About this app

Rooyal Jooker helps you not to miss a single celestial show. The app tracks all the major meteor showers of the year and tells you the exact moment when the sky will present the brightest spectacle.

EVERYTHING IN ONE VIEW

Find out tonight whether it is worth going out to observe. Rooyal Jooker combines key factors into one understandable assessment:
• strength of the meteor shower
• proximity to the peak of activity
• influence of moonlight 🌙

No complicated calculations — just a clear answer: to watch or not.

UNDERSTAND THE SKY

Each meteor shower has its own radiant — a point in the sky from which meteors seem to “fly out” shows:
• the constellation the stream is associated with ✨
• the radiant’s position in the sky
• tips for the best observation

To see the longest and brightest trails, look a little away from the radiant — and the app will tell you exactly how.

DESIGNED FOR OBSERVATION

A simple, fast, and intuitive interface lets you focus on what’s important — the beauty of the night sky.

Rooyal Jooker is your personal guide to the world of meteor showers. Get out under the stars at the right time and catch every moment 🌌
