Nice visualization

Very nice visualization, good alarm functions. The only app that lets me set an exact alarm for twilight (not only sunset)!
One drawback: Apparently the app queries the location continuously while it is open. This produces unnecessary battery drain; one short location check when the app opens would be sufficient.
Of course, you can disable the access to Location Services in the preferences, but then you get ugly message pop-ups when you tap the Reset icon.
