Apple AirTag is a super easy way to keep track of your stuff. Attach one to your keys, slip another in your backpack. If your AirTag is nearby, your iPhone can lead you straight to it with Precision Finding. You will see the distance to your AirTag and the direction to head in all thanks to Ultra Wideband technology. AirTag is designed to keep going for more than a year on a standard battery that you can easily replace. And your iPhone lets you know when it is time to pop in a new one. The AirTag is water resistant.
