Verdict

The call

The clearest difference is in-app purchases: Armpit at none against Nautiline's 1. Armpit also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 88%). Nautiline's advantage is ratings volume (84 vs 4) and iOS requirement (17.0 vs 26.0). On price, update cadence and ads there is nothing between them.
