Hey all! I love reading on my Kobo, especially paired with a self-hosted server that speaks the Kobo sync protocol. The one catch: it doesn't fit in my pocket, so I can't always take it with me.

So I built my own iOS e-reader that syncs reading progress over a few different protocols:

- kosync

- OPDS 1 and 2.0

- Kobo sync

The idea: read a few pages on your phone during a commute, then pick up exactly where you left off on your e-reader at home — and vice versa.

It's called Kios and it's currently in open TestFlight beta. If that sounds useful, I'd love for you to try it. I set up a Discord for issues and feature requests: https://discord.gg/spTFCkhP

Keep on reading!
