Apple AirTag

$29 (1 pack), $99 (4 pack) From Apple.com

Features IP67 splash, water & dust resistant, U1 chip, NFC, replaceable battery

DESIGN

With a white front and a chrome metal back, the AirTag stands out. Two downsides of its design: when you want to attach it to something — a keyring or a bag — you need to purchase the optional accessory. An Apple key ring costs a frightful $35. It’s also a scratch–magnet.

FEATURES

Though it might look a bit fragile, the AirTag actually boasts an IP67 rating, making it splash, water and dust resistant. It can also be submerged in water for 30 minutes at a depth of 1–meter. There’s a replaceable CR2032 battery which Apple says lasts for a year.

CONNECTIVITY

Along with Bluetooth for proximity finding, the AirTag also comes with Apple’s U1 Ultra Wideband chip, and NFC. Ultra Wideband allows it to use Precision Finding in Find My, showing you both direction and distance to the AirTag. It only works on iPhone 11 and 12, though.

MELODY

When Play Sound is activated in the Find My app, the AirTag plays a delightful melody with an ear–bothering crescendo, so it’s easy to find. A minor downside is it only plays once — you have to manually activate it each time.
