## What is ContactClean?

Is your address book a messy collection of contacts imported from old phones and computers? Use ContactClean to eliminate duplicates and find missing data to clean your address book! Combine several partial contacts for the same person into a single complete one.  

Automatic Cleanup finds duplicate contacts with the same name and same phone or email to quickly and automatically combine doubles. Or cleanup yourself, to decide how to combine the doubles into one. 

Find misnamed contacts, such as those with only a first name, to quickly add the missing parts. Even search and replace to get rid of old information that other phones may have left around in your address book. 

Easily email yourself a backup of your address book, delete batches of old contacts with just a few taps, and more.

NOTE: This app works best if your contacts are synced to iCloud. Syncing to other data sources, such as your computer or other servers, may later "fix" the contacts back to the way they were before you cleaned them!
