Delete Contacts Pro.

This app took it upon itself to eliminate VAST stores of vitally important information stored on contact cards that I will never recover, because for some unfathomable reason, when it merges contacts, it deletes the notes. It’s truly disastrous. I’d sue them if I could.

Mad props to Jaidev for vastly improving on iOS’s native batch contacts delete method (two finger swipe gesture), which is not practical when needing to delete truly massive numbers of contacts.
