magnetoboy vs Physics Labs
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
magnetoboy
This utility app uses your device's magnetometer to measure and visualize magnetic fields. Detect ferromagnetic materials, observe field changes, and even use it for locating hidden objects by attaching a magnet. The app provides visual graphs and optional vibration feedback for strong fields.
- Measure magnetic field strength
- Visualize magnetic fields with graphs
- Detect ferromagnetic materials
- Vibration feedback for strong fields
- Useful for locating hidden objects
- Observe Earth's magnetic field

Use your device's magnetometer, and read out the magnetic field (micro teslas). You can observe and examine the magnetic fields around you. You will find that certain materials change the magnetic field. Such as Iron, magnets, nails, speakers, some metals, electronics, the earth, and more. This may be used to find things, that are ferromagnetic. Change the feedback level to get a vibration when some strong magnetic field is nearby. Observe the graph to visualize the fields around you. Can be used in construction: by attaching a magnet to something behind a wall and use the app to locate the target. The magnetometer, is usually used in navigation to detect the magnetic fields of the earth. The phone must not be in mute for the sound to work.
Physics Labs
This app uses your device's sensors to measure various physical quantities like acceleration, magnetic fields, and sound levels. View data in coordinates or scalar magnitude, and export it to Excel for analysis. It's a digital lab for your phone.
- Measure acceleration, magnetic fields, and sound levels
- View data in X, Y, Z coordinates or scalar magnitude
- Export sensor data to Excel for analysis
- Eliminate gravity from acceleration measurements
- Measure atmospheric pressure

Physics Lab is all-in-one Sensor app which let you know physical entities around you like acceleration, magnetic fields, light intensity, sound decibel and much more... Physics Lab measures physical parameters by using your device sensors which typical device contain bunch of those sensors! Application give output in high precision with short intervals based on your sensor's capabilities. In Physics Lab, you can observe physical data in coordinates (X-axis, Y-axis, Z-axis) or in scalar magnitude. If you want, you can export sensor data into Excel by one click! Using export to excel feature you can obtain statistical information about your measurement. Physical quantities that can be measured Physics Lab: * Accelerometer: Measuring acceleration around your device. Output in m/s2 for x, y and z axes. Also, you can eliminate gravity from your measurements by one click and see real acceleration. * Magnetometer: Measuring magnetic field around your device. Output in µT for x, y and z axes. * Gyroscope: Measure angular inclination in x, y and z axes. Output in degree (°) * Luxmeter: COMING SOON * Barometer: Measure atmospheric pressure. Output in bar. * Noisemeter: Measure loudness around you. Output in dB. If you like our application, you can give us 5 stars.

Verdict
The clearest difference is ads: magnetoboy at none against Physics Labs's shown. magnetoboy also leads on monetization model (free vs ad-supported) and iOS requirement (12.0 vs 15.6). Physics Labs's advantage is update cadence (every 2 weeks vs monthly). On price, review sentiment, in-app purchases and device support there is nothing between them.
