Meet Ohmie. Learn real electronics, 3 minutes a day.
Real problems, not paragraphs — the way you'd learn a language.
How Ohmie works
Three minutes, three moves — that's the whole loop.
Pick today's rep
A 3-minute lesson picks up right where you left off.
Solve, don't watch
Answer real questions and fix live circuits by hand.
Keep the streak
Earn XP, level up, and come back tomorrow.
This is not another video course
You don't watch electronics. You solve it.
Tap the break in the loop. Fix the fault. Watch the lamp light up — on a circuit that actually responds.
It starts at "what is electricity?" and ends at robot navigation.
Five sections, each one built on the last. Same three minutes a day the whole way up.
-
01
Circuits I
Voltage, current, resistance. Ohm's law until it's muscle memory.
-
02
Circuits II
Capacitors, dividers, and the 555 timer — the parts real designs are made of.
-
03
Semiconductors
Inside the transistor: holes, doping, and the PN junction that makes modern electronics possible.
-
04
Microcontrollers
Pins, analog reads, interrupts — write the code that drives the circuit.
-
05
Robotics
IMUs, sensor fusion, and SLAM — how a robot figures out where it is.
No prerequisites. Start at 01 and keep going.
Learn by solving
Every lesson is real questions with an instant explanation — plus +10 XP when you nail it.
Everything, one tap away
Explore holds your streak, the weekly leaderboard, every topic, and the newest releases — plus the review queue for anything you missed.
Build it for real
Wire it. Code it. Watch it work — every step playable, every circuit real enough to copy onto your desk.
What does Ohmie include?
Built to bring you back
Streaks, levels, and a Daily Charge that make 3 minutes stick.
- Level up to Circuit Apprentice and beyond.
- A Daily Charge every day — five questions, +15 XP.

Questions, answered
Do I need any hardware or a breadboard?
No. Every circuit is simulated and playable right in the app — though builds are real enough to copy onto your desk.
Is it good for total beginners?
Yes. Ohmie starts at "What is electricity?" and builds up 3 minutes at a time.
How far does it actually go?
Further than most people expect. Five sections — Circuits I, Circuits II, Semiconductors, Microcontrollers, 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.
Can I just experiment without a lesson?
Yes — Circuit Lab is an open bench. Wire up whatever you want and watch it behave, with nothing to get right and no XP on the line.
What if I get stuck on a question?
Ask Ohmie. Tap into a chat right there on the question and Ohmie walks you through it step by step, as many times as you need — it's built into your subscription, and it's for ages 13 and up.
Can I design a real circuit board?
Yes — PCB Studio lets you draw a schematic, place the parts, route the copper, run the design checks, and spin the finished board in 3D. Same workflow as the desktop tools engineers actually use.
Can I cancel anytime?
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.
Your first circuit is 3 minutes away.
