Cloud Finder: Identify Clouds

Cloud Finder turns the sky into a field guide. Point your camera at the clouds and get a best-guess identification that runs entirely on your device — no internet, no account, no photos uploaded. Spot clouds even with zero signal.

IDENTIFY THE SKY, ON YOUR DEVICE
- Snap a photo and match it against the ten classic cloud genera — cirrus, cumulus, stratus, cumulonimbus and the rest — plus aircraft contrails
- On-device AI model, works fully offline
- Each cloud comes with what it tends to mean for the weather

READ THE WEATHER FROM THE CLOUDS
- Learn what every cloud usually signals — the near-term outlook it tends to bring, and how it evolves
- Will it rain, when, and how much, plus what each cloud means for flying and sky-watching

CLOUD LIBRARY
- Browse all the cloud types, grouped by how high they sit
- Reading their height and shape together is the key to forecasting from the sky

YOUR SKY JOURNAL
- Save every cloud you identify — with the photo, date, and place — and build your own field log

FREE & PRO
Cloud identification and the Cloud Library are free forever. Cloud Finder Pro is a one-time unlock that adds the full Sky Forecast, fun facts, and your saved Sky Journal. No subscription.

A NOTE ON WEATHER
Cloud Finder is a fun, educational sky-watching companion — not an official forecast. AI can be wrong, and cloud types blend into one another. For anything that matters — travel, aviation, severe weather — always rely on your national weather service.

Recent changes:
The quiz is much deeper. It now draws on 456 sky photos instead of 31, so you can play far longer before a picture comes round again.

You can also go past the ten main cloud types. Choose a level: Beginner stays on genera, Intermediate adds species such as Cumulus humilis, and Expert adds varieties such as undulatus.

Thank you to the reader who asked for both.
