Sensor toolbox makes the most of all the sensors in your smartphone. With a user-friendly interface and easy to read layout, Sensor Multitool - Toolbox allows you to collect data in real time for any and all sensors on your phone. Convert the data into easy to read graphs with a detailed readout from each sensor. This app contains everything you need: an accelerometer, gyroscope, GPS Data, barometer, decibel meter, metal detector, compass, and much more. This app follows all material design guidelines, meaning the app is clean and simple to use This app uses intuitive graphs to create clean, orderly graphs of all data collected.
Magna
Visualize magnetic fields in real space using your device's magnetometer and ARKit. This app overlays magnetic field data onto your camera view, ideal for STEM education and research. Explore real-world magnetic sources with color-coded visualizations.
- AR magnetic field visualization
- Internal magnetometer data integration
- 3D mapping with ARKit
- Color-coded magnitude spheres
- Compass direction display
- Adjustable settings and color key

This app combines the data collected by the internal magnetometer with the three-dimensional mapping of ARKit to plot magnetic fields in real space superimposed upon the camera view. Useful for students and teachers in science, technology, engineering, and math (STEM) education and academic or industrial researchers, this app helps users to visualize magnetic fields based upon real sources—not prepared computational models—without the use of external sensors. The actual total magnitude of the magnetic field at real points in space can be visualized with color-coded spheres to see changes in magnitude. A menu allows the user to learn more about the operating principles of the magnetometer, display compass directions in the field of view, and change settings to display/remove magnetic field values and modify the color key.

Verdict
The clearest difference is review sentiment: Magna at 100% against Sensors Toolbox's 53%. Magna also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 7 months). Sensors Toolbox's advantage is rating (4.2 vs 3.5) and ratings volume (134 vs 8). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Sensors Toolbox holds the better App Store score, 4.2 against 3.5. That said, the two scores are not equally well evidenced: Sensors Toolbox has 134 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 53% of Sensors Toolbox's written reviews are positive against 100% of Magna's, so the app with the better star average is not the one people write more warmly about.
Sensors Toolbox ships an update every 7 months, Magna every 3 weeks. The most recent releases landed on October 16, 2026 and October 9, 2026 respectively.
