Thats my app.

* you can change the accent color and there is a night theme

* Web version doesn't have a login option

* You can download iOS, Android, Mac, and Windows mobile and desktop version from https://hn.premii.com/about/ . You can login, upvote, downvote, reply etc.

Web version uses YC firebase api, and it is usually slow.

Downloadable version scraps YC site, and its generally faster.
