Ill be honest—I dont really have a need for grouping contacts, but it seems I did need to do so at some point, thus I had purchased this app. I havent fully explored it, but it seems to work well and do what it advertises. Ostrich Eggs is also updating the app regularly, it seems, so no complaints there, either. In all, a good grouping app.
