## What is LogicGate?

LogicDesign is the most powerful digital logic circuit simulator built for iPhone and iPad. Whether you're a student studying computer architecture, an engineer prototyping circuits, or a curious mind exploring digital logic — LogicDesign puts a full lab in your pocket.

DESIGN YOUR CIRCUITS
• Drag and drop logic gates: AND, NAND, OR, NOR, XOR, XNOR, NOT, Buffer
• Add Flip-Flops: JK, D & T for sequential circuit design
• Draw wires intuitively between any inputs and outputs
• Simulate in real time with live signal propagation

ANALYZE IN DEPTH
• Auto-generated Truth Tables for any circuit
• Waveform Viewer — watch signal timelines like an oscilloscope
• Boolean Equation view — instantly see the simplified logical expression

LEARN FROM EXAMPLES
• Built-in library with Half Adder, Full Adder, SR Latch, 2-bit Counter, and more

MANAGE YOUR PROJECTS
• Save, load, and organize unlimited circuits
• Export professional PDF circuit reports to share or print
• Fully offline — your data never leaves your device

PRO SUBSCRIPTION REQUIRED
Full access to all features requires a LogicDesign Pro subscription. Choose from a weekly, yearly, or lifetime plan. A free trial may be available.

### 1/5 — It immediately asks for a purchase.

*2026-06-07*

It immediately asks you to buy a subscription without even letting you try the functionality first. You’re basically buying a pig in a poke. There should at least be access to the basic features so users can understand whether it’s worth buying or not.
