Smart trackers that can help you find any lost item in seconds

AirTags are great because they use the Find My network, which taps into millions of Apple devices. So, suppose you lose your backpack, wallet, keys, or any of a hundred other items you can attach an AirTag to. In that case, it sends out a signal to nearby iPhones anonymously. Then, the location updates in your app, and you can watch it move on a map in real-time. And when you’re near, it guides you with distance and direction. There’s even a built-in speaker that can produce sound if it’s hidden under the couch. When traveling, tossing one into your suitcase can give you some peace of mind at baggage claim.

Most of the time, you won’t even notice an AirTag until you need it. The batteries last about a year, and they use a standard CR2032 coin cell, which swaps out in a few seconds. The tags can withstand splashes and dust, making them suitable for rainy days and messy cars. You can clip them to keys with a simple holder, stick one in a luggage tag, or put one in a wallet sleeve. You can also share the location of an AirTag, which is handy if you need a family member or friend to grab a lost item.

Privacy is part of the design. Location information is encrypted, and both iPhones and Android devices will alert users if an AirTag they don’t recognize appears to be moving with them. Lost Mode lets you add a message and phone number, so if someone finds your item, they can tap it with their phone and contact you. It’s a smart way to make it easy to find your stuff, but hard for others to abuse the system.

If you’re tired of searching everywhere for your keys or double-checking your bag, this four-pack can fix that with almost no effort. The Apple AirTag 4 Pack is a small purchase that helps you stay organized. And at $65 on Amazon right now, down from $99.
