Hey HN, I built an SDK to help me create apps I wanted on my Kobo. My Kobo device has a single core <1GHz processor and 512MB RAM, much less than a Raspberry Pi, but the eInk display and larger battery life opens up a lot of use cases. I have since used it to build an approval sidekick for my Mac's Claude code and codex, a Hacker News Client for Kobo, a Gutenberg reader, an RSS search and reader and more. All the code is in the repo. If you have a different device than mine (Clara BW) would love for you to test it on your device and submit a PR to enable this for more device profiles. Thanks.

I read HN on my phone every day and never really settled on a reader, so I wrote my own and finally tidied it up enough to put out there. It's plain SwiftUI with no third-party dependencies. A few things I spent the most time on: Comments are parsed and drawn as native text instead of being dumped into a web view. Links, italics, quotes and code blocks behave like the rest of the OS, text selection works, and threads collapse instantly. The whole comment tree comes back from the Algolia API in a single request, which felt a lot nicer than walking the Firebase API node by node. Accessibility.…
