# Hygrometer vs Mountain

The clearest difference is review sentiment: Mountain at 74% against Hygrometer's 53%. Mountain also leads on rating (4.9 vs 4.7) and iOS requirement (15.1 vs 17.0). Hygrometer's advantage is ratings volume (6.1K vs 707). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Hygrometer sells 2 one-off in-app purchases and Mountain sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Mountain 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 707, 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 74% of Mountain's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
