# Compass Pro vs Pressure Altimeter

The clearest difference is rating: Compass Pro at 4.4 against Pressure Altimeter's 2.3. Compass Pro also leads on ratings volume (12 vs 3). Pressure Altimeter's advantage is in-app purchases (none vs 1) and review sentiment (67% vs 50%). On ads there is nothing between them.

Compass Pro costs $2.99 and Pressure Altimeter $0.99 up front. Compass Pro sells 1 one-off in-app purchase. Pressure Altimeter asks for nothing beyond the download.

Compass Pro holds the better App Store score, 4.4 against 2.3. Both are backed by a comparable volume of ratings — 12 and 3 respectively. Written reviews complicate that: 50% of Compass Pro's written reviews are positive against 67% of Pressure Altimeter's, so the app with the better star average is not the one people write more warmly about.

Compass Pro ships an update every 22 months, Pressure Altimeter every 9 months. Both last shipped on November 1, 2026.
