Pointless Now

Like many other people have said, this app used to be great. Synced perfectly with Facebook, Instagram, Twitter, LinkedIn, and Google. The most important syncable contacts come from Facebook. With no more support for Facebook, the app is now useless. As developers, you have access to information and software changes before the general public does. Therefore, knowing the change to their API and security was coming, you should’ve been proactive and had the update ready to go to maintain support. Just like before a whole-number iOS update. Seems lazy and like you don’t care about keeping the many people who liked this app when it actually did what we wanted it to do. Let’s be real, nobody is going to use this for Caller ID and Blocking, there are leading apps like Truecaller, Hiya, and Nomorobo for that...along with carrier specific apps like AT&T Call Protect. Just give us what we liked the all originally for: working sync capability for Facebook, Instagram, Twitter, and LinkedIn. ALL of them.

Hi ggrudziak,

We apologize for the inconvenience but currently we no longer sync with Facebook due to their API changes.

Our team is working no adding new features for you to enjoy from.

You also have the option to sync with Google+,LinkedIn.Twiiter and Vkontakte.

Please feel free to contact me whenever you like.

Thank you,

“No Contacts to Sync”

It says there are no contact to sync when there clearly is. On top of that, in the app there is a badge notification indicating I should Sync. I’ll get a pop up that says “New Updates to Available”. “There are new updates for your Contacts”.

It didn’t used to say this and I have my contacts downloaded onto my phone VIA iCloud nothing out of the ordinary. Using an iPhone X at the moment. Tried uninstalling / reinstalling, rebooting my phone, etc. I used to love using this app. Hope this gets fixed very soon.

Update: It now works like it’s supposed to no doubt due to an update. Wish it was fixed sooner, but it’s good now. Updated my star rating.

Officially broken

I foolishly bought the premium version of this crApp and it renewed while I believed they were fixing it. Even though it’s SUPPOSED to sync in the background, I get notifications saying there are forty-odd records that need to be synced. To get the notifications to go away, I have to sync REPEATEDLY. And and it sometimes creates duplicate records that later have to be merged (one at a time!). The merged records contain duplicate fields, which which causes Siri to ask which of two or more identical addresses you want directions to. According to customer support, the last update was going to fix this. It did NOT fix it.

If I hadn’t recently paid for another year, this crApp would already have been deleted from my phone and I would be looking for one that actually WORKS. I am about to cut my losses and flush it, anyway.
