### 5/5 — Amazing app

*2014-05-18, version 3.51*

Awesome

### 3/5 — Step back

*2014-04-25, version 3.01*

Version 2 was a great improvement on 1, but 3 is "rocks in the head"! I really, really, really hate the new look. Harder to read, more bland, less contrast, and worst of all prone to serious mistakes by including rates no longer used. 
The core functionality is good but too easy to make errors on this non-tactile, non-visual keyboard. Insane idea to include historical gst rates. 
Have a look for something easier to read.

### 5/5 — Version 2...

### 4/5 — Clean and Simple

*2011-07-21, version 1.02*

Good clean simple well done app.  It would be even better with a choice between querty keyboard or calculator numeral layout, after all it is often used while accounts are being done.

Very easy to check gst.

### 5/5 — Does what it should

*2011-01-08, version 1.02*

A basic, but very handy app. Simple and easy to use. Since I have updated the app the backspace key now works.

### 4/5 — Handy

*2011-01-05, version 1.0*

Good app. Would be great if it used the number keypad instead of the full keyboard. Also I can't use backspace for some reason??

Otherwise very handy.
