What about reading on a koreader? Is bookbridge still the best bet?

i think smoores response got flagged for some reason, but there’s a StorytellerSync plugin https://github.com/Sirozha1337/storytellersync.koplugin

There are two koreader plugins:

1. StorytellerSync (https://github.com/Sirozha1337/storytellersync.koplugin), which syncs your KOReader progress directly to your Storyteller server

2. Audiobook (https://github.com/stradichenko/audiobook.koplugin), which has a WIP media overlay implementation that works with Storyteller readalouds
