About

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.

Highlights
  • 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.

About

Fx Minimizer

This app simplifies complex logic expressions using the Quine-McCluskey method. It supports minimization via minterms or truth tables, including don't care terms, for up to four inputs and two outputs. Results can be exported to a text file.

Highlights
  • Quine-McCluskey method
  • Minterm minimization
  • Truth table minimization
  • Support for don't care terms
  • Export results to text file
  • Multi-language support

Verdict

The call

The clearest difference is price: Fx Minimizer at Free against Kmap Solver's $3.99. Fx Minimizer also leads on iOS requirement (9.0 vs 13.2). Kmap Solver's advantage is rating (3.4 vs 1.0) and in-app purchases (none vs 1). On ads and device support there is nothing between them.
