This is the simplest, quickest & most intuitive app I've seen for unit conversions. In addition to all the basics it has currencies, time zones and number base conversion for us engineers.

A sincere Atta boy to the developer.

### 2/5 — Useful now useless

*2013-01-25, version 2.0.1*

(Original 4 ⭐ rating) Good app, easy to use, clean interface ... Latest update rendered currency conversion useless. All currency converted says N/A. I do not have a back up of this app so I cannot revert to previous version. Please fix and I'll be happy to revert my comment back to original. I sometimes use other converter tools but I use currency everyday for business.
