# Hygrometer vs Thermometer

Hygrometer and Thermometer both sit at 4.7 stars, but that hides the real split: 81% of Thermometer's written reviews are positive against 53% of Hygrometer's. Thermometer also leads on iOS requirement (15.6 vs 17.0). Hygrometer's advantage is ratings volume (6.1K vs 28) and chart position (#143 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Hygrometer sells 2 one-off in-app purchases and Thermometer sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Hygrometer against 4.7 for Thermometer. That said, the two scores are not equally well evidenced: Hygrometer has 6.1K ratings behind it against 28, so its average is the more settled of the two. Written reviews are what separate them: 53% of Hygrometer's written reviews are positive against 81% of Thermometer's.

Hygrometer ships an update every 2 months, Thermometer every 5 weeks. Both last shipped on September 22, 2026.
