  Orbit – AR satellite tracker, watch 15k+ objectsJul 2026 · nagylukas.github.io · ▲89

  Hey HN! I made Orbit, an iOS app that allows you to see the satellites, planets, and constellations above you in AR, on a 2D map, and on a 3D globe. The app includes more than 15,000 objects tracked by CelesTrack, together with their pass predictions, descriptions, and detailed orbital data. A searchable catalog of all objects is also available, as well as a built-in chatbot designed to answer any space-related questions you might have. This is my first published iOS app, so any feedback is greatly appreciated! App Store: https://apps.apple.com/app/id6772174570

  Web page that parses and explains the label on a bike tire▲631

  History: Last year I had to replace the tire on my bike, and I was surprised how difficult it was to find a suitable new tire. There were a lot of numbers written on the casing, so I googled what they meant. In the end I was successful, but I didn't want to do the same work again for the next bike after I've forgotten the details. So I wrote this website.
