Verdict

The call

The clearest difference is review sentiment: Surf at 87% against Hygrometer's 53%. Surf also leads on rating (4.9 vs 4.7) and iOS requirement (15.1 vs 17.0). Hygrometer's advantage is update cadence (every 3 weeks vs every 6 weeks) and ratings volume (6.1K vs 991). On price, ads, in-app purchases and monetization model there is nothing between them.
