Good App
Bought this app and tried to use it to create contact groups on my iPad2. Contacts came from gmail. Add and Sort groups work but cannot add individual contacts to groups. Some obscure message pops up about local sync.
Did some more research and found a way to sync contacts for gmail via iTunes. That fixed the problem so now I can easily add and delete contacts to groups. This app works great, once the contact sync is set up properly.
