### 1/5 — Do Not Buy !

*2021-01-30*

Waste of money!

**Developer response:** Hello, we would be glad to hear what you found missing in the app so that we can improve it. Thank you!

### 1/5 — Waste of money

*2019-09-21*

Found free Karnaugh solvers on the internet. This was a huge disappointment.

**Developer response:** All app features are listed in the app description. We believe that this app provides distinct capabilities such as the algebraic minimiser, XOR optimization, customization of the Karnaugh maps and ease of use.

### 1/5 — Letzter Rotz

*2014-01-29, version 1.1.1*

Die App ist der letzte Rotz !
In den Bildern ist die Vollversion gezeigt, mit der Gratisversion kann man nichts machen !
War keine 60 Sekunden installiert. Spart euch den Traffik !

### 2/5 — Limited functionality

*2021-02-28*

Over priced for limited functionality.

**Developer response:** Hello!
We are sorry for your experience. Kindly let us know which price you would have found appropriate.

### 2/5 — Quero meu dinheiro de volta

*2019-09-21*

Comprei achando que fazia uma coisa, mas não faz.. quero o estorno do meu pgto.

**Developer response:** Hello, contact us at info@kappsmart.com so that we may assist you in getting your refund.

### 4/5 — Does the job well

*2018-10-31*

Well worth the full version. The only thing I don't like is that the solver doesn't recognize XNOR.

**Developer response:** Hello, in the latest version we have added support for the XNOR operator!

### 4/5 — Ganz gut

*2016-07-22, version 1.4.1*

Das die freie Version nicht alles kann dürfte klar sein, aber 4 Variablen reichen für die meisten Fälle aus.
Ich wünsche mir aber die Möglichkeit, die Variablen frei zu benennen und Spalten in gewissen maße selbst anzuordnen.
Aber die App arbeitet richtig und flott, daher 4*.

### 5/5 — Great App

*2020-09-12*

Great app and customer service!! Customer service helped me understand how to use the formula. Thanks.

### 5/5 — Exelente App

*2020-07-19, version 4.1.2*

Todas las funciones muy prácticas

### 5/5 — Excellent tool for an uber efficient process!

*2018-06-08*

Have used this almost daily since I imagined such a product existed, and then went looking for it.

And with each update, it continues to get better and better! I teach PLTW Digital Electronics for a magnet engineering high school, and all of my students learn to do this by hand. This tool lets me quickly check their maps, build my own clever maps more quickly, and just generally makes our lives better!

Thank you to the developers for continuing to improve this excellent product!

**Developer response:** Thank your for providing your feedback over the years! We enjoyed hearing how you discovered the app, your use case and how the app meets your expectations. This app is also special to us and we will continue to make it the tool of choice for Karnaugh map users!
