To combat this, I've created a small tool that I call Send HN. It leverages the system share APIs so that you can click the share button in your browser, feed reader, social media app, or really anything, and have what you're looking at sent directly to HN. The app even queries the URL to extract and prefill the page title!
This app is a little different than most apps you've used. Since my goal was to make sharing links to HN as dead-easy as possible, there is literally no UI in the app. When you install it, it won't show up in your app drawer; you'll only see it as a share target. I may add a barebones UI in the future, but for now it has none.
Disclaimer: I actually know practically nothing about dedicated Android app development, so I used Llama 3.3 70B to write pretty much all the code. It's actually quite satisfying for a small project like this to use an LLM to write and refine the code.
The app is GPLv3 and available on GitHub: https://github.com/LorenDB/SendHN
