range: The longer the range, the farther you can be from the tracker and still be able to discover your lost particular.
- Volume: If y'all're almost your tracker but can't hear information technology, that's no skillful. Despite having trivial space for a speaker, some of these tin can get quite loud.
- Other features: A replaceable bombardment isn't admittedly required, but it's a big plus. We also prefer trackers that can trigger an alarm on your phone. An app that is easy to navigate and updates location information quickly is important too.
Prior to the 2021 introduction of Apple'due south AirTag, the most important test nosotros conducted was to make up one's mind each tracker'due south potential range—how far away from the tracker we could move a paired smartphone before we lost the Bluetooth connection. In 2019, we tested the range in Wirecutter'southward 190-foot-long office in Long Isle Metropolis, New York. Nosotros ready each tracker on a shelf, triggered it to band, and and then walked abroad with our paired iPhone while noting the distance using a measuring wheel. Once the tracker'south smartphone app showed the tracker every bit out of range—or we physically striking the wall—we recorded the distance. We repeated this test at to the lowest degree 5 times per tracker and calculated the average distance for each across the measurements. Because AirTags leverage a much larger network and are more precise once you're in range, we still test the effective distance, just it's non every bit important.
Our pick if you have an iPhone: Apple AirTag
Our pick
If you use an iPhone and want to track your stuff, Apple's AirTag is easily the best pick. Compared with the competition, this tracker has 2 distinct strengths that make it our height option: The AirTag utilizes Apple'south huge network of devices to assist in finding the expanse where yous left your lost item, and precision tracking makes information technology easier for you to locate the exact spot. Taken together, these 2 features mean you're more likely to find what you're looking for with the AirTag than with whatever other Bluetooth tracking arrangement.
Apple isn't the start company to utilize a crowd-finding network for tracking purposes, but with a billion devices, its network has by far the largest number of devices that can wait for your stuff. Since 2019, Apple's Observe My app has used Bluetooth in every iPhone, iPad, and Mac that's on the network to passively and anonymously discover lost iPhones, Macs, and fifty-fifty contacts who share their location. Now AirTags can utilize the same system to report the location of any item y'all adhere them to. In practical terms, this ways if you leave your AirTag-equipped keys at the java shop, for case, equally long as someone at that place at some indicate has an Apple device, the keys' location will be reported to you (and the person with the iPhone or other Apple device who identified it volition never know). Although Tile's trackers piece of work the same manner, they do so on a far smaller scale—it'due south much more probable that the customer sitting one tabular array over has an iPhone than a Tile.
The other central characteristic of the AirTag works once you know your tracker's general location. Like the iPhone 11 and 12 series, AirTags support a wireless connection known every bit Ultra Wideband, which allows for precision locating at relatively brusk distances. Once you're in the general vicinity of your AirTag (say, the coffee shop where you left your keys), you tin can tap the Find push in the Find My app. The app then shows you the management and distance to the AirTag in question, and your phone vibrates as yous get closer and allows you to play a sound to assist in your search. In our testing the AirTag's tracking signal took a moment to lock on, but once it did we were thoroughly impressed past the system's accurateness.
Compared with Tile's trackers, AirTags have a much shorter Bluetooth range. Apple tree doesn't state whatever specific figures, simply nosotros found that the tracker maintained a connexion to our test iPhone for simply xxx feet or then. On the face of information technology, that doesn't sound peachy, just wandering around your office or home looking for your keys isn't that unlike from using a Tile with a 100-foot range. And we call up Apple'south much, much larger crowd-finding network and precision locating are more important factors, since that'south what volition go far more likely that you'll recover stuff yous've truly lost.
With its sleeky, white plastic front end and metal back, the AirTag looks and feels a lot similar a pin-dorsum button you might put on a jean jacket or backpack. The diameter is a little larger than a quarter, and the tracker is actually about a millimeter or two thicker than many iPhones, although its curved design makes it experience thinner. You lot accept the choice to add together custom engraving when yous order from Apple, with upwards to four characters (letters and/or numbers) or selected emoji; if you purchase the 4-pack, you tin can get different text on each. Noticeably absent-minded is any sort of zipper mechanism such as a key-ring hole or adhesive back. Instead, yous have to purchase an actress accompaniment. Of grade, Apple sells a handful of its own, and plenty of tertiary-party companies sell all sorts of designs, as well.
If you lose an AirTag (or an item containing or attached to ane), you can use the Notice My app or ask Siri to trigger an audible warning from the AirTag. The melody plays for virtually six seconds, with a repeating series of beeps. We establish both the tone and the book sufficient to help usa observe the AirTag when it was subconscious around our testing space, comparable to what we've experienced with Tile trackers. If your AirTag is cached nether a pile of clothes, for instance, you may not hear it, but the tone should otherwise be audible as long as you're in the same room.
Cheers to Apple'south control over both the hardware (the iPhone or iPad and the AirTag) and the software, the setup process to activate a new AirTag is foolproof. When you lot unpack a new AirTag and place information technology adjacent to your phone or tablet, a pop up appears on your screen, much like when you lot're pairing a set of AirPods or an Apple Spotter. Once you tap Connect, y'all can set a name for the AirTag and annals it to your Apple tree ID. There are no settings or menus, and the unabridged process takes under a infinitesimal. Tile's setup isn't any more difficult, simply you do demand to manually launch the Tile app kickoff, which is an extra step.
You rails and manage your AirTags in Apple's Discover My app, where you lot can meet the location and options for each tag. You lot tin too rename or remove an AirTag on this screen, with the latter option resetting information technology completely, unpairing it from your Apple ID and allowing someone else to use it as if it were new. Upward to 16 AirTags tin can be continued to an business relationship.
1 surprising but much-appreciated feature: Each AirTag runs on a removable, user-replaceable battery. It's the simply Apple-designed production to make the procedure easy. When the bombardment runs low (Apple says you lot should expect nigh a yr out of it, roughly the same every bit a Tile battery), the Detect My app notifies you, and y'all can bandy in a new CR2032 battery by twisting off the AirTag's metal dorsum, removing the sometime battery, and popping the new ane in. Fifty-fifty with this accessible design, AirTags are IP67 rated, so they should survive existence under 1 meter of water for up to 30 minutes, although Apple warns: "Splash, water, and dust resistance are non permanent atmospheric condition and resistance might decrease every bit a result of normal wear."
You tin can tap whatsoever relatively recent iPhone or Android phone confronting an AirTag, which will trigger a website showing the serial number of the tracker and instructions on how to disable it (by removing the bombardment). The wireless connectedness that happens here is the same kind—near-field communication, or NFC—that lets yous tap an iPhone or Apple tree Spotter near a store'south payment last to use Apple tree Pay. In this case, NFC serves to identify lost goods attached to the tracker, or to assist you determine whether someone might exist using the AirTag to track you without your cognition. If the AirTag has been set to lost manner, the owner's phone number will appear on your screen and so that you tin can phone call them to render their lost particular.
In autumn 2021, Apple updated the AirTags's firmware to include separation alerts, which notify you lot if you go out your keys behind, for example. This is a common feature among Bluetooth trackers, but it was omitted when the AirTags offset launched. It's very well implemented here. You can toggle the alerts on and off per device, and y'all can set exceptions—say, if you lot don't need to be alerted every time you lot leave home without your AirTag-armed backpack—with minor, medium, or large separation radiuses, depending on the sensitivity level yous demand.
Flaws only not dealbreakers
Dissimilar Tile's trackers (and some others), the AirTag doesn't have whatsoever way to ring your telephone if it'due south nearby. So if information technology's your iPhone that'due south lost, you'll have to rely on the Find My app on another Apple device to detect it.
In that location's no way to share an AirTag with some other person considering the tracker can be associated with only one Apple ID, even if you apply Apple tree'due south Family Sharing plan. If you share a ready of keys with a partner or roommate, for example, simply one of you volition be able to track them in the Find My app.
Because AirTags don't have any way to attach to your stuff directly, the actual toll is higher than the toll of the tracker itself, unless you program on simply tossing i loose into a bag or pocket. Apple's fundamental rings and loops all cost at least as much as a unmarried AirTag, effectively doubling the toll (not to mention the company'southward $300 to $450 Hermès models, which we are linking to simply so that you believe the states). Obviously, you lot tin can save quite a chip past ownership from a third-party accessory maker. We'll be testing some holders soon and including a few of our favorites in an update to this guide.
Our option if you have an Android phone: Tile
Our pick
AirTags don't piece of work with Android phones, just that doesn't mean non-Apple folks don't have a practiced tracker pick. Tile's Bluetooth trackers, including the Tile Mate (2022), the Tile Slim (2022), and the Tile Sticker (2022) (besides available packed together in the Tile Essentials bundle), are the next near popular, and then they have the 2nd-largest crowd-finding network. They also offer impressive range and alarm volume, and are sized and shaped in more than convenient ways: You tin put a Tile Mate on a keychain without ownership an extra holder, sideslip a Tile Slim into your wallet, or attach a Tile Sticker to whatever flat surface.
If your Tile is out of Bluetooth range, you can view a map displaying its location the last fourth dimension your phone fabricated contact with information technology. If your phone is no longer at that location—or if you're worried that it won't be—yous tin can mark the item as lost, which invokes Tile'southward crowd-finding feature. Tile tells us it has sold more than than 40 one thousand thousand trackers. That doesn't mean all of them are currently active, and a big portion likely aren't; early Tile trackers didn't have replaceable batteries, which meant the unabridged device had to be replaced annually. Then the total number of Tile units that make up its crowd-finding network is a tiny fraction of Apple tree'south. According to the company's figures, all the same, "millions of items" are found daily, and of those marked as lost, Tile says 90% are found.
AirTags come in merely ane round, button-like pattern, but the Tile line offers more options. The Tile Mate has the virtually general-purpose design, with an opening in the top-left corner that lets yous attach a keychain, lanyard, or similar tether. Information technology's a round-cornered square that'south around ane.49 inches beyond and 0.28 inches thick—smaller than a matchbook. The Tile Slim is designed to slide easily into a wallet; information technology'due south in the shape of a credit carte du jour, and at ii.v millimeters, it'southward as thick as three of them. The Tile Sticker is roughly the size of five quarters stacked, and the small, round tracker sticks with adhesive to any yous desire to track. This makes the Sticker a good option for anything that doesn't take a key band or tether, and because this tracker is so pocket-size, you tin attach it in a unimposing spot.
In our distance examination, all four Tile variations offered impressive range. We placed them at one end of Wirecutter's 190-foot-long function, and all remained connected to our telephone as we walked to the other end. We were able to hear them chirping from that far, besides, which ways you'll likely be able to hear them in almost houses or apartments (190 anxiety is more than double the length of a basketball court).
While the previous-generation Tile Mate ran on a user-replaceable CR1632 lithium bombardment, the newest edition has a sealed-in bombardment that's supposed to last for up to iii years. Tile insists that the tracker is recyclable at the end of its life, only we can't aid but see this as a step backward in terms of hardware longevity. Unfortunately, neither the Tile Slim nor the Tile Sticker use a replaceable battery either, though Tile says their batteries likewise last for upwardly to three years. (The Tile Pro has a replaceable battery that should last you about a year earlier yous'll need a new one.) The entire Tile lineup is rated IP67, and so each tracker is protected confronting dust and should survive existence submerged in water up to one meter deep for up to 30 minutes.
The Tile Mate, the Tile Pro, and the Tile Slim now take QR codes on the back that read, "Scan me if found." When scanned, a website that says the attached particular is lost pops up on the finder's phone; doing so sends the Tile'due south location to its owner. The owner can besides choose to put the Tile in lost mode and share their phone number and a message so that the finder can text or call them to return what's been lost.
Tile offers Tile Premium, an optional, $iii-per-month (or $xxx-per-year) subscription plan that covers as many Tiles every bit you lot own. The service includes free bombardment replacements shipped to you each year (for the Tile Mate and the Tile Pro), an extended warranty (from one yr to iii), and SMS-based support. On the software side, it offers a 30-twenty-four hours location history, unlimited sharing of your Tile trackers' locations, and smart alerts that let you lot know when y'all've left home without whatsoever of your Tiles. (The last feature is based on entering your home address, and in our testing we could get a third of a mile away before receiving the warning, which isn't super handy.) Aside from separation notifications, Apple doesn't provide whatsoever of these features with an AirTag. For $100 a year, Tile also offers Premium Protect, which has the same features plus a $1,000-per-year reimbursement for (about) registered items that are lost. Tile Premium is an unnecessary expense for well-nigh people, just Premium Protect may exist worth the investment if you're tracking something valuable.
Setting up any Tile is simple: Instead of having to become into your telephone's Settings menu to add together the Tile, the Tile app (Android, iOS) handles everything. You just launch the app, tap a button to add together a new Tile, and printing firmly on the Tile'south centre button when prompted. If yous take an iPhone, Apple tree'south AirTag setup may exist a trivial more automatic, just both processes are fast and unproblematic.
In the app, you lot can proper name each Tile whatever you like and add a photo; for example, if you lot have a Tile Mate in your backpack, you tin add together a photo of the backpack for that item Tile. Y'all can view your devices—all Tiles, your paired phone, and any other phones and tablets running the Tile app under your account—in list or map fashion. You tin can pair an unlimited number of Tiles with a phone, but simply four Tiles can actively communicate with an Android telephone (via Bluetooth) at once. An unlimited number of Tiles can communicate with an Apple device at once.
Tiles have less precision than AirTags over short distances because they employ a standard form of Bluetooth, without the layer of Ultra Wideband applied science that makes the Observe My app so accurate. In oral testimony to Congress (PDF) presented by its general counsel Kirsten Daru in April 2021, Tile said information technology had adult a product that uses Ultra Wideband technology but that Apple was preventing compatibility with iPhones.
What to look frontwards to
Chipolo unveiled a credit card-sized version of its Find My-compatible tracker chosen Chipolo Card Spot. Designed to fit in your wallet, the tracker is similar to the Tile Slim, just works with Apple tree's larger network. We'll be testing it when it'southward released.
Tile announced in October 2021 that an Ultra Wideband version of the Tile Pro will brainstorm shipping in early 2022. Different Apple tree'due south AirTags, the revamped Tile Pro will work with both iOS and Android operating systems, assuasive any smartphone user to track their lost items with precision. Pricing and an exact release appointment have non yet been revealed.
Apple issued a statement with a number of forthcoming changes to the Find My and AirTag ecosystem meant to help protect against unwanted tracking. Some of the updates are more passive, including new privacy warnings telling you not to stalk people, fixing a bug that caused the system to brandish "unknown accessory detected" when unknown AirTags are with you lot, and new documentation. An update to the iPhone'southward precision finding arrangement that shows where unwanted AirTags are, and an alert on your screen alongside an unwanted AirTags beep, seem like more meaningful improvements. No set date has been given for these changes.
What well-nigh privacy and security?
Striking a balance betwixt privacy and security with an item meant to track your stuff is difficult, and a device that tracks your location presents a number of concerns. Beyond the worry about what the tracker maker does with your location data, there's also the potential for intentional misuse and abuse by bad actors. Apple and Tile take different approaches on both fronts.
Apple says it designed the AirTag with privacy in heed. Because the location data is encrypted end-to-cease, no one other than you—not even Apple—tin can see where your AirTag is. Dorsum when Apple tree made the AirTag announcement and released the details, the visitor too outlined the device's built-in protections intended to prevent AirTags from enabling certain types of corruption. For instance, if someone tries to track you surreptitiously by throwing an AirTag into your bag, your iPhone (if you apply one) will notice a foreign tracker post-obit you lot around and send you an alert. If you're an Android user, you tin download the free Tracker Detect app to scan for AirTags that may be surreptitiously spying on you. According to CNET, the AirTag will start beeping within eight to 24 hours of existence separated from the owner's phone (downward from three days when the tracker first launched). The Washington Mail service (subscription required), which extensively tested the AirTag privacy features with iPhones under that three-solar day window, concluded that the features Apple added to limit stalking may not deter bad behavior every bit much every bit one might hope. A New York Times written report notes, "In recent months, people have posted on TikTok, Reddit and Twitter about finding AirTags on their cars and in their belongings." If your secretly AirTagged item is stolen instead of lost, the thief may get the warning and could, theoretically, disable the tracking or only throw away the AirTag. Tile doesn't have a similar system, and so you won't know about a nearby planted Tile unless you physically find information technology.
Tile representatives have told us that the company uses your telephone'due south location data in iv ways: determining where y'all are in relation to your stuff, periodically determining the location of each tracker, noting your location if you're in range of someone else's lost tracker, and (if you contact Tile's support staff) determining the approximate location of your reckoner or other device by IP address. Nosotros don't think any of these uses is particularly invasive for a device that you're purchasing to locate you and your lost items, and Tile told u.s. it doesn't "use revenue generating advertizing in our products or services that could give third parties admission to certain data for monetary gain."
We combed through the privacy policies of both companies and reached out with clarifying questions about our almost disquisitional concerns regarding these types of trackers. Here's how they compare:
| AirTags | Tile | |
| Is the tracker'due south location accessible by the manufacturer? | No | Yes |
| Is location data in the community item-finding networks anonymized and encrypted? | Yes | Yes |
| Do y'all sell or share customer data or location data with tertiary parties? | No | No |
| Have in that location been any known data breaches in the past two years? | No | No |
| Is the privacy policy readable? | Yes | No |
The competition
Chipolo's One Spot uses Apple's Find My network, meaning information technology's just every bit likely that someone's iPhone will anonymously discover your lost tracker as it is with an AirTag. Only the One Spot has only one advantage over the AirTag—a keychain hole as office of its blueprint—and a number of disadvantages. It doesn't have the precise finding capabilities, it'southward not equally resistant to the elements, and information technology'south physically larger. Unlike the Chipolo One (2020) (which is physically identical only uses Chipolo'south crowd-finding network instead of Apple'due south), the I Spot can't exist used to trigger an alert on your phone, nor tin can it let you know if you lot've left something behind. There'south no reason to choose the One Spot over the AirTag, peculiarly since they cost about the same.
The Tile Pro (2022) is a more expensive and slightly larger, fox-shaped version of the Tile tracker, with a longer range. Tile says this model volition stay continued for upward to 400 feet, or 40 feet longer than the length of a football field. In our tests the Tile Pro remained connected for the unabridged length of our 190-foot role. Though a longer range is better, nosotros've concluded that in almost whatsoever scenario around a dwelling house or office, the Tile Mate is sufficient. If your firm is longer than 400 anxiety, you tin can swing the extra $x for the Tile Pro. The Pro is also the only current Tile tracker that uses a replaceable battery, merely information technology lasts just one yr, compared to the other models' three.
Orbit offers a number of tracker styles, including the Orbit Glasses tracker, which fits on eyeglasses or sunglasses, and the Orbit Card, a carte du jour-manner tracker that's even thinner than the Tile Slim. They're intriguing if yous need tracking in those specific designs, just unfortunately the Orbit network is just too limited for us to recommend choosing Orbit over Tile. Anecdotally, I lost a pair of sunglasses that were outfitted with the Orbit Glasses tracker in busy and tech-heavy New York City. And despite marking them as lost in the app in hopes of an Orbit user passing by and finding them, I never received a notice that the sunglasses were found. Additionally, I wasn't alerted when the Orbit Card was running low on battery power, which could potentially lead to a lost wallet with no way to find it.
Cube offers three designs of its tracker: the Cube, the Cube Pro, and the Cube Shadow, the concluding of which is a slim, wallet-friendly size. Though the Cube Shadow promises the same range as the Tile Slim, the Cube and Cube Pro offer half the range of the Tile Mate and Tile Pro, respectively, and the entire Cube family has a smaller oversupply-finding network than Tile'south trackers.
