Today we have updated Vopium for Android. The update includes a new and improved user interface. Among other things we have added a contact list where you can see the rate before calling your friends and a new test number functionality that allows you to test the voice quality.
We have made a number of under the hood fixes to improve your calling experience and added support for Android Jelly Bean. If you have any feedback, please do not hesitate to shoot an email to firstname.lastname@example.org.
