LogicSimulator is a Free app that helps you learn Logic designing , computer science engineering and electrical engineering

This app let you desing circuits using Logic gates , where you just need to connect diffrent components with each other and start simulation

it has a simple user interface which let you interact with the components easily which will eventually increase your efficiency

This app includes many Logic components like

OR , AND , NAND , NOR , XOR and many thing

Input components
Push Button, Toggle Button , Frequency generator

Output components
Bulb , RGB light , 7-segment Display , Dot pixel display

The simulator has 3 modes

Touch mode - To interact with input devices and avoid unwanted changes
Edit mode - To edit design of the circuit , it avoids Input components interactions , can select components , pins and Labels
Disconnect Mode - To disconnect connections between components

here you can create a multiple Pin gates
it has n-pin AND , OR,XOR and etc

The components are
