Truth Table Builder vs Logic
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Truth Table Builder
Easily construct truth tables from Boolean formulas. This app supports up to 8 variables and can display sub-expressions, ensuring the original truth function is preserved. It offers a custom keyboard for input, saves and shares tables, and allows operator customization.
- Build truth tables up to 8 variables
- Shows sub-expressions
- Preserves original truth function
- Generates random expressions
- Supports custom operators and constants
- Saves and shares truth tables

Truth Table Builder is an easy, quick and reliable app that builds truth tables from Boolean/propositional formulas that you enter. Features: - Build truth table of up to 8 variables - Shows sub-expressions of the main expression - Splits expression based on operator precedence rule so that original truth function is preserved - Generates random expressions - Supports all variable letters and logical operators - Custom keyboard for easy input of expressions - History of all entered expressions - Save and share truth tables - Customize operators and truth constants
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 price: Logic at Free against Truth Table Builder's $1.99. Logic also leads on update cadence (every 5 weeks vs every 6 months). Truth Table Builder's advantage is rating (4.7 vs 3.3) and review sentiment (60% vs 21%). On in-app purchases and device support there is nothing between them.
