Tower Energy for iPhone & iPad

Native iOS Power Monitoring

Tower Energy brings professional battery runtime calculations to your iPhone and iPad with a native iOS interface optimized for touch. The app runs entirely on-device using local storage, ensuring your energy profiles and device configurations persist across sessions without requiring an internet connection. All calculations happen instantly on your device's processor, with no data sent to external servers.

Designed for the Apple Ecosystem

The app integrates seamlessly with iOS features you use every day. Dark Mode support ensures the futuristic dashboard adapts to your system preferences automatically. Split View and Slide Over on iPad let you reference runtime calculations while working in other apps. The compact 6.1 MB download installs in seconds over cellular or Wi-Fi, and the app launches instantly with no loading screens or account setup required.

Optimized for iPhone and iPad Screens

On iPhone, the vertical layout prioritizes quick access to runtime estimates and total consumption with large analog gauges that respond to swipe gestures. iPad users benefit from a wider dashboard layout that displays energy sources, device lists, and simulation controls simultaneously in landscape orientation. Both interfaces use high-contrast neon colors against dark backgrounds for visibility in low-light emergency scenarios, and all interactive elements meet Apple's 44-point touch target guidelines.
