About

Boolean Algebra

This app helps users understand and solve complex Boolean expressions. It allows for direct K-Map updates, truth table generation, and circuit diagram visualization. Users can interact with minimized circuits and learn about logic gates.

Highlights
  • Resolve complex Boolean expressions
  • Update K-Map and derive minimized solutions
  • Generate truth tables and corresponding circuits
  • View and interact with minimized circuit diagrams
  • Learn about logic gates (AND, OR, NOT, etc.)
  • Dark Mode support

After enormous success in desktop for over a decade, the original "Boolean Algebra" app is here on iOS. What it does, well almost everything. - Resolve complex Boolean expressions. - Directly update K-Map and derive minimized solutions (all possible minimal solutions, not just one). - Update Truth table and generate minimized K-Map values, corresponding circuit, and lot more. - View and interact with minimized circuit. You can also switch between all the minimal solutions available. - Tapping on the variable name in the circuit will toggle its value, zero or one, and update the circuit accordingly. - You also have an option to view Sum of Products, Product of Sums, Min terms and Max terms. - Interactive section(s) to learn more about all the gates (AND, OR, NOT, XOR, XNOR, NAND and NOR) - Option to change variable order in K-Map - Dark Mode What is next? - Quick search for minimized solution. - Easy to verify answers with explanation (why it is wrong) - Option to generate circuits using universal gates - Adding "do not care" option - Support for more than four variables - Zoom in/out in circuit

Verdict

The call

The clearest difference is rating: Kmap at 5.0 against Boolean Algebra's 4.0. Kmap also leads on review sentiment (100% vs 68%). Boolean Algebra's advantage is update cadence (every 4 months vs every 128 months) and ratings volume (24 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.
