I just downloaded the Lite version to evaluate the app. It seems simple yet powerful enough to do most things. In my mind, what would make this app perfect are the following:
1. Ability to import from Contacts groups. These groups are synced to iCloud from the Mac and it seems that this app is already aware of them, because you can add a contact to them. But sadly, you cannot import contacts directly from a group. This would help tremendously in keeping work contacts separate from home contacts.
2. The interface could use some customization abilities. I would love to change the font size, for example.
Other than that, this app seems to have what I need.
