Kmap Solver vs Logic Kit
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Kmap Solver
This app solves Karnaugh Maps (Kmaps) for up to five variables, providing all possible solutions and displaying them on the map. It also generates four optimized output logic circuit versions, including traditional, common inverters, and NAND/NOR only circuits.
- Solves Kmaps for 2, 3, 4, or 5 variables
- Displays all possible Kmap solutions
- Shows four optimized logic circuit versions
- Traditional circuit output
- Common inverters circuit output
- NAND/NOR only circuit output

This application solves Karnaugh Map, also called Kmap, for 2, 3, 4 or 5 variables. It is the only application I know that will provide (and show on Kmap) ALL possible kmap solutions. It will also shows four different versions of an optimized output logic circuit: a tradicional version, a circuit with common inverters and NAND/NOR only circuit.
Logic Kit
This app simplifies boolean algebra expressions and converts numbers between bases with detailed step-by-step solutions. It offers tools for Karnaugh Maps, truth tables, arithmetic, and complements, all accessible offline.
- Boolean algebra simplification
- Karnaugh Map solver
- Truth table generator
- Number base conversion
- Arithmetic in different bases
- Step-by-step solutions

The "Logic Kit" app helps you to simplify boolean algebra expressions by using boolean algebra laws, solve Karnaugh Map, Truth Table, Sum of Product (SoP), Product of Sum (PoS), convert numbers from any base to any base, do arithmetic between these numbers, find complements, and more. All this is provided with a detailed step-by-step to learn while solving. Boolean Algebra Features • Simplify boolean algebra expression using boolean algebra laws and show the detailed solution step-by-step. • Simplify the boolean algebra expression using Karnaugh Map and show the detailed solution step-by-step. • Solve Karnaugh Map by inserting values (SoP, PoS) directly in the map with the ability to use "Don't Care". • Find the truth table from the boolean algebra expression and show the detailed solution step-by-step, or easily insert values (SoP, PoS) directly in the truth table and get the boolean algebra expression consisting of Minterms or Maxterms. • Find SoP and PoS from the boolean algebra expression and show the detailed solution step-by-step. • Deal with the Sum of Product (SoP) and the Product of Sum (PoS), and get the boolean algebra expression consisting of Minterms or Maxterms. • Easily show a circuit diagram for any simplified boolean expression using AND-OR gates, NAND gates only, or NOR gates only. • In the boolean algebra expressions you can use all the English letters (26 variables) and 11 different logic gates (AND, OR, NOT, NAND, NOR, XOR, XNOR, IMPLY, NOT-IMPLY, CONVERSE, NOT-CONVERSE). • Truth table and Karnaugh Map can solve up to 10 variables. • Special design keyboard for the boolean algebra to write expression variables and gates easily. Number Systems Features • Convert numbers (with decimal points) from any base to any base (binary, octal, decimal, hexadecimal, etc.) up to base 36 and show detailed step-by-step. • Find r's and (r-1)'s Complement for any base up to base 36 and show detailed step-by-step. • Do arithmetic (Plus, Minus, Multiplication, and divide) between numbers in different bases and get the solution with detailed step-by-step. • Special design keyboard for the number systems that interact with the selected bases to write easily with no mistakes. More Features • The Logic Kit app works with no need for an internet connection, and there are no ads. • There will be many added features in the upcoming updates.

Verdict
The clearest difference is rating: Logic Kit at 4.9 against Kmap Solver's 3.4. Logic Kit also leads on review sentiment (100% vs 67%) and update cadence (every 9 days vs every 9 months). Kmap Solver's advantage is price ($3.99 vs $9.99) and iOS requirement (13.2 vs 17.0). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
