Graphwar II is the successor to the acclaimed Graphwar game. It is an artillery game in which you must hit your enemies using mathematical functions. The trajectory of your shot is determined by the function you wrote, and your goal is to avoid the obstacles and your teammates and hit your enemies. The game takes place in a Cartesian Plane. Graphwar II brings a modern UI, new game modes, character customization, replays, and a campaign to be played in single player mode. Graphwar II brings both an easier introduction to new players and also newer challenges to veteran players.

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 price: Ohmie at Free against Graphwar II's $4.99. Ohmie also leads on ratings volume (247 vs 3) and rating (4.5 vs 4.3). Graphwar II's advantage is review sentiment (100% vs 56%) and in-app purchases (none vs 4). On chart position and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Ohmie is free to download; Graphwar II costs $4.99 up front. Ohmie sells 4 in-app purchases, starting at $7.99 per month. Graphwar II asks for nothing beyond the download.
Ohmie holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Ohmie has 247 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Graphwar II's written reviews are positive against 56% of Ohmie's, so the app with the better star average is not the one people write more warmly about.
Graphwar II ships an update every 2 days, Ohmie every 3 days. The most recent releases landed on October 9, 2026 and October 18, 2026 respectively.
