Hey, sorry I forgot to set up notifications for new posts here so I was only recently informed this was here.
We do not have any at present, but I will look into that for you over the weekend and if there is I will try to set something up for you.
I have used Voyager and Mlem on iOS, I believe Voyager is also on Android. There's also Blorp and Interstellar but have never used them, do hear a bit of mention for Blorp however.
