Limited
The app is very limited with 5 international, NY or San Fransico server locations. As stated in another review, if you live in or around one of the supplied cities it might be of use, otherwise, it will report slow speeds mostly due to distances. The app owners would do themselves a lot of good by adding more server locations. I dont intend to spend the time to enter into "terminal" and screw around with scripting to creat something that should come with this apps.
For "$1", it is wasted time and money.
