A short lesson picks up right where you left off.

Answer real questions and fix live circuits by hand.

Earn XP, level up, and come back tomorrow.
Hands-on from lesson one
Tap the break in the loop. Fix the fault. Watch the lamp light up — on a circuit that actually responds.
Ohmie World is a small town inside the app: light your first LED on a real breadboard bench, then duel the Copper Trail's three trainers.

Explore holds your streak, the weekly leaderboard, every topic, and the review queue for anything you missed.
Built to bring you back
Every lesson banks XP and keeps your streak alive.

Voltage, current, capacitors, op-amps — from your first spark to your own amplifier design.

02

How Chips Speak: how electricity carries information at all — then logic gates you predict before they fire.
The Logic Lab becomes a 3D world built into the app: fly it, land at ten level walls and build working circuits, from a single lamp up to a latch and a clock.

Inside the transistor: holes, doping, and the 1947 Bell Labs breakthrough — rebuilt bench by bench, by you.
04
103 lessons
Where code meets copper: pins, analog reads, interrupts, and the sensors that feel the world.
05
Python and C++ tracks
Two tracks: Python from zero, and Arduino C++ from your first Hello, World! to an autonomous robot.

48 lessons
From breadboard to board: lay out real PCBs in OhmieCAD, the built-in board editor.

No. Every circuit is simulated and playable right in the app — though builds are real enough to copy onto your desk.
Yes. Ohmie starts at "What is electricity?" and builds up one short lesson at a time.
Seven subjects — Electronics, Digital Circuits, Semiconductors, Embedded Systems, Programming, PCB Design and Robotics — take you from Ohm's law to what's happening inside a transistor, then on to IMUs, sensor fusion and SLAM. It's the same lesson format the whole way; the ideas just get bigger.
Ask Ohmie. Every question has a built-in hint and explanation, and signed-in subscribers can ask Ohmie follow-up questions right there on the question.
English, Spanish, Czech and Brazilian Portuguese. Lesson narration stays English for now.
Yes. Yearly starts with a 7-day free trial — cancel before it ends and nothing is charged. Either plan can be cancelled any time from the App Store.
