### 3/5 — Nice app but has a bug

*2020-08-19, version 1.0.12*

Some complex numbers don’t display properly. For instance, enter 41i and it will show up as 4i.

### 5/5 — 🇮🇹

*2020-04-15, version 1.0.12*

Vai Antonio orgoglio nazionaleeeee

### 5/5 — Mi farai prendere 10 al compito

*2020-04-15, version 1.0.12*

Fantastica!

### 5/5 — Amazing

*2019-02-09, version 1.0.7*

Complimenti allo sviluppare ottima grafica nessun rallentamento è colei molto azzeccati

### 5/5 — Awesome

*2018-04-21, version 1.0*

Works great. I would have like it if the buttons were raised a lot quicker and went back down slower. In its current state, buttons give the impression that they are slow and not being recognized. It work flawlessly though, just the impression is buttons are slow. 

Great app. Will be using it from now on.
