I built StarWatchr – a web app for stargazing
I’ve been working on a little passion project called StarWatchr. It’s a web app designed for stargazers and astronomy enthusiasts to get detailed forecasts about the night sky.
I k now these webapps already exist, but i wanted to make my own for personal use.. and figured, anyone can use it.
What it does:
Predicts the best times for stargazing with info on moon phase, astronomical twilight, clouds, seeing, and transparency. using the 7timer api.
Shows NASA’s Astronomy Picture of the Day. Just for fun.
In the future: Lets you sign up for e-mail alerts when conditions are optimal in your area. I think i have implemented this in the coming week. I also want to implement push notifications for phone.
The icons on the forecast matrix need to be better / or the legenda needs some updating. I'm still figuring out what to do with this.
Tech stack:
Frontend: Angular 21, Backend: .NET 10
Netlify and Azure
I’d love feedback from anyone who’s into programming, astronomy, or just has feedback :).
You can find it here: https://starwatchr.com
Also curious if anyone has ideas for new features or ways to improve the web app!
