gravity detector vs Pic2Mag
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
gravity detector
Measure the G-force experienced in elevators or planes and compare it to planetary gravity. Record environmental photos, videos, and coordinates to save for later reference, and view G-values on a map.
- Measure G-force in real-time
- Compare G-force to planetary gravity
- Record environmental photos and videos
- Save location coordinates
- View G-values on a map

While on an elevator or plane. You can check the G value you're experiencing, and see which planet's gravity is it equivalent to. Even more, you can measure the earth gravity around your place, take photo/video of the environment, record the coordinate, and save it for future reference. And you can check the G values in map. Note: Please use this app only inside Earth. And the G value is approximate.
Pic2Mag
Visualize magnetic and electric fields by drawing magnets or charges. This educational tool helps students understand physics concepts by displaying field lines and voltage potentials. It offers a free, ad-free learning experience for iOS devices.
- Draw magnets to visualize magnetic fields
- Draw charges to visualize electric fields
- Magnetostatic and Electrostatic modes
- Field line and voltage potential plotting
- Caches results for faster processing
- Ad-free learning experience

The user draws the magnets and the Pic2Mag program draws the magnetic fields. The Field Calculator program now has a Magnetostatic mode, and an Electrostatic mode to plot either magnetic fields or electric fields. The program designed to help students learn Magnetic fields and Electric fields. You can draw magnets and look at the magnetic field, or you can draw electric charges and look at the electric voltage field. The best free magnetic science program you can download! No advertisements, it's just all app. The app can process most images in just a few minutes. The app caches it's results so the more that you use it, the faster the program processes images. Red pixels represent magnets with a North pole surface facing the observer, and Blue pixels represent magnets with a South pole surface facing the observer. Pink pixels represent positive electric charges, and Dark Purple pixels represent negative electric charges
