The LogicGateDesign is a feature rich app designed by an engineer. This app allows the creative smart people like you to design, draw, analyse and simplify logic gate networks. You can draw logic gate networks and share it with others. You can generate truth table and find simplified/minimized boolean expression that represents the network. You can optimize and reverse engineer a boolean expression to draw a ladder logic diagram. It performs both forward engineering (boolean expression to logic circuit) and reverse engineering (logic circuit to boolean expression). There can be multiple groups of network and each group can have multiple outputs. Truth table is generated for all the outputs. You can simplify a boolean expression, and find the truth table and share it. Show truth table along with different types of boolean expression (simplified, Sum-of-products, Product-of-sums) The simplified expressions also gives you the number of gates required. You also get the alternate expressions for the same output with the gates required for that. You can generate a truth table, simplified boolean expression using input-output waveforms. You can generate a output waveforms, simplified boolean expression using truth table and input waveforms. You can generate a grey codes and grey code encoder wheel and share it. Do you have a truth table for your network and want to find the simplified/minimized boolean expression? This app has you covered. You can simulate your network by changing one input at a time or toggeling all inputs at once. This app generates beautiful diagrams (logic gate diagram or waveform diagram) that you can share with others or save it locally. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There is also a page to help you study. This study tab teaches you some very important boolean algebra theorems. This is a perfect app for a creative smart individual like you. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
LogicGates
Explore the fundamental principles of computer operation by understanding how simple switching circuits can perform basic arithmetic functions like addition. This app demonstrates logic gate concepts, potentially inspiring users to build their own computing components.
- Explains basic computer switching circuits
- Demonstrates addition function using logic gates
- Introduces fundamental logic gate principles
- Potential for hands-on computing component creation

The basic principle of a computer is a combination of some switching circuits. The light switch that we normally use is a switching circuit, and the computing chip uses a very large number (currently hundreds of millions) of circuits to achieve a fast computing function. This APP is to introduce how to use some switch circuits to achieve an addition function. This is also the basic principle of logic gate, after understanding the basic principle, maybe you can make CPU by hand.

Verdict
The clearest difference is in-app purchases: Logic at none against LogicGates's 1. Logic also leads on rating (3.3 vs 3.0) and review sentiment (21% vs 0%). LogicGates's advantage is ads (none vs shown) and update cadence (daily vs every 5 weeks). On price and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. LogicGates sells 1 one-off in-app purchase. Logic asks for nothing beyond the download.
Logic holds the better App Store score, 3.3 against 3.0. That said, the two scores are not equally well evidenced: Logic has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 21% of Logic's written reviews are positive against 0% of LogicGates's.
Logic ships an update every 5 weeks, LogicGates daily. The most recent releases landed on October 12, 2026 and September 19, 2026 respectively.
