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

iCircuit 3D gives you an endless virtual workbench to design, build, and test electronics projects in 3D. It combines the robust real-time, always-on simulation engine of iCircuit with modern 3D rendering and physics on iOS and macOS. Do not let the availability of physical parts limit your creativity. Choose from an expansive library of 150+ physically and electronically simulated parts and over 1,000 reference boards to plan layouts, wire circuits, test ideas, and iterate fast. It also includes the full standard component library from the original iCircuit, so you can switch between realistic parts and symbolic circuit elements whenever you want. When powered, LEDs light up realistically, DC motors spin, and speakers make noise. Watch current flow along your simulated wires. See pinouts and color codes directly on components. Tap any part to view live values like voltage and current, then change parameters instantly. If you miswire something or overstress a component, magic smoke will billow from the point of failure so you can quickly diagnose and fix the problem. Add reference photos to the environment, import your own 3D models to mount projects onto, or use Blocks to build enclosures, panels, and simple structures. FEATURES • Tons of resistors, capacitors, and LEDs • Multiple breadboards and wiring elements • Diodes, BJTs, MOSFETs • DC power supplies • Waveform generators (AC, square, sawtooth) • Batteries (AA, AAA, 18650, coin cells, and more) • Switches (SPST, SPDT) • Buzzers and speakers • DC motors and servos • Programmable Arduino elements • The full symbolic iCircuit library (standard components included) • 1,000+ reference circuit boards for layout planning (not fully simulated) • Import board layouts from Eagle (imported layouts are for wiring/layout reference and do not simulate) • Import custom 3D models to attach your projects to, and simulate their behavior on the workbench • Import images for reference or documentation and place them as physical photographs HOW IT WORKS Add parts to the 3D workbench and they land on the table with gravity. Drag parts around, then draw wires between ports to connect them. When a circuit is completed, it starts simulating immediately. Wires stay connected as you move parts, so you can build tidy panels and enclosures, or leave parts scattered like a real bench. iCircuit 3D was designed for fun and exploration, with plenty more to discover as you build. I hope you enjoy this new take on circuit software.

Verdict
The clearest difference is price: Circuitry at Free against iCircuit 3D's $12.99. Circuitry also leads on update cadence (every 4 months vs every 31 months) and review sentiment (51% vs 41%). On rating, ratings volume, ads and in-app purchases 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
Circuitry is free to download; iCircuit 3D costs $12.99 up front. Neither carries in-app purchases, so what you see is what you pay.
iCircuit 3D holds the better App Store score, 4.1 against 3.9. Both are backed by a comparable volume of ratings — 155 and 72 respectively. Written reviews complicate that: 51% of Circuitry's written reviews are positive against 41% of iCircuit 3D's, so the app with the better star average is not the one people write more warmly about.
Circuitry ships an update every 4 months, iCircuit 3D every 31 months. The most recent releases landed on September 25, 2026 and September 3, 2026 respectively.
