Here is an app for Smart Watches! Is it time to charge my phone? Do I have enough juice to get through the day? Charge Checker allows you to easily see the battery life on your watch or your phone and alerts you when one or the other gets low.

Now the phone also tells the watch when the battery has dropped too low.

Charge Checker is the smart and simple way to stay on top of your charge and keep running. Just say "Start charge checker" to get a beautiful and easy to read animation of the battery level on your Android Wear watch. If the charge drops low, if it goes down to 15%, this app will send a notification to your phone. With version 1.1, the phone does the same thing. It displays the battery animation and sends an alert to the watch when the battery drops down to 15%.
