About

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.

Highlights
  • AR magnetic field visualization
  • Internal magnetometer data integration
  • 3D mapping with ARKit
  • Color-coded magnitude spheres
  • Compass direction display
  • Adjustable settings and color key
Features
Read full description

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.

About

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.

Highlights
  • 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 call

The clearest difference is ads: Magna at none against Physics Labs's shown. Magna also leads on monetization model (free vs ad-supported) and iOS requirement (13.0 vs 15.6). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
