*2011-05-30, version 3.4*

Simple and accurate.

### 4/5 — Works Well

*2010-09-13, version 0*

Contrary to what the pictures show the app is in English.
The default server was in Europe but switching to a NY server (where I am) doubled my speed.
Results are consistent with other working free apps.
