I thought this was a brilliant idea for keeping track of keys, etc. But the app has a tragic flaw. It only works if location services are turned to always, even thought when traveling out of wifi range, this puts a huge load on the phone battery (you use a mobile app to find out where your keys are). Since adding this app, and activating my tile, my battery life has shot down. If I change location services to "when using the app" it tells me that my tile has been disabled. This needs to be fixed--much of the time we don't need our locations tracked since the tile is immobile, or we know exactly where the object is.
