Perfect solar panel alignment in seconds. TiltSync transforms your iPhone into a precision alignment tool for solar panels.

Whether you're a homeowner installing rooftop panels, an RV enthusiast with a portable setup, or setting up your first off-grid system, TiltSync helps you maximize energy production with zero guesswork. **How it works:** Place your phone flat on your solar panel. TiltSync uses your device's accelerometer to measure tilt, the magnetometer for compass heading, and GPS for your exact location. The app calculates the optimal angle and direction, then guides you to perfect alignment with haptic feedback that intensifies as you dial it in. **Precision interface:** The main display shows a rotating compass card with your heading, a tilt indicator showing panel angle, and real-time digital readouts. It's not just functional, it's beautiful to use. **Three alignment views:** • Combined Dashboard — See tilt and compass alignment together on one screen • Tilt Mode — Classic bubble level for dialing in your angle • Compass Mode — Dedicated view for azimuth alignment with sun position marker **Three optimization modes:** • Year-Round — Set it and forget it. Best fixed angle for maximum annual production. • Seasonal — For adjustable mounts. Optimized angles for summer and winter. • Daily — Real-time sun tracking that updates every minute. Perfect for portable panels, camping, and off-grid setups where every watt counts. **Features:** • Precision interface — Compass, tilt indicator, and real-time readouts • Dark, light, and auto themes — Adapts to your preference or system setting • Color-coded feedback — Green when perfect, yellow when close, red when off • Progressive haptic guidance — Feel your way to alignment without watching the screen • Instant startup — Cached GPS location means no waiting on subsequent launches • Works fully offline — All calculations happen on-device • No account needed — Just open and align **Built for everyone:** No solar experience required.
