Customer Reviews

can it be worse now ?

Since cobook has been bough by full contact this app is worse every update
Now your facebook and linkedin contacts are no longer supported, to be fair they give you the warning and the reason but I still don’t understant the marketing management of this app? Do they understand those are major contact source for a lot of people ?
their politic behind the other source are also confusing, if I link my tweeter account they can post on my behalf ?? not sure i want to do that...
I guess i’m going to make some room on my dock
See you next time when other decisioin will be made.

Worse and worse

I agree with the general tenor of the latest reviews here. I used to love this app. The new version is extremely buggy - can’t even add a new contact at the moment without the app crashing. I’m removing the app both from my computors and all moble devices. No added value anymore, just insecurity as to whether the app is syncing properly or not (I WILL not pay $99.- dollars a year to get real time syncing I get for free on iCloud) and irritation.

Sad - this app is dead

So sad that an app which was so highly rated can die so quickly when it joins another company. And the Full Contact version is full of BEWARE reviews for Mac. Oh well — I switched to Busy Contacts and love it. It’s just doing what Apple Contacts should already be doing, but until Apple gets it together, Busy Contacts is great.
