Its a very good application which provides the options that have been missing in iOS contact application. However, it needs a lot of improvements before it can be called an excellent and reliable application. Some of those wishes are listed here:
1. Sometimes it picks up a wrong format from the phone contacts and then doesnt dial with double tap unless you add the contact manually.
2. The dial pad should be larger and there should be an option to look at history or go ahead with new numbers. History should not come up on dial screen.
3. In the history, multiple calls to one contact should not appear in multiple lines, they can be shown as number of calls made to the contact with optional detail.
5. To make it more useful, it could be integrated with all social media listed. I mean it should be able to send emails or call the contacts on social media.
