If you're an Apple user, AirTags use Find My to track anything that you can put these devices on. Right now, Amazon has the four-pack for $67.99 (originally $99)—a new record-low price according to price-tracking tools—likely because the AirTag 2 release date is approaching. If four is too many, you can also get a single AirTag on sale for $22.99 (originally $29).

The AirTag works with Apple's network of iOS devices to create a Bluetooth tracker. 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 on 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.
