Magnetometer / Gaussmeter vs Physics Toolbox Sensor Suite
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Magnetometer / Gaussmeter
Transforms your device into a magnetic field strength meter. Detect residual magnetism in steel objects, measure magnet strength, and analyze magnetic fields on three axes. Useful for various applications including material assessment and component analysis.
- Magnetic Strength Meter (DC Gauss Meter)
- Detect residual magnetism in steel
- Measure magnetism on three axes (x,y,z)
- Switchable units: Tesla, Gauss
- 1 mG (0.1μT) Resolution
- Check magnet strength

This App turn your device into a Magnetic Strength Meter (DC Gauss Meter). DC magnetic fields can develop in many steel or iron objects if they have been exposed to magnetic fields, current, or friction. This App detects residual magnetism in steel parts quickly and accurately. Simply place the device edge near or against the object being tested, to have a reading representing the magnetism in the object at that site as well as polarity. Will also possible to verify thoroughness of de-magnetizing. Check out your car, bed frame, desk furniture or any other metal objects you spend time with. Can also be used to check the strength of magnets. Features: - Detect the strength of Magnetic force fields on all three axis’s (x,y,z) - Switchable units: Tesla, Gauss - 1 mG (0.1μT) Resolution Applications: - Assessment of magnetic materials. - Analysis of magnetic circuits and components - Measurement of residual magnetis - Measure stray and leakage fields - Measurement of absolute, and differential fields - Testing, sorting, classifying magnets - DC and AC motor testing - Relay and solenoid test - Loudspeaker test Note: the measure is never 0 because there is the Earth's magnetic field

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
