The app is great for updating photos and blocking spam calls. However, they have changed it to where you need to pay and upgrade to get the same features it use to have for free; such as, scanning social media profiles for new/updated contact photos and merging contacts. When I changed phones a month ago and downloaded the app again, it told me I could no longer sync with FB because of their updated privacy settings. At this point, I may start looking for a new app.

Used to be the best way to organize contacts. Lost Facebook years ago, now lost Linked in too. Latest version throws an error on all calls if you don't want it to filter them which I do not. Took me an hour to figure out the error in my phone app was coming from this app. Permissions are user choice. You have no right to trigger an error condition for a setting. After 10 years I am finally done.

Thanks, Catherine. We’re sorry this update caused call errors when filtering is off, and that Facebook and LinkedIn sync are no longer available. Please email support@sync.me with your device model, Android version, and a screenshot of the error so we can help. Have a lovely day! 💙

The app used to work good but stopped working. The caller ID used to tell me who was calling and whether it was spam. After it stopped working, I uninstalled and reinstalled. It still didn't work and when it did, it told me I had no internet connection. Emailed customer support which took 6 days to reply and they were not helpful. I had deleted the app a few months ago because it wasn't really helpful. I stopped getting spam calls down to about 1 per week. I just reinstalled it recently to sync social media pictures to my contacts. Less than a day after installing, I get spam calls all the time, from all over multiple times a day. I'll be uninstalling again.
