# Protractor+ vs OrthoMeasure

The clearest difference is review sentiment: OrthoMeasure at 100% against Protractor+'s 15%. OrthoMeasure also leads on rating (5.0 vs 4.1) and in-app purchases (none vs 1). Protractor+'s advantage is ratings volume (10K vs 2). On price, ads, device support and iOS requirement there is nothing between them.
