Features

Your private life deserves a space of its own. Écrin brings your photos, videos, documents and notes together in a protected personal space on iPhone and iPad. Organize what matters, keep control of your files and choose the right plan during setup. FREE WITH ADS • Add, view and edit your personal photos, videos, documents and notes without an item limit imposed by Écrin. • Organize photos and Live Photos into albums, find your favorites and keep documents and notes in their own folders. • View documents, write notes, take photos and record videos directly in the app. • Protect access with a passcode and, if you wish, Face ID or Touch ID on compatible devices. Free: banners in lists and album grids, including Imports, and occasional full-screen ads on returning to a main list after viewing. Open content stays ad-free. Ad choices and reporting are in Settings. Declining tracking does not block Free access. No personal content is sent to advertisers. YOUR FILES REMAIN YOURS Export your own content as a ZIP archive, with or without a password, to a location you choose. Keep your album and folder organization, stored original files and available metadata. Exporting, deleting and restoring your personal files from an existing backup remain available without a subscription or time limit. Restoration requires the backup’s passcode or password. Exporting shared content depends on the permissions granted by its owner. PREMIUM: NO ADS, WITH ADVANCED FEATURES • Use Écrin without ads. • Create encrypted backups manually or automatically on your device, in your iCloud, or both. Check each copy’s status separately. • Access your private space on compatible devices with iCloud synchronization. • Share albums by invitation and manage participants and export permissions without giving access to the rest of your space. • Use a separate decoy space and an access-attempt log. FAMILY: PREMIUM FOR YOUR LOVED ONES The Family plan includes all Premium features and lets you share the subscription with up to five other members through Apple Family Sharing. Everyone keeps a private space: sharing a subscription does not automatically share content. MAKE IT YOUR OWN Choose a theme, light or dark mode, an alternative app icon and a list or thumbnail view. Écrin follows your device language or your choice in Settings. No Écrin account is required. SUBSCRIPTIONS Premium and Family are available monthly or annually. A 14-day free trial is available to eligible customers under the terms shown before purchase. Backup creation, synchronization, sharing, the decoy space and access-attempt log require an active subscription. Screenshots may show Premium features. After expiry, your personal content remains usable in the free plan. Albums you shared become private, and you leave received shares when a connection allows access rights to be updated. Payment is charged to your Apple Account when you confirm your purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel your subscription in your Apple Account settings. Prices and offers are shown before purchase. Unlimited items do not include additional storage: capacity depends on your device and iCloud account. iCloud transfers require a connection; timing depends on the network and Apple services.

The call

The clearest difference is ads: PDF Reader PDF Viewer at none against Écrin's shown. PDF Reader PDF Viewer also leads on iOS requirement (13.0 vs 17.0). Écrin's advantage is update cadence (every 5 days vs every 3 weeks). On price, in-app purchases and device support there is nothing between them.
