I made an iOS HN app to navigate large threads without getting lost
I was struggling with navigating HN discussions using existing solutions, so I decided to implement a completely different approach, think of it as depth-first reading vs breadth-first reading. Visually it looks like swipeable stacks of comments and it offers several advantages over traditional interfaces: - Comment width doesn't get narrower no matter how deep in the comment tree you are - You always see the parent of the comment you're currently reading - Swiping allows you to move in and out of subtrees with animated transitions that you fully control - You can easily skip subtrees that…
In plain words
This iOS app helps users navigate Hacker News discussion threads using a swipeable stack interface instead of traditional nested comments. Rather than reading breadth-first, it enables depth-first exploration where comment width remains constant at any nesting level and parent comments stay visible. Users can swipe to move through subtrees with animated transitions and scroll to skip uninteresting branches. The app includes custom boards, search, in-thread search, anchors, and a reading list, designed to maintain context and reduce disorientation in long discussions.

In the maker’s words, at launch
I was struggling with navigating HN discussions using existing solutions, so I decided to implement a completely different approach, think of it as depth-first reading vs breadth-first reading. Visually it looks like swipeable stacks of comments and it offers several advantages over traditional interfaces: - Comment width doesn't get narrower no matter how deep in the comment tree you are - You always see the parent of the comment you're currently reading - Swiping allows you to move in and out of subtrees with animated transitions that you fully control - You can easily skip subtrees that don't interest you by scrolling As a result it's easier to maintain the context and to keep track of where you are in the discussion tree. The app is fully featured, it does all the things that you would expect it to do, and there's extra: custom boards, search, in-thread search, anchors, reading list, recent items.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
