Verdict
The clearest difference is price: Starry Map at Free against StarMap 3D's $1.99. Starry Map also leads on update cadence (every 2 weeks vs every 6 weeks). StarMap 3D's advantage is ads (none vs shown) and review sentiment (89% vs 62%). On in-app purchases, monetization model and device support there is nothing between them.
