Battery Timer

About

Battery Timer shows a vertical battery gauge that drains from full to empty as the countdown progresses. Colour-coded segments shift from green through yellow and orange to red, and the charge percentage is displayed right on the battery. Because the metaphor is instantly recognisable, students and audiences can tell at a glance how much time is left without reading numbers.

How to Use

1. Select a countdown duration from the preset buttons.
2. Press Start — the battery begins draining.
3. Colour shifts as segments empty: green → yellow → orange → red.
4. The percentage overlay and stats row update each second.
5. When fully drained a notification sound plays.
