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.

The CircuitDesign is a feature rich app designed by an engineer. This app allows the creative smart people like you to design, draw, analyse, simplify and solve electrical circuits. You can design, draw, solve and simplify resistor-network, solve capacitor-network, solve inductor-circuit. You can design, draw, solve and simplify parallell circuit diagrams, series circuit diagrams, delta/wye circuit diagrams and any combinations of these. You can convert delta to wye and wye - delta network You can convert current source to voltage source or voltage source to current source You can design your own resistor (3,4,5 or 6 band resistor) or find the value for existing resistor You can even share your creativity with other people. Save the diagram locally. Do you have a complex network involving any combinations of parallell network, series network, delta/wye network? Fantastic. You can simplify this network and see how its done step by step so you can learn how to simplify networks. You can go back all the way to original network to see how the simplification was done. Simply stated, view simplification steps graphically. Keeps the historical diagram so that you can go back and verify each step. You can also share the simplification steps 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 of drawing diagrams and simplifying/solving it will not be lost. Are you a high school student learning electricity? This is the app for you. Are you a university student learning electrical engineering? This is the app for you. There is also a page to help you study. This study tab teaches you some very important laws of electricity and important formula. Like Ohm, law, Kirchhoff's volgate law, Kirchhoff's current law, There is also a page to help you learn now to use this app. 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 call

The clearest difference is review sentiment: Kmap Solver at 67% against Circuit's 0%. Kmap Solver also leads on rating (3.4 vs 1.0) and ads (none vs shown). Circuit's advantage is price (Free vs $3.99) and update cadence (every 5 weeks vs every 9 months). On in-app purchases and device support there is nothing between them.
