Verdict

The call

The clearest difference is in-app purchases: 海水温ナビ at none against Room Screen's 1. 海水温ナビ also leads on update cadence (fortnightly vs every 3 months). Room Screen's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.6). On price and ads there is nothing between them.
