I’m using it. I came from Relay. I like Jerboa because it has two features I really liked in Relay, colour-coded threads for readability, and swiping to get back from a comment section to the main feed. I’m not too fussy other than that (dark mode and small font also appreciated though). It works well for me in general, I can switch between my accounts easily which I like, though there was a bit where my instances weren’t up-to-date enough for the app and notifications have been a bit on/off, but that’s teething problems. It also sometimes forgets my preference for defaulting to all > today, it puts it back on active.
