I first used fedi from Twidere on my phone, but later switched to Fedilab for some reason. It might’ve been that Fedilab had implemented rich text post support, and since I was using Pleroma this was a distinctive feature for me. I’m a bit curious if Twidere has changed or improved much in this time, but I think a sort of “happy accident” of me switching away from it is that I’m even less likely to browse Twitter during my idle time.
Looks to me like it might be DeaDBeeF.
