SiderealLab iOS Distributed NOW - Measure the Earth rotation locally

Hey PH community! 👋

For those hunters who may not know, the SiderealLab webpage launched before:

I'm Elliott, a previous medical data analyst and a current astronomy and physics UG student (Yr2) from Australia 🇦🇺.

SiderealLab was born from a single cosmic question I asked myself one night under the stars: *"How fast am I spinning on Earth right now?"*

So I built this app—an educational yet elegant tool to calculate **Earth’s sidereal rotation speed at any latitude**.

⚙️ What it does:
- Enter any latitude → get your local sidereal speed (in m/s or km/h)
- Visualize it with a beautiful chart
- Export results as PNG or CSV
- Works completely offline (no login needed)

💫 Upcoming Pro features include:
- GPS-based auto location
- RA/Dec celestial target tracking
- Multi-language support
- PDF lab report generator
- Cloud sync and more!

This is just the beginning. I hope SiderealLab can help students, educators, and stargazers around the world engage with astronomy in a fresh, curious way. 🌍✨

I'd love your thoughts and feedback—and if you try the app, let me know how fast *you* are spinning today 😉

For more instruction information and the Pro version plan, please download it and read the 'User Manual' in the Settings tab.

Thanks!
