VoltSim is a realtime electronic circuit simulator like Multisim, SPICE, LTspice, Altium or Proto for circuit design with a better user experience. VoltSim is a complete circuit app in which you can design circuits with various components and simulate an electric or digital circuit. During simulation you can check voltage, current and many other variables. Check signals on multichannel oscilloscope or multimeter and tune your circuit in real time! You can also use VoltSim as logic circuit simulator and perform digital electronic analysis! This app will help you visualize how the voltage varies across the circuit and how current flows through it. T&C: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Pass circuits. 3 minutes a day. Ohmie teaches electronics the way you'd learn a language: short, game-like lessons you actually solve, not paragraphs you skim. Lessons are read aloud, so your eyes stay on the circuit. REAL PRACTICE • Live circuit sims: stack battery cells, dim an LED, watch current respond to resistance • Build schematics by dragging real components into place • Decode resistor color bands, spot the broken circuit, order the steps • Miss a question? It comes back in Practice until it sticks. That's the method, not a penalty. LEARN THE FULL PATH • Electronics: charge, current, voltage, Ohm's law, series and parallel, capacitors, power, analog, then transistors, logic gates and an 8-bit computer you can run, pause and step through • Embedded systems: GPIO, timers, PWM, ADC, interrupts, serial protocols, build a device • Robotics: sensors, motors, PID control, build a line-following racer • PCB design: schematics, layout, routing, production • Programming: Python, and C++ for Arduino EXPLORE OHMIE WORLD Walk into Copper Town, take on the trainers in the forest, wire the town's circuit on a breadboard, and face other learners in the Arena. MOMENTUM THAT FORGIVES XP, streaks, daily quests, 30 badges to earn, skins to unlock, leaderboards, and a mascot named Ohmie who reacts to every answer and is on your side. Streaks are forgiving. Life happens. Stuck? Ask Ohmie and get a hint in plain words. No ads. Learn in English, Spanish or German. Sign in to keep your progress across devices.

Verdict
The clearest difference is ads: Circuit Simulator at none against Ohmie's shown. Circuit Simulator also leads on review sentiment (77% vs 56%) and rating (4.7 vs 4.5). Ohmie's advantage is update cadence (every 3 days vs every 6 weeks) and chart position (#79 vs unranked). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
