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.

Best So Far

I was hesitant to pay for this app, i’ve had several attempts to clean up my contacts and merge between different accounts (google, icloud, etc). It won’t go through your exchange accounts but I was fine with that this was fantastic. 4.99 was totally worth it for this one clean up system. It took me 20 min to clean up hundreds and hundreds of contacts and that was at the same time I was dealing with 3 kids and getting breakfast ready. Perfect! Now pull in exchange and we got the best clean up ever. Definately a need for this when you’ve had several accounts over the years of email and handheld media progression.

One of the Best Apps for Cleaning Up Contacts

I was a bit skeptical as to whether or not the Contacts Cleaner would work to help me eliminate multiple duplicates as well as clean up the formatting of my Contacts. After takeing a couple of passes on the Contacts, I’m pleased to say that this app was well worth the small investment that I needed to make on the purchase. I recommend it highly.

Did what it advertised it would do. Over and over again.

I have only 1,086 cards, not syncing with outside DB, so doesn’t take long for Cleaner to work. Have not had any problems as other below. Merges seems to work without a glitch so far. It’s a time saver.
