James here (creator of Hazumi for HN), after years of working on Hazumi for iOS/Apple Watch, I finally brought all the app's features to Web with tons more that I think you're gonna love
Radar
- watch any post for changes, you get a browser push notification
- set a custom topic or select from what's there, when it's posted you get a browser push notification
Profiles
- you can view any profile and browse their latest activity, posts, comments and stats
Feeds
- add custom RSS feeds to your home page
- add an automatically refreshing HN search feed for topics your interested in on HN
Posts
- each post is enriched with SEO metadata pulled from the linked site
- AI summary of the story too
Weekly digest
- an in app weekly newsletter (automatically compiled top weekly stories and their summaries)
Bookmarks
- not much to say here but collect stories and organize them as you want
I'd love to hear what you think, how I can improve it, what you want added
Thanks!
James
