## What is LogicalArt?

LogicalArt is a digital logic simulator where you build a computer from nothing but logic gates. Wire NOT, AND, OR and XOR gates, switch on the power, and watch every signal travel through your circuit.

No breadboards, no soldering, no tangled jumper wires. Just the ideas behind how a CPU really works, made visible on your iPhone, iPad and Mac.

LEARN BY BUILDING: GUIDED CHALLENGES
Work up a ladder of hands-on puzzles: Half Adder, Full Adder, Multiplexer, Decoder and a 1-Bit ALU. Label your inputs and outputs, tap Verify, and LogicalArt plays the whole truth table on your live circuit, row by row, so you see exactly where it works and where it doesn't.

FROM GATES TO A CPU
• Four basic gates: NOT, AND, OR, XOR. Everything else is built from them.
• Package any circuit into a reusable chip, then build bigger designs out of your own chips.
• Create EEPROM chips straight from a truth table.
• Build latches, flip-flops, registers, counters, adders and an ALU, step by step toward your own 8-bit computer.

SEE WHAT YOUR CIRCUIT IS DOING
• Deterministic simulation with real gate delay, so clocks, latches and feedback loops behave the way they should.
• Clock inputs, number displays and a live view of every wire's state.
• Waveform view to follow signals over time.

MADE FOR TOUCH, TRACKPAD AND MOUSE
• Drag to place gates and draw wires; pinch, scroll and zoom around large boards.
• Undo, labels and a clean layout that stays readable as your designs grow.
• Native on iPhone, iPad and Mac.

SHARE AND DISCOVER
Browse boards from other builders and share your own.

WHO IT'S FOR
Computer science and electrical engineering students, teachers explaining digital logic, programmers curious about what happens below assembly and Verilog, and anyone who has ever wondered how a computer actually works.

FULL ACCESS
Start for free. A one-time Full Access purchase unlocks every feature: unlimited boards, chip packaging, EEPROM chips and sharing. No subscription required.

### 5/5 — Got a bright future!

*2025-03-10*

This is honestly a fantastic concept with an almost flawless implementation. UI elements and color choices are awesome!. Gate inputs and outputs are a little tricky to work with because of the small screen and the inability to move wire freely and extend more than one wire out of one gate or in one gate, input naming can also use some improvements. But given the challenge of making a logic simulator on a small phone screen (I know there are iPads but I’m on iPhone), the app has done a great job so far. I believe this has the potential to become one of the best logic simulation tools available on iPhone.

**Developer response:** Thanks for the feedback! I will improve it in the next update.

### 1/5 — Impossible to understand

*2023-02-10*

Theres no way to actually know how to use this app. You can tap to switch things on and off but there’s absolutely no indication of what that does. The UI is too bare to actually do it’s job of informing you what things do.

**Developer response:** Here is a quick start guide: https://www.crazylazy.xyz/apps/logicart/quickstart
You can also found it on the Wellcome screen when you open the app or the sidebar bottom left.

## Version history (last 5 releases)

### 1.30 — 2026-11-06

• Gates land exactly where you tap: placement now snaps to the nearest grid point instead of half a cell off.
• With a gate picked in the toolbar, dragging on the board places just that gate. No extra radial picker, no duplicate gate.
• On iPad, Challenges now sit in the top toolbar.
• Refreshed toolbar with the new glass look on iOS 26.
• Redesigned Full Access screen, with clearer messages when you restore a purchase.

Thanks for building with LogicalArt! If you enjoy it, a rating on the App Store really helps.

### 1.22 — 2026-08-19

The arrow at the edge of the board now clearly opens and closes the input drawer, so adding inputs is easier to find. Floating controls also stay steady while you drag on the board instead of reacting under your finger.

### 1.21 — 2026-07-30

New in this version:
- Step-by-step guided challenges: Brand new interactive challenge levels to guide you through digital logic step-by-step! Learn to build CPU components from zero.
- Enhanced circuit simulation & performance improvements.

### 1.20.1 — 2026-07-02

- Add more language support

### 1.20 — 2026-06-22

- Update supporting framework
