A cross-platform React Native app that monitors your battery level and sounds a persistent alarm when it drops below your chosen threshold. The alarm only stops when you plug in your charger.

Built for people who forget to charge their phone and end up with a dead battery during the day.

• Persistent alarm sound that only stops when you plug in
• Background monitoring — alerts fire even when the app is backgrounded or killed (Android)
• Event-driven monitoring with minimal battery impact
• Works on both Android and iOS
• WCAG AA accessible for older users
• Dark theme to save battery on OLED screens
