Circuitry is a hands-on logic game that makes Boolean algebra, logic gates, and digital circuits easier to understand. Build circuits by connecting AND, OR, XOR, NOT, and other gates, then experiment with different inputs to see how signals travel through your design. Work through 22 progressively challenging problems to unlock new components. Then use Playground Mode to create and test circuits of your own. Features: - 22 logic-circuit problems - Interactive circuit building and simulation - 36 different circuit components - Playground Mode for creating your own circuits
Logic
Design, simulate, and simplify logic gate networks. Generate truth tables, minimized boolean expressions, and waveforms. This app is ideal for students and engineers to explore digital logic.
- Design logic gate networks
- Simulate network behavior
- Generate truth tables
- Minimize boolean expressions
- Create input-output waveforms
- Study boolean algebra theorems

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!

Verdict
The clearest difference is review sentiment: Circuitry at 96% against Logic's 21%. Circuitry also leads on rating (4.8 vs 3.3) and ads (none vs shown). Logic's advantage is update cadence (every 5 weeks vs every 46 months) and monetization model (ad-supported vs paid). On price, in-app purchases and iOS requirement 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. Neither carries in-app purchases, so what you see is what you pay.
Circuitry holds the better App Store score, 4.8 against 3.3. That said, the two scores are not equally well evidenced: Circuitry has 291 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 96% of Circuitry's written reviews are positive against 21% of Logic's.
Circuitry ships an update every 46 months, Logic every 5 weeks. The most recent releases landed on September 18, 2026 and June 5, 2026 respectively.
