The COOKOO keychain is the perfect complement to your COOKOO watch and with it you can:
1) Use it as a remote for your camera — snap a picture remotely using the keychain
2) Use it as a waypoint remote — mount it on your bike, hang it from your backpack, etc. and drop a virtual pin on the connected map when you are out and about.
3) Use it as a phone finder when you know your phone is near, but can't seem to find it
Just like the COOKOO watch, it can also alert you on command (e.g. "find my keys") or when you have a notification and uses a Bluetooth SMART connection. Because of this, it has a 1 year battery life (just like the COOKOO watch) and can be used with the Connected App without interfering with your COOKOO watch experience.
It comes with a replaceable CR2032 battery (just like the COOKOO watch) and you can replace it yourself.
Best of all, its a great tool for developers and will ship in September so that you can develop your Connected Apps before the COOKOO watch is ready.
