# zenith Smart vs TempPro Sensor

The clearest difference is rating: TempPro Sensor at 4.7 against zenith Smart's 3.0. TempPro Sensor also leads on ratings volume (13K vs 4) and iOS requirement (13.1 vs 15.6). zenith Smart's advantage is update cadence (every 2 weeks vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

TempPro Sensor holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: TempPro Sensor has 13K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of zenith Smart's written reviews are positive against 47% of TempPro Sensor's, so the app with the better star average is not the one people write more warmly about.

zenith Smart ships an update every 2 weeks, TempPro Sensor every 2 months. The most recent releases landed on November 13, 2026 and November 14, 2026 respectively.
