Local Sidereal Time vs Beauty Math

Sidereal helps you track local sidereal time from your current location or any place you want to check. It is designed for people interested in the 13:30 LST window discussed in remote-viewing literature, while also supporting any custom sidereal target you want to follow. Use Sidereal to: View a live local sidereal clock based on your current location Calculate local sidereal time manually from longitude, date, and time Search for a city or address and see the result with map support Generate the next 31 upcoming hits for your selected sidereal target Schedule the next 30 days of on-device alerts Export future times to CSV and export events to your calendar Customize your target LST, alert timing, full-window notifications, night viewing, and map visibility Sidereal starts with 13:30 LST as the default target, but you can change it in Settings to track any local sidereal time. The app includes a trial, with Pro unlocking continued access to advanced tools and planning features.

Beauty Math is an interactive math art museum. See the beauty first—then understand the idea. Wander the Gallery by mood: Inspiration, Zen, Kinetic, and Nature. Or switch to the Laboratory and explore by math branch—shapes, geometry, polar curves, Fourier, calculus, chaos, and fractals. Turn a few art dials and watch equations morph in real time. Smooth motion. No drawing board. Just living geometry. HIGHLIGHTS • 20+ interactive models—from flower of life and rose curves to Lorenz and Mandelbrot • Live parameter tuning with on-screen formulas • Step-by-step derivation mode to reveal how forms are built • Zen Mode for distraction-free immersion • Capture Beauty—save stills, GIF, or MP4 loops to your photos • Multilingual UI (English, Chinese, and more) FREE TO EXPLORE Many galleries are free to browse and play. Chaos, Fourier, and Calculus unlock with Beauty+ (auto-renewing subscription). Dynamic GIF/MP4 exports include a small free trial, then an optional Export Pack. PNG stills stay free.
