Sky Guide

Sky Guide turns everyday cloud-watching into a real skill. Built for hikers, photographers, students, and weather enthusiasts, it combines your phone's barometric sensor and camera with a WMO-based Cloud Atlas to help you understand the sky — not just photograph it.

Explore all 10 official cloud genera with clear formation science, altitude bands, and weather significance. Point your camera at the sky, snap a photo, and tag it into your personal, filterable Sky Collection. Watch a live barometric pressure trend graph with rising/falling indicators, and enable optional local alerts for rapid pressure drops that often signal incoming storms.

Sharpen your eye with an adaptive Cloud ID Quiz using spaced-repetition flashcards and progress scoring, or take on the Daily Spotting Challenge to build a streak with gentle reminders. When weather turns serious, the offline Storm Safety guide gives you a lightning-distance timer and a prep checklist you can trust even without signal.

Every sky entry is yours to control: location and date tagging are manual and opt-in, never forced. Export your favorite Sky Collection cards to share standout formations with friends. Switch between hPa/inHg and metric/imperial units, and enjoy a clean light/dark interface designed for quick outdoor reference.

CloudScope works fully offline, contains no ads, and never demands your location. Whether you're chasing storms, teaching a class, or just curious what's overhead, CloudScope gives you real meteorological understanding you can carry in your pocket.
