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!

Contact High!


This is by far the best productivity app that I have used. I am an institutional broker for a fortune 500 company. I have been syncing contacts from my personal MS-Outlook, employer's MS-Exchange Server, Gmail, iCloud and LinkedIn for several years now. This had left me with hundreds of duplicate and half baked contact records. This was screwing up voice dialing, Siri and simply scrolling through my contacts had become unwieldily. With over 2500 contacts of mostly bad data, iPhone searches were locking up my phone.

I had been dreading trying to manually clean up this mess for obvious reasons. Fortunately, I realized that there must be an app for that and found Contact Clean. It prompted me to easily backup all of my contacts. The initial automatic cleanup function quickly fixed most of my problems. I methodically used the other tools in this app to clean up the remaining issues. Using this app took a few hours to clean up what would have taken me weeks to do manually.

Saved me hours - does what it says

Omid A.

If you got an app to import all your Facebook and LinkedIn contacts to add your contacts images and emails, you might most likely have now ended up with duplicate users. One has picture and email, the other has phone numbers. To manage them manually and merge is just crazy. I started hating my contact list as it had dups and hundreds of contacts making my job hard to find and call a friend quick.
So to enjoy contact list again, I took a risk (small cost) got this app and by a click of a button (literarily) they all got auto fixed. Also it backed up my contacts so I can load it if I ever lose my phone. A great app.

Awesome except for automatic clean


Manual clean looked daunting at first, but when the automatic clean didn't seem to do anything, I used the manual mode to easily merge contacts. The interface was simple to understand, and the only feature I felt was missing was a delete button so that you can just delete bad contacts from this mode.

I then tried the quick delete mode, which implements a long-missing feature of iOS: easy deletion of multiple contacts. When I first got an iPhone it picked up the thousands of gmail contacts google threw its way (before google figured out just because you get an email from someone doesn't mean you want them in your contact list) and I've had them all these years on my 3GS.

So, in 15 minutes, I went from almost 2000 contacts to about 500 "real" contacts.

Free? You have to be kidding. This is one useful tool.
