Cold weather is an especially rough time for keeping track of ones keys so many more layers with so many more pockets really, they could be anywhere. Stick a Bluetooth tracker on your keyring and suddenly finding items is as easy as tapping a button in an app. Of course, these trackers are good for bags, luggage, wallets and even jackets themselves. And if something goes missing out in the city, an anonymous finding network can help lead you to your lost item. We tested out most of the major tracker brands out there, comparing their everyday utility, compatibility, the size of the connected networks and other handy features to help you find the best Bluetooth tracker for you. What to look for in a Bluetooth tracking device Bluetooth trackers are small discs or cards that rely on short-range, low-energy wireless signals to communicate with your smartphone. Attach one of these gadgets your stuff and, if its in range, your phone can ring the chip so you can find it. These tracking devices offer other features like separation alerts to tell you when youve left a tagged item behind, or where a lost item was last detected. Some can even tap into a larger network of smartphones to track down your device when youre out of range. Depending on what you want the tracker to do, there are a few specs to look for when deciding which to get. Device compatibility Like most things from the folks in Cupertino, AirTags only work with products in the Apple ecosystem. The company has opened up access to its Find My network to third-party manufacturers, including Chipolo and Pebblebee. Those finders work with Apple's large tracking network, but only pair with Apple devices. Chipolos classic trackers will work with either Android or Apple devices, as will Tile trackers. Samsungs latest fob, the Galaxy SmartTag2, only works with Samsung phones, but new tags from Chipolo and Pebblebee that rely on Googles new Find My Device network will work with any Android phone (running Android 9 or later). Finding network Crowd-sourced finding capabilities are what make headlines, with stories about recovering stolen equipment or tracking lost luggage across the globe. Using anonymous signals that ping other peoples devices, these Bluetooth tracking devices can potentially tell you where a tagged item is, even if your smartphone is out of Bluetooth range. Apples Find My network is the largest, with over a billion iPhones and iPads in service all running Apples Find My app by default. So unless an iPhone user opts out, their phone silently acts as a location detector for any nearby AirTags. Apple recently increased the AirTags finding power by enabling you to share the location of a lost tag with a third party, like an airline. Chipolo fobs that work on Apples network have the same ability. Now that Googles Find My Device network is up and running, its a close second for the largest in the US. Like Apple, Android users are automatically part of the network, but can opt-out by selecting the Google services option in their phones Settings app and toggling the option in the Find My Device menu. Samsungs SmartTag 2 and related network also defaults to an opt-in status for finding tags and other devices. Tile offers a large finding grid that includes Tile users, Amazon Sidewalk customers and people running the Life360 network. Life360 acquired Tile in 2021, and, according to the company, the Life360 network has more than 70 million monthly active users. In our tests, AirTags offered nearly real-time location data and were quickest to find items abandoned in spots around Albuquerque, including a bar, bookstore and coffee shop in Nob Hill, along with various outdoor hangouts on UNMs campus. Samsung's SmartTags were able to locate our lost items most of the time, though not with the same precision finding accuracy as AirTags. Googles newish Find My Device network was a little slower than Apples network when using the community finding feature, but the accuracy was better than Samsung. In our tests, Tiles finding network wasnt able to consistently locate its lost fobs. Chipolos classic trackers, on the other hand, dont have much of a crowd-sourced network to speak of. Yet as we used the trackers, the size of the finding network started to feel less important in the face of typical, everyday use cases. It was their ability to out-perform in every other way that boosted Chipolos classic trackers to the top of our list. Amy Skorheim / Engadget Separation alerts Heres where a trackers day-to-day utility really shines. A separation alert lets you know when youve traveled too far from your tagged items, which is useful if you want to make sure your laptop bag, or jacket or umbrella always comes with you when you leave the house. These notifications work when youre out and about too. If youve got a Bluetooth tracking device in your wallet and walk out of a restaurant without it, the separation alert should kick in, resulting in fewer lost items. This feature also tells you where your tagged item and phone were last paired, allowing you to retrace your steps if you happen to miss the alert. Each tracker handles left-behind items differently. Both AirTags and Chipolo include the feature by default. Tile trackers require a yearly subscription to enable the alerts (currently $30 per year). And tags working with the Google Find My Device network dont offer the feature at all. Both AirTags and Tiles allow you to turn off separation alerts at certain locations, meaning you can set your home as a safe place where items can be left behind, but alerts will still trigger elsewhere. Chipolo doesnt offer safe locations, but you can toggle out-of-range alerts on a per-item basis. In our tests, the Chipolo sent an alert after we got between 250 and 450 feet away from our tagged item. AirTags alerted us between the 600- and 1,400-foot mark. And Tiles sent a notification after about an average of 1,500 feet. Tile notifications were more consistent when using an Android phone than an iPhone. Connectivity, volume and design The feature you may use most often is the key finder function, which makes the tracker ring when you hit a button in the app. With Apple's AirTags, you can say "Hey Siri, where are my keys?" and the assistant will ring the tag (assuming it doesn't mistakenly think you're asking for directions to the Floridian archipelago). Asking Alexa or the Google Assistant to find your keys will work with Chipolo, Tile and Pebblebee trackers linked to your Android device. The SmartTag2, Tile, Chipolo classic and Pebblebee trackers using the Pebblebee app will also let you double click the device itself to make your phone ring. AirTags and any third party tags running on either the Find My (Apple) or Find My Device (Google) app dont offer this feature. The volume of the Bluetooth tracking device may determine whether you can find an item buried in your couch cushions or in a noisy room. AirTags have a reputation for being on the quiet side, and that aligned with what we saw (measuring roughly 65 decibels). All three versions of Chipolos keychain-style tags and Tiles Pro model were the loudest, measuring between 83 and 86 decibels on average. Design will determine what you can attach the tracker to. AirTags are small, smooth discs that cant be secured to anything without accessories, which are numerous, but that is an additional cost to consider. Chipolo, Pebblebee and Tile offer trackers with holes that easily attach to your key ring, and all three companies also offer card-shaped versions designed to fit in your wallet. Batteries are replaceable for AirTags, Tile Pro and Chipolo One; the first two have a one-year battery life and the Chipolo can go up to two years. Tile Mate and all card-shaped trackers dont have replaceable batteries, which means youll have to replace the entire unit whenever it dies. Pebblebee trackers are rechargeable and come in both a key fob and wallet variety. Stalking, theft and data privacy AirTags have gotten a lot of attention and even prompted some lawsuits for Apple due to bad actors planting them on people in order to stalk them. While this fact may not influence your buying decision, any discussion of Bluetooth trackers should note what steps Apple, Google and Tile have taken to address the issue. Last year, all the major players in the Bluetooth tracker business teamed up to combat misuse and standardize how unauthorized tracking detection and alerts work for iOS and Android. Last year, Tile launched a feature called Anti-Theft Mode, which enables you to render one of its trackers undetectable by others. That means if someone steals your tagged item, they wont be able to use the anti-stalking features to find and disable the tracker. That sort of negates one of the major ways potential stalking victims can stay safe, so Tile hopes ID verification and a $1 million penalty will deter misuse. Separately, Tile was recently hit by a data breach, raising different privacy concerns. The company issued a statement about the event, which it shared with Engadget: Similar to many other companies, Life360 recently became the victim of a criminal extortion attempt. We received emails from an unknown actor claiming to possess Tile customer information. We promptly initiated an investigation into the potential incident and detected unauthorized access to a Tile customer support platform (but not our Tile service platform). The potentially impacted data consists of information such as names, addresses, email addresses, phone numbers, and Tile device identification numbers. It does not include more sensitive information, such as credit card numbers, passwords or log-in credentials, location data, or government-issued identification numbers, because the Tile customer support platform did not contain these information types. We believe this incident was limited to the specific Tile customer support data described above and is not more widespread. We take this event and the security of customer information seriously. We have taken and will continue to take steps designed to further protect our systems from bad actors, and we have reported this event and the extortion attempt to law enforcement. We remain committed to keeping families safe online and in the real world. As a theft deterrent, a Bluetooth tracker may or may not be the best option. Anecdotal stories abound in which people have recovered stolen goods using a tracker but other tales are more cautionary. Neither Apple nor Google promotes its trackers or finding networks as a way to deal with theft. GPS trackers, on the other hand, are typically marketed for just that purpose. How we tested Before deciding on which trackers to test, we researched the field, looking at user reviews on Amazon, Best Buy and other retailers, along with discussions on sites like Reddit. We also checked out what other publications had to say on the matter before narrowing down our picks to Apple AirTag, Tile and Chipolo trackers. When Samsung's SmartTag 2 came out in October of 2023, we added that to our testing, along with Pebblebee's rechargeable Chip tracker. After Google launched its Find My Device network we added compatible fobs from Chipolo and Pebblebee to the mix. Heres the full list of every tracker we tested: Apple AirTag Chipolo Card Spot Chipolo One Spot Chipolo One Chipolo Card Pebblebee Clip Samsung SmartTag 2 Chipolo One Point Pebblebee Clip for Android Tile Pro (2024) Tile Mate (2024) Tile Mate (2022) Tile Pro (2022) Tile Slim (2022) After acquiring the trackers, I tested each one over the course of a few weeks using both an iPhone 11 and a Samsung Galaxy S22 Ultra. I recreated likely user experiences, such as losing and leaving items behind at home and out in the city. I planted trackers at different spots near downtown Albuquerque, mostly concentrated in and around the University of New Mexico and the surrounding neighborhood of Nob Hill. Later, I conducted tests in the Queen Anne neighborhood of Seattle. Each test was performed multiple times, both while walking and driving and I used the measure distance feature on Google Maps to track footage for alerts. I paid attention to how easy the app was to use, how reliable the phone-to-tracker connection was and any other perks and drawbacks that came up during regular use. Other trackers we tested Tile Pro and Tile Mate (2024) Tile recently came out with a new suite of trackers, replacing the Tile Mate, Tile Pro, Tile Sticker and Tile Slim with updated models. In addition to fun new colors for the Mate and Slim, Tile added an SOS feature that can send a notification to your Life360 Circle when you triple press the button on the tracker. Its a clever addition that turns your keys into a panic button, something offered by personal safety companies as standalone devices. There are a few caveats: You and the people you want to notify in an emergency will need the Life360 app installed on your phones. If you want your Tile to also trigger a call to emergency services, youll need a $15-per-month Life360 subscription (thats in addition to a Tile membership, which starts at $3/month or $30 annually). And enabling the SOS triple-press disables the ability to ring your phone with the fob. I tested the SOS feature and it did indeed send a text message to my Circle, with the message that I had triggered an SOS and a link to a website that showed my current location. I thought it odd that the link didnt open the Life360 app (which shows the location of users' phones), but I wasnt as much concerned with Tiles personal safety features as I was with the tracking capabilities, which turned out to be less than ideal. For my tests, I planted Tile trackers in a densely populated area of Seattle (about 15,000 people per square mile). After setting the trackers to lost in the Tile app, I waited. After four hours, one of the trackers was not discovered by the finding community, so I went and retrieved it. Another fob I planted alerted me that the tracker had been found by the Tile community after three hours but the location it gave me was off by a third of a mile. I then decided to plant a tracker in the most populated place I could think of the dried fruit and nuts aisle of a Trader Joes on a Friday evening before a major holiday. It still took over a half an hour before another Tile user anonymously pinged my lost tracker. In my tests with Samsungs trackers and the fobs on Googles Find My Device network, it took around ten minutes for them to be discovered. AirTags took half that time and all were tested in a far less populated city. Four hours with no ping and over a half hour before getting a hit in a crowded TJs were pretty long stretches. Our top pick, the classic Chipolo, has virtually no finding network. But if youre getting a tracker for that feature alone, you should go with AirTags if you have an iPhone or the Google-enabled Chipolo or Pebblebee trackers if you use an Android phone. We prefer the Chipolo because it works with either iOS or Android devices, it rings loud, its quick to tell you when youve left it behind and it connects nearly instantly when youre searching for a misplaced tracker around the house. Tile devices also work with both mobile operating systems and its latest models are indeed louder than they were before. But they arent as quick to connect and you need to pay for a membership to activate left-behind alerts. And when you do, those notifications dont kick in as quickly as they do with competing trackers. Bluetooth tracker FAQs Which Bluetooth tracker has the longest range? Both the Tile Pro and the Samsung Galaxy SmartTag2 claim a maximum range of around 400 feet, which is longer than the 200-foot claim for most of Chipolos tags. Apple doesnt make similar claims for AirTags. Any Bluetooth signal, however, is dependent on a few factors. Obstacles like walls and people can block the signal, so a clear line of sight is the only way to achieve the maximum range. Other signals, like Wi-Fi, can also interfere with Bluetooth connections. Even high humidity can have an effect and lessen the distance at which your phone will connect to your tracker. Remember, when considering the range of Bluetooth trackers, the size of the finding network also comes into play. This is the number of nearby phones that can be used to anonymously ping your tracker when your own phone is out of Bluetooth range. As of now, Apple AirTags have the largest network, followed by Googles Find My Device, Samsungs finding community, Tiles Life360 members and finally Chipolos own network. What is the best Bluetooth tracker for a car? Bluetooth trackers are designed to track small, personal items like keys, jackets, backpacks and the like. All trackers have safeguards to prohibit the tag from being used to stalk people, so most will alert someone if a tracker that does not belong to them is detected following them. That means a car thief may get tipped off that theres a tracker in the car theyre trying to steal. That said, youll see plenty of stories about people finding their car thanks to a Bluetooth tracker. Some police departments have even handed out trackers to combat high rates of carjacking. In most instances, the tracker of choice has been AirTags thanks to their wide finding network. How accurate are Bluetooth trackers? Accuracy for Bluetooth trackers can be looked at in two ways: Finding items nearby and finding items misplaced outside your home. For nearby items, youll most often use the ring function on the device to hunt it down. Two tags, Apples AirTags and Samsungs Galaxy SmartTag2, also use ultra-wideband technology, which creates directional navigation on your phone to get you within a foot of the tracker. Accurately finding lost items outside your home depends on the size of the finding network. Since this relies on the serendipity of a random phone passing within Bluetooth range of your tracker, the more phones on a given network, the better. And since Bluetooth ranges and distance estimates are only precise within about a meter or so, getting pings from more than one phone will help locating items. Here again, its worth noting that Apples Find My network is the largest, followed by Google, Samsung, Tile and Chipolo (both Chipolo and Pebblebee have fobs that work with the Apple and Google networks).This article originally appeared on Engadget at https://www.engadget.com/computing/accessories/best-bluetooth-tracker-140028377.html?src=rss
