Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Hygrometer sells 2 one-off in-app purchases and Surf sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Surf holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Hygrometer has 6.1K ratings behind it against 991, so its average is the more settled of the two. Written reviews point the same way: 53% of Hygrometer's written reviews are positive against 87% of Surf's.
Hygrometer ships an update every 3 weeks, Surf every 6 weeks. Both last shipped on October 21, 2026.
