Compass Map Barometer holds the better App Store score, 4.4 against 4.0.

Written reviews complicate that: 38% of Compass Map Barometer's written reviews are positive against 56% of Sensor's, so the app with the better star average is not the one people write more warmly about.
Compass Map Barometer ships an update every 7 months, Sensor every 2 months. The most recent releases landed on October 7, 2026 and September 29, 2026 respectively.
