Rocket Watch

Rocket Watch tracks upcoming rocket launches — with live countdowns, real weather conditions, and a feature you won't find anywhere else: jellyfish-plume potential.

WHAT'S A JELLYFISH PLUME?
During dawn and dusk launches, a rocket's exhaust can climb high enough to catch direct sunlight while the ground below is still dark — creating a luminous, jellyfish-shaped glow across the sky. 321 Jelly calculates whether each upcoming launch falls in that window, so you know when to look up for something special.

FEATURES
• Live countdowns for every upcoming launch, inside 72 hours
• Jellyfish-plume potential for each launch, based on real sunrise/sunset/twilight data
• Current sky conditions (clear, cloudy, or rain) for each launch's own time
• A home screen widget showing the next launch at a glance
• Local notifications at 72 hours, 1 hour, and 10 minutes before liftoff — the 10-minute alert includes real-time sky conditions
• Rocket photos and live broadcast links when available
• No account required, no ads, no data collection

Rocket Watch is free to use. If it helps you catch a launch, an optional paid version unlocks Live Activities, Notifications, and Widgets. Your support helps keep the app supported with new features.

Jellyfish-plume potential is a modeled estimate based on public twilight data, not an official forecast.
