Very fast calculations. Super accurate results. Not restricted in time: one can go way back and forward. It remembers the latest settings so you can make alterations quickly. Most impressive app!!!
Not a bad app, just beginning to use it. But right off I wish it would give the 3 twilight times for the sun and moon phase name, such as "waxing crescent." Even show the moon shape too. Of course, since it gives # of days before a major phase event, in today's case the 1st quarter (3.? Days to go), then it's easy enough to determine the current phase name.
