SpaceJelly

🚀 WHAT SPACEJELLY DOES
• Nearby launch discovery from trusted schedule data
• Twilight visibility score (0–100%) with clear labels: Prime, Good Chance, Marginal, Unlikely, or Invisible
• Plain-language "why this score?" breakdown (solar geometry, plume lighting, distance, clouds)
• Live countdown, weather context, and look direction (azimuth + elevation)
• Sky Guide compass to aim your phone at the plume
• Smart notifications when a launch meets your score threshold
• Home-screen widgets and Wear OS support so T-minus and score stay on your wrist
• Dark, night-sky UI built for outdoor evening use

OBSERVER-FOCUSED PREDICTIONS
SpaceJelly isn’t just a launch calendar. It combines:
• Your location and distance to the pad
• Launch timing vs local twilight
• Whether the plume is sunlit at altitude
• Trajectory and geometry calculations
• Cloud cover and visibility forecasts

You only get alerted when a visible twilight show is plausible—not for every daytime flight or scrub.

CUSTOMIZABLE ALERTS
• Score threshold (e.g., Good Chance and above)
• Alert timing options from 24 hours out down to T-0
• Scrub and NET time change updates
• Quiet hours support

PRIVACY & PERMISSIONS
• No account required
• Location used strictly for nearby launch distances and sky orientation
