[App] SpaceJelly – see if a rocket launch will make a “space jellyfish” from your location

I made SpaceJelly, a free Android app that finds nearby rocket launches and scores whether the twilight exhaust plume (the glowing “space jellyfish”) will actually be visible from where you are.

It uses your location, launch geometry, solar altitude, and weather — not just “there’s a launch tonight.”

What it does:

• Ranked nearby launches with a 0–100 visibility score
• Countdown, weather, and “why this score”
• Sky Guide compass + elevation so you know where to look
• Alerts before high-probability windows
• Home screen widgets
