Contacts Grouping 4+

Previous reviewers may not have understood how this program works. I have ios6 and both an iPhone 4s and iPad2. I have tested this program out and found it does what it says.
You can create or delete groups. You can change contacts from one group to another or include them in multiple groups. You can find who is in no group and include them in a group or groups. It all syncs as you would expect between the iOS devices and my iMac.
The "secret" is the use of the "edit" button. When in the groups window the edit button brings up a list of choices such as new group, sort groups, remove groups. When you are inside a particular group you can select edit (don't select a contact unless you want to see the details) and you will see a listing of all your contacts. Those in the selected group have a tick next to their name. You simply select/deselect names so that only those with ticks are included in the chosen group.
Any contact that doesn't have a tick in any group automatically goes into the "no group" category. This is slightly different in that when you select edit in this group you are given the choice of entering the selected contact into an existing group.
It may not seem intuitive at first but once you get the hang of it you find it is very useful and easy to manage.
My only gripe (apart from the unusual interface) is that you can not use the program in landscape mode. It remains in portrait. This would be a helpful correction.

This is a terrible app. It's a waste of money. Please don't buy it. It doesn't work. I feel like I've been ripped off. It doesn't sink your old contacts from the apple contacts app into the new groups you want. I do not recommend this app. When you go to "NoGroup" option to try to add contacts from your previous contact list which you had already written in the apple contacts app, it doesn't add the contact that you have checked to the group you want. You will have to re-write the contact and all their details all over again in the new group. So sad :(,,,, I want my money back.

On the surface this App suggests it is one of the better Contact grouping Apps. I have been disappointed with it in three ways.
The Sort facility is Manual. This is a really big negative.
It claims to be an iPad App, but does not recognise landscape use.
There was no help, or mechanism to contact the Developer to help them improve the App.
Sadly a wasted purchase.
