# TempPro Sensor vs Absolute Humidity

The clearest difference is in-app purchases: TempPro Sensor at none against Absolute Humidity's 2. TempPro Sensor also leads on ads (none vs shown) and ratings volume (11K vs 2). Absolute Humidity's advantage is review sentiment (80% vs 46%). On price, update cadence and device support there is nothing between them.

TempPro Sensor holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: TempPro Sensor has 11K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 46% of TempPro Sensor's written reviews are positive against 80% of Absolute Humidity's, so the app with the better star average is not the one people write more warmly about.

TempPro Sensor ships an update every 2 months, Absolute Humidity every 5 weeks. The most recent releases landed on September 25, 2026 and September 13, 2026 respectively.
