Electromag is an educative application in support to a high-school or university course of electromagnetism. It contains not only a memorandum of the basic equations, but it also contains approximately twenty animations illustrating the various concepts of electromagnetism. This application runs also on iPad and iPod Touch 3rd generation and later. 50 screens of electromagnetism! For teachers !! Connect your iPad with a video projector and show the animations to your students in classroom. List of covered subjects: Electrostatics: Coulomb'sLaw, Electric Field, Gauss Theorem, Electric Potential, Capacitance. Electric Current: Current and Resistance, Circuits. Magnetism: Magnetic Field, Magnetic Fields Due to Currents, Electromagnetic Induction, Inductance. Electromagnetism: Maxwell Equations, Wave Equation. Physical Constants. Each section contains at least one animation of which some in 3D. List of animations: - Coulomb's law, - Electric field lines, - Movement of a charge in electric field, - Electric dipole, - Lead-acid battery, - Torque on a current loop (in 3D), - Charge in magnetic field, - Cyclotron, - Induction field due to a current in a long straight wire (in 3D), - Generator (in 3D).
Relativistic Space
This educational tool simulates the behavior of space and time at high speeds. Developed as part of a master's dissertation, it focuses on relativistic effects without considering acceleration.
- Relativistic velocity simulation
- Space-time behavior visualization
- Pedagogical tool
- Master's dissertation project

This simple simulator shows how space and time behave at relativistic velocities. It was developed as a pedagogical tool as part of a master's dissertation at the Federal University of Espírito Santo. Thus, it does not take into account the acceleration effects of the spacecraft. It was developed in a partnership between Prof Thiéberson Gomes (UFES), Prof Flávio Gimenes (UFES) and student Luiz Henrique Gobbi, with computational support Rodrigo Marques.

Verdict
The clearest difference is review sentiment: Relativistic Space at 100% against Electromag's 45%. Relativistic Space also leads on price (Free vs $1.99) and iOS requirement (13.0 vs 18.6). Electromag's advantage is rating (5.0 vs 3.0) and update cadence (every 9 months vs every 75 months). On ratings volume, ads, in-app purchases and device support there is nothing between them.

Relativistic Space is free to download; Electromag costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Electromag holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 2 and 2 respectively. Written reviews complicate that: 45% of Electromag's written reviews are positive against 100% of Relativistic Space's, so the app with the better star average is not the one people write more warmly about.
Electromag ships an update every 9 months, Relativistic Space every 75 months. The most recent releases landed on September 29, 2026 and October 7, 2026 respectively.
