Every cloud tells a story. Log what you see, learn what it means — no account, no internet, just your sky. Look up. Stratus turns every glance at the sky into a personal cloud archive — from towering cumulonimbus on a stormy afternoon to delicate cirrus filaments at 40,000 feet. No account. No internet. Just you and the sky. — KEY FEATURES — • Field Log — Record unlimited cloud sightings with date, cloud type, location label, sky color (6 options), and freeform notes. Swipe to delete entries you no longer need. • 10-Cloud Reference Catalog — Browse all 10 standard cloud genera: cumulus, cirrus, stratus, cumulonimbus, altocumulus, altostratus, cirrostratus, cirrocumulus, nimbostratus, and stratocumulus. Each entry shows altitude range, cloud family, and a practical weather hint. • Family Filter — Narrow the catalog to just the Cumulus, Cirrus, Alto, or Stratus family with a single tap on the filter chips. • Cloud Detail — Tap any catalog entry for a full-screen profile: altitude, family badge, and the weather pattern it typically signals. • Atlas — A monthly calendar density grid shades every day by how many clouds you logged. Navigate backward and forward through months to spot your most active spotting periods at a glance. • Sighting Detail — Tap any log entry to review the full observation: date, location, sky color, your notes, and the matched cloud profile side by side. • Offline First — Everything works without a network connection. Your data stays on your device — no sync, no tracking, no ads. • Ready on First Launch — 15 sample sightings are pre-loaded so you can explore the app immediately and see exactly how entries look before adding your own. Start your sky journal today. The next interesting cloud is already forming overhead. — Stratus Cloud Journal PREMIUM — A Premium subscription unlocks the complete Stratus experience: unlimited cloud sightings and field notes, the full ten-genera reference atlas, your monthly density atlas, and an entirely offline, ad-free environment — everything you need to keep a faithful record of the sky.
