I would give it Five Stars -- If it worked

This is handy app for people who boat or shoot photos or fish and need to knew which the phase the moon is in. In "Lunar Mode" the app effectively shows the progressive moon stages, day-by-day throughout the current month. Swell! However, an earlier reviewer is precisely right -- you cannot flash forward a month (youre supposed to be able to do this) and the thing jumps back two months when you try to regress. After that, there is no return, save for closing and starting over.
