Logic Circuit Simulator Pro

What the simulator is for

Logic Circuit Simulator Pro is a digital circuit simulator for Android. You place logic elements on a board, wire them together, and watch how the circuit behaves. The developer names Multisim, SPICE, LTspice, Proteus and Altium as tools people in this field know, and positions this app as a lighter, digital-only way to practise the same kind of design.

The listing pitches it at people who want to learn how electronics works, including those studying electrical engineering. It is a fit for a student working through basic logic design, or anyone who wants to test a gate arrangement without a breadboard.

Building digital logic circuits

The main job of the app is designing combinational logic circuits, where outputs depend only on current inputs. The developer describes the interface as intuitive and says it offers many options for exploring a design.

The element library covers logic gates, programmable arrays, latches, flip-flops, signal generators and device sensors. Latches and flip-flops let you add memory-style behaviour to a circuit, and generators supply the input signals to test it with. The developer lists these together as the parts you combine to build and try out a design.

Saving, sharing and nesting circuits

Circuits can be imported, exported and shared, so a design built on one device can be sent to someone else or moved between your own devices. The listing does not describe the file formats used.

The developer also lists embedding, which lets one circuit be placed inside another. A subcircuit built once can be reused as a single block in a larger design, which suits building up a complex circuit from smaller parts.

Learning from element references and tutorials

Each element in the library comes with information about what it is and how it works, so the app doubles as a reference while you build. The developer also lists a set of tutorials and usage tips meant for when a design stalls.

Together these turn the simulator into a learning tool as well as a sandbox. You can look up a flip-flop's behaviour, place one in a circuit, and check the result in the same session.

Themes, dark mode and tablet layout

The app offers customisable themes and a dark mode, which the developer says is intended to reduce eye strain. The listing also states that the layout is designed to make use of a tablet screen, which gives a large board room to lay out a bigger circuit.
