Professor Snape may be sarcastic but one thing he isn't is irresponsible -- which is why you'll want to trust your most valuable items with the Professor Snape Foundmi 2.0 Personal Bluetooth Tracker. Attach your foundmi to anything and you'll be able to find it easily with the foundmi app. Just download the foundmi app from the App Store and pair the app to your foundmi personal Bluetooth tracker using any iOS or Android device to start tracking.
When you're in Bluetooth range, you can use the alert function to emit a loud alarm, so you can quickly find your stuff. Once paired, your foundmi can ring your phone if you lose it -- just double tap the button on your foundmi tag to trigger the feature and find your phone fast (even when your phone is on silent). Your foundmi also works as a camera shutter, and is perfect for long distance selfies and wide group shots.
Features replaceable battery (CR2032, a coin cell battery), which lasts up to 6 months. Works with iPhone 5S or newer, iPad 3rd Gen or newer, iPad Mini or newer, iPad Pro or newer, iPad Touch 5th Gen or newer. Requires iOS 9 or higher, Bluetooth 4.0.
