Qrio Smart Tag

Qrio Smart Tag is a compact Bluetooth tracker from Qrio, Inc. that helps you keep track of your important items. The app lets you ring the tag from your iPhone when it's nearby, view its location on a map, and use the tag button to ring your phone or trigger a camera shutter. It requires iOS 11.4+ and works with iPhone 5s and newer.

If the tag is out of range, location information can be shared via other Qrio Smart Tag users, increasing your chances of finding items as more users join. Note: Continued use of GPS running in the background can dramatically decrease battery life.
