## What is iCircuit 3D?

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.

### 5/5 — Search function

*2025-12-01*

Great app, but is it possible for you to add a search function for adding stuff on vertical mode on an iphone? It’s annoying to have to scroll so far sometimes. Thank you

### 1/5 — Honest.

*2024-06-30*

Save your money, as it doesn’t work.

### 5/5 — .

*2024-06-29, version 1.1*

How the heck are parts assembled together?
It’s very difficult to attach them together.

Wheels are very buggy when attaching something to them, they fly upwards when attached to some things, like blocks and motors, please fix that.

### 5/5 — Great just one slight problem

*2024-06-18*

It’s hard to control the camera angle

### 5/5 — Be a bright spark!

*2024-05-03*

For someone like me learning electronics, this app is incredible! Bravo! Bunch of bright sparks who created this!

### 1/5 — This app is a lie!

*2023-11-22, version 1.1*

Bad, so bad

### 1/5 — Very Disapointed

*2023-10-27*

I bought this app for about $13 but when I downloaded it to my Mac Mini, which according to the information on the App Store is a viable option, it was imposible to use. I can create a new project, and add some things like a power supply, and bread board and Oscilicope. But that is where it ends, you cannot manipulate the objects very well and you cannot add any part's to the bread board using the mouse. It is using the aspects of the iOS not the Mac OS and thus you cannot manipulate basically any of the parts. The manual is awful with no mention on anything on the Mac side. So you are forced to pay for a waste of time with no help. Very very disapointed.

### 2/5 — Crashes often and not full-featured enough for me

*2023-06-22*

Crashed twice in 30 minutes.

### 5/5 — Awesome App!

*2023-06-03*

Suggest using the original iCircuit to become familiar with things, then apply to this app!
Great apps both of them are!

### 3/5 — Great potential overshadowed by bad UI

*2023-03-21*

I have spent way too much effort just to move my components and keep them there. The slightest touch nearby and they flip, turn or move. It’s very frustrating to have to fight with this interface so much. 

It could be great except this makes me want to look to other products.
