If you're an Apple user, AirTags are the easiest way to keep track of just about anything. Just clip them onto a wallet, a keyring, a suitcase, or even a pet, and use the Find My app to see where they are. Right now, the 1st Generation four-pack AirTags is selling for $59.99 (originally $99)—a new record-low price, according to price-tracking tools. This deal is also a much better value than buying a single AirTag, which costs $22.99 as opposed to just under $15 each if you go for the four-pack. The discounts are likely because the AirTag 2 was released earlier this year.

AirTags are mostly marketed for purses, keys, and travel bags (airlines are adopting their use now), but there are examples of people using them much more creatively—like putting one on a dog's collar and training them to come back whenever the "play sound" feature is activated. The AirTag works with Apple's network of iOS devices to keep its location precise. Essentially, every person with an iPhone (or iPad) is part of this iOS network, and as long as one of these people gets within Bluetooth range of your AirTag, it will show up as the last location on your Find My app.

As you can see in PCMag's "excellent" review of the AirTag, the Find My app has a screen that points you in the direction of your AirTag like a compass, including the distance it is from you. There is also an option to play a sound, which is perfect for locating, say, a remote that's buried under the couch.

Once the AirTag is more than 30 feet from your phone, the network of iOS users will kick in. When the AirTag is closer than 30 feet, it uses your own Bluetooth. There are security measures in place set by Apple, including end-to-end encryption, so that nobody (not even Apple) knows where your AirTag is except for you. The batteries last about a year and are replaceable. There is also no monthly charge for these, unlike competitors like Tile or Chipolo for Android users.
