# SeeLevel vs Clinometer+

The clearest difference is price: Clinometer+ at Free against SeeLevel's $0.99. Clinometer+ also leads on rating (4.5 vs 3.8) and ratings volume (1K vs 18). SeeLevel's advantage is in-app purchases (none vs 1) and review sentiment (67% vs 48%). On ads and device support there is nothing between them.

Clinometer+ is free to download; SeeLevel costs $0.99 up front. Clinometer+ sells 1 one-off in-app purchase. SeeLevel asks for nothing beyond the download.

Clinometer+ holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Clinometer+ has 1K ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 67% of SeeLevel's written reviews are positive against 48% of Clinometer+'s, so the app with the better star average is not the one people write more warmly about.

SeeLevel ships an update every 6 months, Clinometer+ every 2 months. Both last shipped on October 13, 2026.
