Exactly right. The Cobra Tag uses traditional Bluetooth, so it has to be recharged every couple of days; we use Bluetooth low energy and a removable battery that lasts 6+ months. They don't support iPhone and we (currently) don't support Android.

I'd love to have this but it being iOS-only kills it for me. Any thoughts on opening up the spec? I'd love to implement this for both my laptop (Linux) and my Boot2Gecko phones.

  It uses a custom UUID for advertising, but other than that it uses standard Bluetooth LE profiles for notification and battery status, so you should be able to do it...
