# Hygrometer vs Surf

The clearest difference is review sentiment: Surf at 86% 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 997). On price, ads, in-app purchases and monetization model there is nothing between them.

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 997, 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 86% of Surf's.

Hygrometer ships an update every 3 weeks, Surf every 6 weeks. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
