So I recently tried to shoot some pictures of the sunset at a specific location, but once I was to late and another time I came about two hours before the sun was, what I thought, in the right position but then again was in the wrong position.
After a bit of googling I stumbled across Helios, but sadly it's only for iOS; So now my question: Is there any good alternative for Helios on Android? or Is there any better way than using an app to time sunset pictures / pictures that involve the sun?
