Apr 07, 2012 - Olaf Niggemann is proud to introduce Callmanager 1.0 for iOS devices. Everyone knows the problem, everyday correspondence happens mostly via mobile phone, and sometimes one or more important phone call can be forgotten. Now you don't have to worry about this any more. The Call Manager App is all you need to handle all of your daily correspondences. The app software can synchronize easily with your iPhone address book. Of course you may also add any contacts manually to the app.
