Relativistic Space vs Ohm Law
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
Ohm Law
Read full descriptionHide full description
The invention of electricity is one of the greatest in human history, providing powerful mechanical energy, diverse communication and presentation methods, and intelligent information processing and control technologies. Ohm's Law and Kirchhoff's Voltage and Current Laws are fundamental, essential for beginners. This app demonstrates these laws, allowing users to connect batteries, bulbs, rheostats, ammeters, and voltmeters to observe current and voltage in series, parallel, and combined circuits. Suitable for students, electrical enthusiasts, physics lovers, and educators, it also offers leisure fun: watching old tungsten bulbs light up, feeling warm flickering light, measuring with traditional meters, and experimenting with shorts. Main features: 1. Batteries, bulbs, rheostats, and wires: Connect with red or black wires. Bulb brightness depends on current. 2. Voltmeter: Measures voltage across any circuit, with 3V and 15V ranges. 3. Ammeter: Measures current in series with any circuit, with 0.6A and 3A ranges. 4. Magnifier: Touch the screen (not rheostat slider) to zoom in on terminal positions or meter readings. 5. Circuit connections: Freely connect components in series, parallel, or combinations, following Ohm's and Kirchhoff's Laws. 6. Shorts: Overheated wires glow red in short circuits.

Verdict
The clearest difference is price: Relativistic Space at Free against Ohm Law's $1.99. Relativistic Space also leads on iOS requirement (13.0 vs 15.6). Ohm Law's advantage is update cadence (every 2 months vs every 75 months). On ads, in-app purchases and device support there is nothing between them.
