“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.

Crashing recently?


March 5, 2018
This app still only works one time and then crashes when try to sync again the next day even though it has a notification that I have updates for my contacts when is this going to be fixed? Do they want you to pay to upgrade so you can use the app more than one time? If so that’s total Bullsh*t!

Recent updates caused instant crashing again this is getting old!!!

My app crashes and closes as soon as I tap the app button this just started happening within the last week or so I even tried uninstalling and starting over it will sync one time and then crashes after that. Also it won’t sync with Instagram either for some reason I hope they fix this soon. IOS 11 iPhone 6s Plus

Works well for the most part for what it’s supposed to do but...


If it’s going to have pop-up ads, it should at least be able to handle them, there are one or two specific ads that occasionally pop up in this app, that then make the app freeze and I have to force-close it and re-launch it to try again every time.
