# Physics Toolbox Sensor Suite vs Quadratic Formula Calculator

The clearest difference is ads: Physics Toolbox Sensor Suite at none against Quadratic Formula Calculator's shown. Physics Toolbox Sensor Suite also leads on update cadence (weekly vs every 9 months) and ratings volume (1.8K vs 71). On price, rating, review sentiment 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 Quadratic Formula Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Physics Toolbox Sensor Suite against 4.7 for Quadratic Formula Calculator. That said, the two scores are not equally well evidenced: Physics Toolbox Sensor Suite has 1.8K ratings behind it against 71, so its average is the more settled of the two. Written reviews are what separate them: 80% of Physics Toolbox Sensor Suite's written reviews are positive against 75% of Quadratic Formula Calculator's.

Physics Toolbox Sensor Suite ships an update weekly, Quadratic Formula Calculator every 9 months. The most recent releases landed on September 26, 2026 and June 1, 2026 respectively.
