Type in an object (planets, all 110 Messier objects, bright stars) and your city, and it scores every night ahead (tonight, this week, or up to a year out) based on altitude during darkness, moonlight, and the 14-day cloud forecast. It has a draggable sky view showing where to point plus a button to just tell you what's good tonight if you don't have a target in mind... Free, no ads, no signup, works on your phone. Thought it might be useful to others here. Please let me know if you have any thoughts or suggestions for later...
