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.
I was using Slide for Reddit but the app wasn’t being updated for couple of months and things started to broke up.
Tried a lot of other clients and sync fits right in for me, the beta at that time was even better.
