This app deletes many off your contacts

I have had this app for a while now, probably close to a year. The merge function seems nice but it deletes many of your contacts. Especially those that you use a lot. I.e my wifes contact info was deleted on several occasions. Not only that, because of iCloud synchronization I have had the full contact list deleted on one occasion. I have spent at least 20+ hours correcting the havoc this app creates. Do not buy it. Just do manual delete or merge or try another app. I am deleting this app right away.
