Falls short of expectations

So, Im sending out Christmas cards and looking for a simple app to assist with labels. A quick Google search. Bam! Your the top hit, kudos!! Take a look, read a few reviews, its only .99, I do it.
Its pretty nice, simple, easy to use.
Okay, you know the "but" was coming, here it is.
This app is created for Apple products, yet its not Apple friendly.
Apple lets me sort contacts into groups, I have family, friends, co-workers, doctors, clients, kids friends.
In you app when I select the + button to add contacts to a card list it populates all contacts. How disappointing and now a waste of money. Having over 700 contacts and growing I need the ability to add a group or at the very least the ability to separate by group.
Sincerely Disappointed
