Fluxmeter vs Physics Labs
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Fluxmeter
This utility app detects invisible electromagnetic fields using your device's magnetometer. It scans for alternating current waves from power lines and unshielded devices, employing a unique algorithm to isolate local magnetic flux.
- Detects electromagnetic fields
- Uses device magnetometer
- Scans for 50/60hz AC waves
- Measures local magnetic flux
- Proprietary zeroing algorithm

Measure the invisible electromagnetic fields that surround us. This utility uses your device's built in magnetometer to scan for 50/60hz alternating current waves, emanating from power lines and unshielded devices that use alternating current, such as desk fans, space heaters, or toasters. Fluxmeter uses a proprietary algorithm to "zero" out the Earth's magnetic field, allowing measurement of the local area magnetic flux only.
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. You can forward any suggestions, requests or concerns to info@grandmount.org

Verdict
The clearest difference is ads: Fluxmeter at none against Physics Labs's shown. Fluxmeter also leads on monetization model (free vs ad-supported). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
