Welcome to Circuitry - the world's first and only 3D circuit builder! INSANELY FAST Circuitry uses an optimized, GPU-accelerated network analysis algorithm that will blow your mind. It can calculate the voltages and currents of even the largest circuits in the blink of an eye - an insanely fast blinking eye! SUPER DUPER EASY TO USE While most circuit simulators are stuck in the stone age when it comes to usability, Circuitry takes you on a time-travel journey to the future. Its' 3D interface and intuitive controls will instantly feel familiar - no lengthy tutorials required. DOCUMENT-BASED Every circuit you build in Circuitry is a file. That way, they integrate perfectly into your existing files and can be used exactly the same way: you can duplicate and modify them, share them, and they are available to you on all your devices. HOW TO USE: 1. Place components by dragging from the toolkit to the canvas. 2. Connect components by tapping the sides of the components in cabling mode. 3. Delete or modify components by long pressing on them. AVAILABLE COMPONENTS: - Resistor - Voltage source - Light bulb

Verdict
The clearest difference is review sentiment: Thevenin at 100% against Circuitry's 51%. Thevenin also leads on update cadence (every 3 days vs every 4 months) and rating (4.3 vs 3.9). Circuitry's advantage is in-app purchases (none vs 2) and ratings volume (156 vs 11). On price and ads 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. Circuitry asks for nothing beyond the download.
Thevenin holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Circuitry has 156 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 51% of Circuitry's written reviews are positive against 100% of Thevenin's.
Circuitry ships an update every 4 months, Thevenin every 3 days. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
