DivestOS has ceased maintaining Mull if I remember correctly. I use Ironfox on Android now.

I’ve been using KOReader on my phone now, ever since my Kindle one day decided to be unrecognisable on my computer. Couldn’t find a solution to fix it so it became a glorified paperweight.

The screen real estate is slightly degraded, but fuck if I give Amazon any more of my money. Besides, I get to store epubs as epubs instead of converting to that god awful mobi format.
