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.

BEWARE! Used to work, and there is NO support

I used to love this program. Worked well, but it stopped working (crashed on open) and there is ZERO support. The Customer support email provided is dead - my emails were returned as undeliverable and there is no other way of contacting. Unfortuante.

There’s a learning curve...

Ladies and Gentlemen,

I have been looking for a way to clean my contact list for years. I think I found a keeper. I was a victim of multiple email accounts and mobile phones that kept aggregating information and syncing contact information together, in an unorganized fashion.

Using Contacts Cleaner I was able to clean my 4000+ contact list with relative ease. Be warned, it does have a very quick learning curve, so before you start changing everything read your options carefully. I also highly recommend that you save a backup of your contact list before you start, so you can always fall back on that version if things go wonky. I had to do that once before I fully understood the power of the app.

My advice would be to go through and fix the easy ones where you can change multiple accounts with common rules. The app seperates all of the different errors by category, which is quite nice. Don’t be afraid to commit 2-3 hours to clean your account for the first time. Once it’s clean a simple scan once a month could keep you on track.

I love how clean my contacts are now! Finally!!
