Logic vs Galton Board App
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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!
Galton Board App
Explore probability and mathematical concepts through an interactive simulation. This app uses your device's gyroscope to create a dynamic Galton Board, illustrating binomial and normal distributions. It also offers a stock market simulation to demonstrate market return probabilities.
- Interactive Galton Board simulation
- Binomial and normal distribution demonstration
- Stock market data simulation
- Detailed mathematical concept explanations
- Pause and slow-motion controls
- Historical market return bead simulation

Unlock the power of probabilities and explore the beauty of mathematics in motion with the Galton Board App. This innovative application transforms your mobile device into a dynamic, interactive probability demonstrator that brings centuries-old mathematical concepts to life. The app utilizes your iPhone's and iPad's gyroscope capabilities, creating an immersive experience where the beads appear as if they are rolling around inside your device. The Galton Board was invented by Sir Francis Galton in 1873 to illustrate the binomial distribution. Through our app, we've recreated this educational tool to demonstrate how, with a large number of beads and rows of hexagons, it approximates the normal distribution - a concept known as the Central Limit Theorem. Key Features: • An interactive Galton Board that displays the principles of probabilities and the binomial distribution. • Detailed explanations of related mathematical concepts, including probability theories, independent identically distributed (IID) random variables, regression to the mean, the law of large numbers, the random walk, the Gambler's Fallacy, and more. • A "Stock Market Data" version, simulating the probabilities of a range of historical monthly market returns, and demonstrating their correlation with the binomial distribution. • The 'Historical Monthly Return Beads' featured with the Stock Market Data, where beads fall through the board based on monthly historical returns for a choice of 20 index portfolios. • Pause or slow-motion options to study the bead movement and distribution patterns in detail. The Galton Board App is ideal for statistics, math, and stock market enthusiasts. It is not just an app, it's an immersive, hands-on approach to understanding probabilities, the binomial distribution, and the stock market behavior. Presented by Index Fund Advisors, this app is your go-to educational tool. Download now and embark on a fascinating journey into the world of probabilities and the "law of unreason" as referred to by Sir Francis Galton himself!

Verdict
The clearest difference is review sentiment: Galton Board App at 100% against Logic's 21%. Galton Board App also leads on rating (5.0 vs 3.6) and ads (none vs shown). Logic's advantage is in-app purchases (none vs 1). On price, update cadence, device support 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. Galton Board App sells 1 one-off in-app purchase. Logic asks for nothing beyond the download.
Galton Board App holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Galton Board App has 116 ratings behind it against 7, 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 100% of Galton Board App's.
Logic ships an update every 5 weeks, Galton Board App every 3 weeks. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
