Tether

A year ago, after one of us lost our phone in the back of a taxi, we realized that there weren't any products that could remind you not to leave your phone behind in the first place. That inspired us to make Tether, the first well-designed wearable that prevents phone loss.

Tether is the silent leash for your phone-a wearable that vibrates when it leaves the Bluetooth range of your smartphone. Just pair your phone and clip it on to your clothing to be reminded when you're about to forget your phone. It's dustproof and waterproof, so Tether can go wherever you go.
