Hangs every time I try to create a new contact

A very good piece of software but has always hung when I create a new contact in it. This has been consistent over versions. I then have to quit the app, enter the contact in Google contacts, and restart the app. It then sees the new contact. Good for reference therefore, but impossible to use for populating your address-book manually.

Be carefull with this developer!

They messed Cobook app on Iphone a while ago.
It is look like now it is time to destroy Mac version. It used to be great app, but after company was sold to other developer it goes downhill.
First sentence - All premium features are added to all customer (we pay for premium features 6 months ago).
Second sentence - Facebook and LinkedIn (pemium features) intergration was removed from updated application. We don’t care you pay for it.
They pushing to sell you FullContact app and they try push you to give them all passwords to all your accounts.
I really do not trust them. I suspect they are selling contacts details to Sell Call Centres.
I have so many txts and phone calls from "dealers with hot water” after I naively gave them acces to my contacts on Gmail.
Such a shame...

No longer any use

This used to be one of my favourite pieces of software that worked on Mac and iPhone and integrated with social media. With new owners pretty much all useful functionality removed especially integration with social media. I cant understand the business model that would allow this but have removed software from phone and mac. Back to Contacts for me.
