24 alternatives to Astro App
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. The UI's heavily inspired by NINAs sky atlas + Robinhood. Right now you can: View the altitude chart of objects and 3D view Create lists of objects of interest View the annual max/min daily altitude of an object to find the best…
Astro App is a free astronomy planning tool that helps stargazers find when and where to observe celestial objects from their location.

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

I got fed up with the news reader apps out there so I decided to make my own. Its a simple concept where it tracks all your favorite news sources for new posts and the social shares it received. Then it ranks it HN/Reddit style using social shares as upvotes. It's not meant to be alternative to HN, just a focused way to track your favorite sources. Please try it out and let me know what do you think, http://telescope.surf/ Note: you can do 'Add to Homescreen' on mobile to make it as an app. Please leave a feedback or any feature wishlist you may have. Thanks!

Hello HN! My name is Rémy and I recently published an astronomy dashboard where everything is open source: the code of the website, the framework it is based on and the library that computes astronomical data. For the last few years, I have been developing the Ruby library Astronoby (https://github.com/rhannequin/astronoby) with as much dedication and perseverance I could while I don't have any scientific academic background. My end goal was to use this library and build a website that not only provides as much data as possible, but let anyone access and understand how it…
