Does what it says

Very clunky User Interface.
You need to go to “preferences” to perform actions that usually would be on the home screen.
Once you go to the support site to figure out why the UI is so counter-intuitive you will find that it does work.
Virtually all of the one stars are from folks who couldn’t figure out the interface.
It seems that he developer could make everyone love it if he added about 7 words to home screen, but instead he chooses to admonish people for not figuring out how to use it.
Tip:If the home screen had a choice 1) convert all contacts and 2) convert selected contacts and groups, then most complaints would go away.

But on the other hand, it is only 99 cents and it does work.
