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 T-10 minutes, T-60 seconds and liftoff — plus a T+4 minute alert on jellyfish launches. With your permission, your approximate location (which stays on your device) limits alerts to launches close enough to actually see • Rocket photos and live broadcast links when available • Share any launch with one tap • 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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
