Choose where to shoot, plan the light, and remember each visit. Celvion Scout brings location scouting, weather and sun-and-moon planning together for outdoor photographers. COMPARE TWO LOCATIONS Choose two places from existing recommendations and compare the best available shooting times, weather, light, access and safety reminders, and forecast update times. Pick a place to open a Planner draft, then review and save your plan. KEEP SHOOTING RECORDS Save the actual light, up to four reference photos, and parking and walking notes. Reopen a place's records on your next visit, or browse Shooting history in Settings. Records and photo copies stay on this device in your current local profile; they are not synced through iCloud. PLAN LIGHT AND WEATHER Explore curated candidate locations, check Apple Weather, and plan with sun, moon, twilight and Milky Way guides. Set separate camera and subject points and use local times and terrain estimates. AR alignment is available with Pro or Studio on supported devices. PREPARE YOUR OUTING Keep a saved plan and its equipment checklist together in This outing. Packing checks are stored on this device per plan. Turn departure reminders off in Settings while keeping manual tools available. Private spots, collections and plans support optional private iCloud Sync. Pro and Studio add on-demand departure rechecks, darker-site alternatives and downloadable shoot packs. Packs contain prepared planning information and any saved weather with timestamps, not offline maps or live forecasts. Studio also supports batch pack preparation for itineraries. FREE, PRO AND STUDIO Apple Weather access is the same on every tier: up to 10 days and up to 12 selected places per comparison, with shared service safeguards. Free saves up to 10 spots; folders, plans and imports are available on every tier. Pro adds unlimited saved spots, advanced photography scoring, future-date composition planning, AR alignment and one-plan Shoot Briefs. Studio adds multi-location itineraries, route sorting, batch briefs, foreground condition reviews and privacy-safe client delivery. If paid access ends above the free saved-spot limit, existing spots remain available and new saves pause until there is room or paid access is restored. Monthly and annual subscriptions renew automatically unless cancelled. Only Pro Annual offers a 7-day free trial for eligible accounts; other plans have no trial. Candidate locations and forecasts are planning guidance, not guarantees of access, conditions or safety. Check closures, permits, terrain, tides, wildlife and local rules before travel. AR alignment is an estimate. Terms of Use: https://guogxy.github.io/celvion-scout/terms/ Apple Standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
