Shadow Chaser - Bus Shadow Map

[NEW] WHAT'S INSIDE • Real-time sun position — calculates azimuth and altitude for your exact time and location, then maps it against the bus's heading to tell you which side is shaded • Full Hong Kong coverage — KMB, CTB, NLB, GMB (green minibus), Light Rail and ferries, with live ETA powered by data.gov.hk • 3D building-aware shade prediction — uses Lands Department 3D building data so tall buildings actually cast shade on your stop, not just empty sky • Interactive bus seat diagram — colour-coded zones show sun-exposed and shaded seats at a glance • UV index and weather — know how strong the sun is before you step out • Saved routes — bookmark your daily commute and jump straight in next time • Gamification — log the sun-minutes you dodged, build streaks, level up and unlock badges Bilingual — 繁體中文 and English, switch any time Privacy-first — no sign-up needed; your GPS coordinates stay on your device Got feedback?
