# Dew Point Calc vs Hygrometer

The clearest difference is rating: Hygrometer at 4.7 against Dew Point Calc's 3.5. Hygrometer also leads on ratings volume (6.1K vs 15) and chart position (#117 vs unranked). Dew Point Calc's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Hygrometer sells 2 one-off in-app purchases. Dew Point Calc asks for nothing beyond the download.

Hygrometer holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Hygrometer has 6.1K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 72% of Dew Point Calc's written reviews are positive against 53% of Hygrometer's, so the app with the better star average is not the one people write more warmly about.

Dew Point Calc ships an update monthly, Hygrometer every 3 weeks. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
