## Description

The most enjoyable and realistic Digital logic gates circuits simulator.

DigicalSim (formerly: iLogicDesigner) is a full featured app which assists students in logic design, digital engineering, computer science and mathematics.
The app based on basic digital building blocks, logic gates. No knowledge of logic gates or digital circuits is required.
It offers the basic building blocks, wiring tools and a flexible plane to create live real-time digital circuits, ideal for anyone who wants to learn the basic principles of how computers work - especially students of digital engineering, learn how to create simple logic gates, latches, flip-flops, adders, shift registers and counters. it can help them perform complete lab experiments.

## Review summary

Reviewers consistently note that Digital Circuit Simulator Lite provides realistic circuit simulation and learning value, even in the free version. The main drawbacks are the heavy paywall/limited lite features, plus performance and usability issues like lag, battery drain, and awkward wiring controls. Some praise the developer’s responsiveness to feedback. Overall, it’s a solid educational tool when accessible, but paywall and UX/performance issues limit everyday use.

### Pros

- Realistic logic circuit simulation (gates, flip-flops, and a clock timeline).
- Free version provides meaningful, usable functionality before purchasing.
- Useful learning tool to visualize how circuits behave.
- Developer responsiveness and updates addressing user feedback.

### Cons

- Lite version heavily restricts features with item limits and nudges users to upgrade.
- Significant lag and battery drain; poor graphics and slow performance.
- Unintuitive controls with difficult wire connections and awkward gate movement.
