Contacts Cleaner

By Aston Shaheen

Open the Mac App Store to buy and download apps.


Contacts Cleaner analyzes, reports, and fixes dozens of problems with OS X Contacts and Apple Sync Services—problems ranging from the obvious, such as duplicated contacts, to the subtle, such as invalid characters and poorly formatted contact names.

Your contacts are the center of your personal social network, and as such are often synchronized among your Mac, your iPhone, and many other apps, services, and devices. Contacts Cleaner finds and fixes the little problems that can creep in while you're not looking.

Note: Contacts Cleaner currently does not fix contacts hosted on an Exchange server. Contacts Cleaner does work with iCloud.

* Fixed a problem with international codes when fixing phone numbers
* You can now set a default area code to use when fixing phone numbers

Customer Reviews


Contacts and Calendars have always been Apple's joke on us. They were never reliable to begin with. With the advent of MobileMe or iCloud or whatever next they’ll come up with, a bad thing is becaming a nightmare. So I decided to give it a try and bought Contacts Cleaner. I backed up my contacts, terminated iCloud completely and everywhere (iMac, MBP, both iPads, iPhone) and ran Contacts Cleaner. The thing deleted about a thousand duplicates, lost several good contacts and left some others a bleeding mess. But what a relief it was when I saw my Contacts about two thousand leaner. Conclusion: The app is good when you’re looking for someone to do the dirty work for cheap. But don’t count on it for the finer points. These you have to do yourself or look elsewhere. And be prepared to eat some casualties.

Rock-solid support from the developer!

I’ve used Contacts Cleaner since 2010. It has saved hours of work scrubbing and formatting our 4000+ contacts. In the dark days of MobileMe, and even through some abortive attempts at syncing Google contacts back in the day, it has just WORKED.

The team at Spanning Sync were gods when it came to synchronizing calendars, before Apple converted from sync services. Now, they run Spanning Backup cloud backup of your googlesphere, and we trust all our corporate Google Apps data to their care.

Two thumbs up. (I’d give them more, but due to my species, I’ve hit my limit.)

It does what it’s supposed to but could be much better

Contacts Cleaner finds dupes and gives you options to delete or merge duplicates, however you cannot see the duplicates side by side to choose WHICH of them you want to keep. You cannot select what fields you want to merge and how. You cannot choose to bypass certain contacts so that the next time you open Contact Cleaner again, you have to pass those contacts again before getting to duplicates further down the list. If this program were a little more robust (even as robust as Contacts ITSELF is when importing VCARD archives that have duplicates), it would be worthy of 5 stars.
