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

Verdict
The clearest difference is price: Pic2Mag at Free against Pendulum Lab's $0.99. Pic2Mag also leads on in-app purchases (none vs 1) and iOS requirement (8.0 vs 15.0). Pendulum Lab's advantage is update cadence (every 5 weeks vs every 31 months). On ads and device support there is nothing between them.
