I really like Stellarium and SkySafari but I felt like these are primarily geared towards exploring the sky but not so much "here are the long list of things I want to see, when can I see them tonight and where". There's also not really a great option I've found that combines sky object planning + location weather details while still being free so I built this.

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

Rocket Journal▲218Hi HN! I just launched Rocket Journal, a voice-first journaling app designed to make reflection as easy as talking. Key ideas: Rant mode — vent freely, no judgment Reflect mode — guided prompts to help dig deeper AI insights — mood tracking, patterns, helpful takeaways Stickers & scrapbook — journaling feels lighter and fun Privacy-first — your data isn’t used to train models I built this because journaling apps often feel like “work.” I wanted something that felt like having a safe, responsive companion for those late-night thoughts or walks outside. I’d love feedback from the HN community:…
