I just downloaded the iOS app! Love the idea and the design! It looks so clean and fresh.
Just one thought: have you considered adding the track of the sun? It’s nice that the interface shows the current position of the sun. Yet without a movement indicator, I have no idea where the sun’s highest point is and what does the current position mean (is the sun at it’s highest? is it half way down?). It’d be interesting to see how the sun moves across the sky. :)
Thanks again for this great app!
