## What is Circuitry?

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

## Key features

- 3D circuit building
- GPU-accelerated analysis
- Intuitive 3D interface
- Document-based circuit files
- Component placement and connection
- Resistor, voltage source, light bulb components

### 4/5 — Cool but some stuff is missing

*2025-09-28*

The game idea is really cool, but it missing a lot of stuff and maybe could add names for the components so we know what we are placing down.

### 1/5 — Huh?

*2025-02-26*

I’m sorry, maybe I missed something, but did you really make an app with literally four things you can do and advertise it as a circuitry app? Categorized as educational? I really hope I missed something. If I didn’t, you really should consider taking this app down, because the only thing this app has been able to do for as long as it’s been around-if I’m correct-is create a light source that requires a battery AND some other thing to work. Not a battery and a light bulb, no, a battery, some other thing, and a light bulb. That is not how electricity works. Please tell me I’m wrong, and that I just don’t know how to find the speakers, the microphones, the capacitors, the resistors, the switches, the transistors, the LEDs, the displays, the transformers, and all the other stuff that literally any other platform has. Please.

### 3/5 — Components

*2025-02-06*

It’s nice and 3d, but I would love it if you added more components like a diode or transistor. Adding labels would be nice to let us know which parts are which.Other than that, It’s great!

### 4/5 — Casi perfecto

*2024-09-12*

Sería perfecto si también tuviera intensidad y voltaje de los cables pero de ahí en mas esta muy bien

### 3/5 — Cute, but not useful

*2024-07-23*

This is a really cute/fun user interface, but with only three types of components, I can’t simulate any circuits that are relevant to the type of work I do. And I can’t see it being particularly useful to the majority of others who might download it.

### 5/5 — Fun way to learn electronics!

*2024-06-21*

As the version gets higher I hope that more components will be available like capacitors,
Inductors etc.

### 1/5 — Can’t even play/

*2023-10-13*

I opened it, doesn’t work, restarts it, doe sent work, why?

### 2/5 — Will not open ?

*2023-09-06*

Very strange.  I tried downloading App twice and each time only a folder appears in my iPhone ‘files’.  Going to home screen to find and click app icon takes you back to file folder, but nothing happens in either case. This is why I’m giving it two stars for now. Maybe someone can tell me what’s going on

### 4/5 — Components

*2023-08-04*

It’s nice and 3d, but I would love it if you added more components like a diode or transistor.Adding labels would be nice to let us know which parts are which.Other than that, It’s great!

### 5/5 — This game is awesome

*2022-12-25*

This game is very fun and simple. Also this game is very exciting for someone who wants to learn electrical engineer like myself.
