What's the best Android app for planning my stargazing sessions around specific celestial events?

Stellarium Mobile is an exceptionally detailed planetarium application designed specifically for serious astronomy enthusiasts and casual stargazers. For planning around celestial events like meteor showers, planetary conjunctions, or eclipses, its primary utility lies in the time simulation feature. Users can fast-forward or rewind time to see exactly how the night sky will appear from their specific location at any future or past moment. This allows for verifying visibility windows for events like the Perseid meteor shower's radiant point rising or checking when Jupiter's moons will be visible. The app renders over 600,000 stars and includes detailed illustrations of constellations, along with realistic atmospheric effects. A common use case involves setting the app's time to an upcoming Saturday night to preview where to point a telescope to catch Saturn's rings or to plan a photography session for the Milky Way's core. Reviews indicate the star catalog's depth is a major strength, though some note that the wealth of information can feel overwhelming initially without using the search and filter functions. A minor but noted imperfection is the occasional promotional prompt for the paid version, which some long-term users find interrupts the immersive experience. The free version is remarkably comprehensive, while the paid upgrade removes ads and adds telescope control features.
