# Physics Toolbox Sensor Suite vs Steam Pad

The clearest difference is rating: Physics Toolbox Sensor Suite at 4.7 against Steam Pad's 3.7. Physics Toolbox Sensor Suite also leads on ratings volume (1.8K vs 3) and review sentiment (80% vs 67%). Steam Pad's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (9.0 vs 16.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Physics Toolbox Sensor Suite sells 1 one-off in-app purchase and Steam Pad sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Physics Toolbox Sensor Suite holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Physics Toolbox Sensor Suite has 1.8K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 80% of Physics Toolbox Sensor Suite's written reviews are positive against 67% of Steam Pad's.

Physics Toolbox Sensor Suite ships an update weekly, Steam Pad every 9 days. The most recent releases landed on September 24, 2026 and June 1, 2026 respectively.
