Verdict
The clearest difference is in-app purchases: count at none against Starry Map's 7. count also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.0). Starry Map's advantage is update cadence (every 2 weeks vs every 6 months). On price and device support there is nothing between them.
