Great app, works well. Just what I was looking for. It's a super fast hand held nautical almanac for the sun & moon. Data includes, daily pages, rising, setting, several twilights, altitude, azmuth, equation of time, right ascension, age/phase, eclipse dates, and more. A good looking and easy to use interface. Highly recommended for anyone interested in solar energy, home construction, gardening, astronomy, and hobby time keeping.
