# Clinometer+ vs OrthoMeasure

The clearest difference is review sentiment: OrthoMeasure at 100% against Clinometer+'s 48%. OrthoMeasure also leads on in-app purchases (none vs 1) and rating (5.0 vs 4.5). Clinometer+'s advantage is ratings volume (1K vs 2). On price, ads, device support and iOS requirement there is nothing between them.

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

OrthoMeasure 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 2, 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 OrthoMeasure's.
