Charged was developed to provide an alert when your device has been fully charged.
The application's core is its background service that monitors the battery state when charging.
It will post a notification (using your default alarm's ringtone) when the battery is fully charged or has charged to a specifiable level.
The app's GUI was added to provide basic battery statistics, a simple "enable/disable" option for the service, a numeric entry form to trigger the alert at a specific charge percentage, and a modifiable alert tone.
Enjoy the app, feel free to rate/comment/critique
