# Physics Toolbox Sensor Suite vs Privus

The clearest difference is rating: Physics Toolbox Sensor Suite at 4.7 against Privus's 3.3. Physics Toolbox Sensor Suite also leads on ratings volume (1.8K vs 3) and review sentiment (81% vs 67%). Privus's advantage is in-app purchases (none vs 1) and iOS requirement (12.1 vs 16.0). On price, ads and device support there is nothing between them.

Both are free to download. Physics Toolbox Sensor Suite sells 1 one-off in-app purchase. Privus asks for nothing beyond the download.

Physics Toolbox Sensor Suite holds the better App Store score, 4.7 against 3.3.
