Why is Buzz Contacts no longer in the App Store?
Buzz Contacts has always been limited on iOS by not having access to call history, voicemails, and similar items. With the arrival of iOS 7, we had hoped to see progress on these fronts. Since that is not the case, we unfortunately could not justify further investment into this app and decided to remove it from the App Store. Effective September 18, 2013, we will no longer be providing support for Buzz Contacts.
For those looking for a great alternative to Buzz, we recommend Contact Center by Contrast. Any questions about Contact Center should be directed to the Contrast team -
