### 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.

### 1/5 — Do Not Buy !

*2021-01-30, version 4.4.1*

Waste of money!

### 5/5 — Great App

*2020-09-12, version 4.3*

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

### 2/5 — Quero meu dinheiro de volta

*2019-09-21, version 2.5.2*

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

### 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.

### 4/5 — Does the job well

*2018-10-31, version 2.3.3*

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

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

*2018-06-08, version 2.2.1*

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!

### 5/5 — Excellent

*2017-07-23, version 1.4.2*

Very good, saved my on my classes.

### 5/5 — Good map

*2016-08-26, version 1.4.1*

thank you karn !!
