Remember to take your phone with you when you get up to leave.
This app installs on your Android Wear device and alerts you when it loses contact with your phone. Now you'll remember to go get your phone before you have a chance to really lose it.
You can also choose to have your phone notified when it loses contact with your watch. Wouldn't want to leave it stuck at home while you're out, would you?
Alert delay option minimizes the alerts you'll receive due to random disconnect/reconnects (they happen to everyone). They delay can be as short or long as you choose.
