The last time we talked about the Viber, many users complained about the same thing: the app was still old look from iOS 6. Now, almost a year after iOS 7 was introduced to the world, the developers of the free calls tool have finally adapted their work to the current look of the system.
In addition, Viber also gained the function of blocking numbers and contacts (oddly enough, this did not yet exist in the application) and the possibility to send multiple photos at the same time and longer videos.
Viber is free and requires a phone number to work, which makes it useful only on the iPhone. It does not have an iPad version.
