# Clinometer+ vs Survey Compass

The clearest difference is review sentiment: Survey Compass at 100% against Clinometer+'s 48%. Survey Compass also leads on in-app purchases (none vs 1) and rating (5.0 vs 4.5). Clinometer+'s advantage is ads (none vs shown) and ratings volume (1K vs 3). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Clinometer+ sells 1 one-off in-app purchase. Survey Compass asks for nothing beyond the download.

Survey Compass holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Clinometer+ has 1K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 48% of Clinometer+'s written reviews are positive against 100% of Survey Compass's.

Clinometer+ ships an update every 2 months, Survey Compass weekly. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
