Awesome. This is a side project I never got around to making myself. For all the questions of "How do you know where the satellites are", there are published TLEs (old punchcard format) that describe orbital parameters, and you can use those to estimate the position within ~10km (good enough for this).

How does it differ from the existing apps that do this?
The no-account and on-device location approach feels exactly right for this kind of app; how often is the orbital data refreshed?
How do you calculate the next passes over a given position?
They dont ...Vibe coded...
where do you get satellite orbits from?
