HONE for iPhone – Never Lose Your Keys Again
If you’re a person who finds it difficult finding their keys, Hone is your savior. Hone is a neat little device which you attach to your keys, when you can’t find your keys, you launch the Hone app on your iPhone and the Hone keyring will light up, vibrate and make sounds to help you find your keys. It runs for 6 months on its battery and has a range of 150+ feet.
It will only work with the iPhone 4S though because that is the only iPhone to use Bluetooth 4.0 which uses a lot less power than previous generations.It’s not for sale yet because its a Kickstarter project
