Mine is originally using Baconreader while in the dorm community bathroom doing a deuce and seeing a mention of Sync. Installed and instantly became a user. Later on I had a problem with the app because I was running beta Android. Reached out to the dev and after a few fix attempts an update was posted that fixed the issue. To get that kind of support is rare and is why I have continued to stand by Sync all these years.
When I got my first smartphone with a reasonably large screen I started using Reddit apps. I pretty much tried them all and eventually settled on Sync. I’ve been using that exclusively for almost ten years now. So now I just hope we’ll get a kbin/lemmy Version of Sync soon. I’ll be happy to buy it again.
