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 call

The clearest difference is in-app purchases: Circuitry at none against Electronics Toolkit!'s 1. Circuitry also leads on ads (none vs shown) and review sentiment (51% vs 38%). Electronics Toolkit!'s advantage is rating (4.3 vs 3.9) and update cadence (every 2 months vs every 4 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Electronics Toolkit! sells 1 one-off in-app purchase. Circuitry asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Electronics Toolkit! holds the better App Store score, 4.3 against 3.9. Both are backed by a comparable volume of ratings — 556 and 155 respectively. Written reviews complicate that: 38% of Electronics Toolkit!'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.

UpkeepUpdate frequency

Electronics Toolkit! ships an update every 2 months, Circuitry every 4 months. The most recent releases landed on October 12, 2026 and October 7, 2026 respectively.
