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.
A friend recommended Reddit, I signed up in 2012 but the interface was… uninspiring. Especially on mobile. Out of curiosity I tried Sync in 2013 because it was getting very good reviews, and immediately preferred it.
I’ve never been a heavy Reddit user, but did most of my usage through Sync. It was just better.
Somewhat ironically I’ve recently been thinking about doing more in some Reddit communities, but the awful behaviour of Reddit means that won’t happen now. So I’m really looking forward to seeing Sync for Lemmy so that I can pursue those goals here in comfort and style! 😉
