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. 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 • Circuits — charge, current, voltage, Ohm's law, series & parallel, your first LED circuit • Op-amps, components, transistors, digital logic, power • Embedded systems — GPIO, PWM, ADC, interrupts, serial protocols • Robotics — sensors, motors, PID control, build a line-following racer MOMENTUM THAT FORGIVES XP, streaks, daily quests, and a mascot named Ohmie who's on your side. Streaks are forgiving — life happens. No ads. Your progress stays on your device.

Verdict
The clearest difference is ads: Embedded Systems+ at none against Ohmie's shown. Embedded Systems+ also leads on rating (5.0 vs 4.6) and iOS requirement (17.0 vs 26.2). Ohmie's advantage is update cadence (every 3 days vs every 5 weeks) and ratings volume (146 vs 1). On price, in-app purchases, monetization model 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
Both are free to download. Embedded Systems+ sells 6 in-app purchases, starting at $9.99 per month and Ohmie sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
Embedded Systems+ holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Ohmie has 146 ratings behind it against 1, so its average is the more settled of the two.
Embedded Systems+ ships an update every 5 weeks, Ohmie every 3 days. The most recent releases landed on September 17, 2026 and September 30, 2026 respectively.
