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 update cadence: Robotics U at every 11 days against Circuitry's every 4 months. Robotics U also leads on review sentiment (67% vs 51%) and iOS requirement (9.0 vs 12.0). Circuitry's advantage is rating (3.9 vs 3.6) and ratings volume (155 vs 16). On price, ads, 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. Neither carries in-app purchases, so what you see is what you pay.
Circuitry holds the better App Store score, 3.9 against 3.6. That said, the two scores are not equally well evidenced: Circuitry has 155 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 67% of Robotics U's written reviews are positive against 51% of Circuitry's, so the app with the better star average is not the one people write more warmly about.
Robotics U ships an update every 11 days, Circuitry every 4 months. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
