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. Everything below is part of Ohmie Pro, an auto-renewing subscription. Details are in OHMIE PRO SUBSCRIPTION at the end. 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 • Physics: charge, electric fields, Gauss's law, potential, capacitors, circuits, magnetism and induction • 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 MOMENTUM THAT FORGIVES XP, streaks, daily quests, 28 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. OHMIE PRO SUBSCRIPTION Ohmie is free to download. The lessons, practice, circuit sims, Ask Ohmie and everything else described above require an Ohmie Pro subscription, billed monthly or yearly. The yearly plan starts with a free trial for eligible new subscribers. Prices are shown in the app before you buy. Payment is charged to your Apple Account. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it any time in your Apple Account settings.

Verdict

The call

The clearest difference is review sentiment: Thevenin at 100% against Ohmie's 48%. Thevenin also leads on ads (none vs shown) and iOS requirement (17.6 vs 26.2). Ohmie's advantage is ratings volume (331 vs 11) and rating (4.5 vs 4.3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Thevenin sells 2 in-app purchases, starting at $4.99 per month and Ohmie sells 5 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Ohmie holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Ohmie has 331 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 100% of Thevenin's written reviews are positive against 48% of Ohmie's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 days. The most recent releases landed on November 5, 2026 and November 7, 2026 respectively.
