# Magnetometer / Gaussmeter vs Physics Toolbox Sensor Suite

The clearest difference is price: Physics Toolbox Sensor Suite at Free against Magnetometer / Gaussmeter's $0.99. Physics Toolbox Sensor Suite also leads on review sentiment (81% vs 50%) and update cadence (weekly vs every 40 months). Magnetometer / Gaussmeter's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.7). On ads and device support there is nothing between them.

Physics Toolbox Sensor Suite is free to download; Magnetometer / Gaussmeter costs $0.99 up front. Physics Toolbox Sensor Suite sells 1 one-off in-app purchase. Magnetometer / Gaussmeter asks for nothing beyond the download.

Magnetometer / Gaussmeter holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Physics Toolbox Sensor Suite has 1.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Magnetometer / Gaussmeter's written reviews are positive against 81% of Physics Toolbox Sensor Suite's, so the app with the better star average is not the one people write more warmly about.

Magnetometer / Gaussmeter ships an update every 40 months, Physics Toolbox Sensor Suite weekly. The most recent releases landed on October 2, 2026 and October 16, 2026 respectively.
