Really love the simplicity of this app, others try to pack in features but this is straightforward and nearly perfect. My only concern was the dot seemed to stay center even when the phone is "yawed" around the dot itself, which swings the base out to a new location and therefore the face to a new direction.. Still very usable for an overall approximation. A calendar option would be great to align for certain times of year (I can only walk out on the ice to adjust in the winter..!) thanks!

This app is so simple I really didn't think it would work. Other apps give heaps of information, but this does everything needed to set up my portable solar panel when camping.
