# Physics Toolbox Sensor Suite vs µMagnetometer

The clearest difference is review sentiment: Physics Toolbox Sensor Suite at 80% against µMagnetometer's 23%. Physics Toolbox Sensor Suite also leads on price (Free vs $1.99) and update cadence (weekly vs every 4 months). µMagnetometer's advantage is in-app purchases (none vs 1) and iOS requirement (11.0 vs 16.0). On ads and device support there is nothing between them.

Physics Toolbox Sensor Suite is free to download; µMagnetometer costs $1.99 up front. Physics Toolbox Sensor Suite sells 1 one-off in-app purchase. µMagnetometer asks for nothing beyond the download.

Physics Toolbox Sensor Suite holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Physics Toolbox Sensor Suite has 1.8K ratings behind it against 67, 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 23% of µMagnetometer's.

Physics Toolbox Sensor Suite ships an update weekly, µMagnetometer every 4 months. The most recent releases landed on September 24, 2026 and August 29, 2026 respectively.
