Never lose your keys again with Hone!

The small Bluetooth 4 dongle ($50) pairs automatically with your iPhone 4S or iPad 3 and works in conjunction with a free app that emits an audible vibration or alert when you tap the “Find” button.

It runs for six months on an included battery and has a 150+ foot range.

Hone has a built-in proximity sensor so you’ll know when you’re getting closer or farther away.

Now you just have to remember where you last left your phone.
