# Hygrometer vs SensorBlue

The clearest difference is rating: Hygrometer at 4.7 against SensorBlue's 3.2. Hygrometer also leads on ratings volume (6.1K vs 14) and chart position (#130 vs unranked). SensorBlue's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.

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

Hygrometer holds the better App Store score, 4.7 against 3.2. That said, the two scores are not equally well evidenced: Hygrometer has 6.1K ratings behind it against 14, 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 46% of SensorBlue's.

Hygrometer ships an update every 5 weeks, SensorBlue every 6 weeks. The most recent releases landed on October 14, 2026 and October 12, 2026 respectively.
