Customer Reviews

Whatever happened to such a good app?

After the recent upgrade, I cannot search for names anymore. I type the first letter and it finds the one listing with just a one-letter name. Then I type the second letter of the name and there are, according to Cobook, no listings that start, in this case, with “st”. Absurd.

So sad. I used to think this was one of the best apps around - it did what it said it would do. Now, it’s not even a one-star. And it no longer syncs with my phone app. I deleted Cobook’s new iPhone app months ago. It was terrible and did not sync with anything. Changes stayed only within the new app.

Don’t buy this one and don’t support the company that bought Cobook and turned it into trash.

Why I use Cobook

So far, I have found it impossible to pair my iPhone with my Mac while running Yosemite, a situation that is affecting many other Mac users, and Apple does not appear in any great hurry to fix this problem. Meanwhile the Cobook people have fo und some way to link to my iPhone that does not depend on Bluetooth, so it is currently the only way I can dial numbers from my contacts list. This one feature alone makes it an invaluable tool.

Stay away from it!

When this application was released it was one of the best for contact management. But since it became Full Contact, things started to be a nightmare. It damages my contacts adress book. Upgrading to Full Contact is a full fonctionalities regression. I spent so much time with the support trying to resolve my issues and I got were excuses.
Unfortunately most of what they are proposing does not work properly. You will end up with duplicates, missing information, contacts that disappear….

If you want to keep your adress book in a good health, stay away from this application!
