### 1/5 — One star is too many stars

*2015-09-26*

Terrible, no keyboard therefore you cannot use letters or mathematical signs. Do not waste your money, I would like a refund!

### 1/5 — Wie bitte?

*2015-06-30*

Totaler Müll, funktioniert nicht, kostet aber!
Nein Danke, Finger davon.
Ein Stern ist noch zuviel.

### 1/5 — Cuidado

*2015-02-28, version 1.0.1*

Falla después de la primera operación. Hay que reiniciar para que vuelva a funcionar. Una estafa. Si pagas, por lo menos que funcione.

### 4/5 — Sempre meglio

*2014-11-25, version 1.0.1*

Mancherebbe giusto la fattorizzazione anche dei risultati, prima del valore.
Grazie

### 5/5 — great

*2014-02-25*

it works extremely well, and the calculations are easily read and accurate.

### 5/5 — Quick Gcf Lcf

*2013-10-17*

Great app for confirmation of gcf and lcf and 3 number input is a big advantage over TI calculators which only handle 2 numbers at a time.

### 5/5 — Great Math App!!
