I used Sync for Reddit since 2011 or so, that's how I accessed Reddit 99% of the time. Then they just announced sorry, no more app. For me leaving Sync was akin to leaving Reddit anyway, and someone posted about Lemmy, I learned about the Fediverse, and I came over.
Now when I need to google something and Reddit pops up it feels... overencumbered . Heavy, too much going on with it. Lemmy feels clean, simple, what Reddit used to be. I won't be leaving any time soon.
