Very simple app without a user interface or launcher icon, that sends a notification whenever the battery is 100% charged. It also FLASHES the NOTIFICATION LED, plays the standard alarm sound and wakes the screen up for 8 seconds.
I couldn't find any other app, that notifies exactly when the battery is at 100%, that is why I created this.
While not charging, it consumes no energy at all.
Fixed re-notification after killing the notification.
