So I've been using the #Rodentapp for a bit and it lacks basic features like a follow button on profile, multi-account support, etc. but one feature I do like is the the "no-fomo" button that basically keeps track of all the posts I might've missed out. I think it's better than lists most of the time. There's way too many accounts and hashtags I follow but it helps me keep track of what I want to focus on for that moment.
I wish it was open-sourced or more apps used a similar no-fomo function.
#Moshidon is probably my current favorite app so far. I do occasionally use #OpenVibe more for crossposting. #Fedilab is decent, I used that for awhile. #Phanpy and #Elk are great web interfaces, I probably use Elk more often simply for desktop view of #Mastodon.
This is coming from an #Android user so I can't really tell how #iOS crowd is doing.
