Looks like a cool app. I've been using an app combo, The Photographer's Ephemeris and Sky & Telescope's SkyWeek +, for this stuff. An all-in-one should be handier…must check it out.
(Attached pic: the Moon & Jupiter conjunction on July 8. I used the app combo to choose a workable camera location in my tree-filled, lower-sky-obscuring neighborhood.)
