# Physics Toolbox Sensor Suite vs TrueEntropy

The clearest difference is in-app purchases: TrueEntropy at none against Physics Toolbox Sensor Suite's 1. TrueEntropy also leads on iOS requirement (12.0 vs 16.0). Physics Toolbox Sensor Suite's advantage is update cadence (weekly vs every 41 months) and ratings volume (1.8K vs 11). 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. TrueEntropy asks for nothing beyond the download.

Physics Toolbox Sensor Suite holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Physics Toolbox Sensor Suite has 1.8K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 81% of Physics Toolbox Sensor Suite's written reviews are positive against 67% of TrueEntropy's.

Physics Toolbox Sensor Suite ships an update weekly, TrueEntropy every 41 months. The most recent releases landed on October 18, 2026 and October 9, 2026 respectively.
