SkySort uses on‑device AI to identify clouds in seconds — no internet required — then logs each sighting with the weather and location in your own private sky journal. Whether you’re a weather watcher, hiker, photographer, student, or simply sky‑curious, SkySort helps you notice more and learn as you go. IDENTIFY IN SECONDS • Snap a photo or import one from your library — SkySort recognizes 12 sky conditions: Cumulus, Cumulonimbus, Stratus, Stratocumulus, Nimbostratus, Altocumulus, Altostratus, Cirrus, Cirrocumulus, Cirrostratus, contrails, and clear sky. • Every result includes a confidence score and an at‑a‑glance quality rating, so you always know how sure the model is. • Identification runs entirely on your device — fast, offline, and private. LEARN THE SKY • A built‑in encyclopedia covers all 12 cloud types: how they form, the weather they signal, and how to tell look‑alikes apart. • Explore 25 weather terms and 6 special phenomena — halos, sun dogs, iridescence, virga, crepuscular rays, and lenticular clouds — with example photos. • Not sure what you’re seeing? The ID Helper walks you through a few simple questions to narrow it down. BUILD YOUR SKY JOURNAL • Every observation is saved with its photo, type, confidence, date, and place. • SkySort automatically records the weather the moment you save — temperature, wind, humidity, pressure, visibility, UV, and cloud cover. • Search, filter, and sort your history, and see all your sightings on a map. • Track your trends: most‑common clouds, average confidence, and recent activity. SYNC, SHARE & EXPORT • Your journal syncs across iPhone and iPad through your private iCloud. • Share a cloud with a ready‑made caption — your location is never included. • Export everything to CSV or a polished PDF report, in Metric or Imperial units. PRIVATE BY DESIGN • Photos are analyzed on your device and are never uploaded to a server for identification. • Your observations live in your own iCloud, not on our servers. • Shared images and captions never include your GPS coordinates.
