CloudWatcher

Look up at the sky, with new eyes.

CloudWatcher is an all-in-one cloud observation app: identify clouds with AI, learn from a built-in field guide, take quizzes, log every sky you see, and never miss a rainbow or sunset.


Features

Cloud AI Identification
Take a photo and let AI identify it across 10+ cloud types (cirrus・cumulus・stratus and more) with explanations of weather conditions and how to spot each one.

AR Labeling (New)
Point your camera at the sky and tap any cloud. AI labels stick in 3D space so you can compare multiple cloud types at once.

Your Lock Screen and Dynamic Island show what's likely in today's sky in chronological order: rainbows・sunsets・sunrises・halos・cirrus days・stargazing nights.

Smart Sky Alerts (New)
Forecast and sun position predict moments like "Rainbow likely" or "Beautiful sunset expected" and notify you just in time. Each alert type can be toggled.

Cloud Field Guide
The 10 WMO cloud genera with photos・characteristics・meteorological context. Jump straight from the guide into capture mode.

Cloud Quizzes
Three difficulty levels (beginner・intermediate・advanced) to sharpen your observation skills.
