Hmmm. The interface is clean and easy to use, but the app sends me notice of solar noon as the best time to make vitamin D, as if it were possible to get vitamin D from the sun on a December day in Pittsburgh. It’s not and won’t be for many more weeks.

I love the display / looks / GUI, However one of the main reasons I downloaded it has a major flaw/bug: Going to use the Sun tracker/timer If you go out of the app or do anything else other than leave the timer running I've noticed 99% of the time it turns off / stops/resets to zero 😢. ALSO, see anyway of adding/deleting/editing any of my previous saved Sun Timers... PLEASE FIX, = 5 ⭐
