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.

Beware of This App If You Use Google Contacts

This app used to allow Google contacts to be the default contacts database. It no longer does and requires that you sync everything with Contacts on the Mac. There are differences in the Mac and Google contacts database formatting which will mess up your contacts. Beware of this. If Google is your primary contacts database this app is no longer an appropriate choice
