Thevenin AI is the fastest way to solve and understand STEM problems. Scan any problem and get a complete, step-by-step solution in seconds. Built for real STEM coursework — circuits, physics, chemistry, and more — not generic math. No guessing. No skipped steps. Just clear solutions you can follow. What you can do: Scan any STEM problem instantly Capture problems from textbooks, homework, labs, or handwritten notes. Thevenin AI detects equations, diagrams, circuits, structures, and values with high accuracy. See full step-by-step solutions Every solution is broken into structured, numbered steps so you can understand exactly how the answer is derived. Solve across STEM subjects Circuits (DC and AC, Thevenin and Norton equivalents, nodal and mesh analysis, op-amps, BJTs), physics (kinematics, forces, energy, electromagnetism, thermodynamics), chemistry (stoichiometry, equilibrium, reaction balancing, thermochemistry), and more. Understand, not memorize Go beyond answers. Learn the method behind each solution so you can apply it on exams. Built for real STEM students and engineers Designed around actual coursework. Works on messy diagrams, lab sketches, chemical structures, and real exam-style problems. Why Thevenin: Saves hours on assignments Removes trial and error Improves conceptual understanding Helps you prepare for exams faster Works when solution manuals don't Speed and performance: Full solution with steps in under 15 seconds for most problems High-accuracy recognition across equations, diagrams, and circuits Handles complex, multi-step problems Who it's for: STEM students and engineers Anyone taking circuits, physics, chemistry, electronics, or systems courses Students who want to actually understand the material, not just get answers Start solving Scan your problem Get the full solution Understand every step Download Thevenin, the AI for solving STEM, and turn any problem into a complete solution instantly.

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 review sentiment: Thevenin at 100% against Ohmie's 57%. Thevenin also leads on ads (none vs shown) and iOS requirement (17.6 vs 26.2). Ohmie's advantage is rating (4.5 vs 4.2) and ratings volume (209 vs 10). On price, update cadence, in-app purchases and monetization model 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. Thevenin sells 2 in-app purchases, starting at $4.99 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.
Ohmie holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Ohmie has 209 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 100% of Thevenin's written reviews are positive against 57% of Ohmie's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 days. The most recent releases landed on October 17, 2026 and October 14, 2026 respectively.
