We're excited to announce Folium — a document scanning app for iPhone and iPad that pairs OCR text extraction with multi-provider cloud synchronization. Scan a document, extract the text, and send it straight to the cloud storage you already use.
What Is Folium?
Folium uses Apple's VisionKit to capture clean, edge-detected scans from your device camera, then runs the Vision framework's OCR engine to extract searchable text from every page. Export as PDF or JPG, share via AirDrop or any iOS app, and optionally sync to your cloud storage in the background.
Cloud Sync Everywhere
Unlike single-provider scanning apps, Folium supports six cloud providers out of the box:
- Seafile
- Nextcloud
- ownCloud
- WebDAV
- Dropbox
- OneDrive
Configure multiple accounts, pick the destination when you scan, and let Folium handle the rest. A designated default account handles background sync automatically — your last-used account is always pre-selected for convenience.
Purchase Tiers
Folium uses one-time purchases via StoreKit 2 — no subscriptions.
| Tier | Scans | Price | Cloud Sync |
|---|---|---|---|
| Free | 2 / 30 days | Free | — |
| Basic | 6 / 30 days | $1.99 | Yes |
| Pro | Unlimited | $2.99 | Yes |
Upgrade from Basic to Pro for just $0.99. Scan counts are stored in the Keychain so they persist across app reinstalls.
Privacy First
Like all SSETCO apps, Folium is built with privacy at its core. Documents are stored locally on your device. Cloud sync goes directly to your server — no third-party relays, no tracking, no analytics. You own your data completely.

Under the Hood
Folium is built with SwiftUI and follows the MVVM pattern with CoreData persistence and Swift Concurrency throughout. The cloud sync layer uses a CloudSyncProvider protocol with dedicated implementations for each provider, and an OAuthTokenManager actor handles token refresh for OAuth-based services.
Coming Soon
Folium is currently in development. Check out the app page for the full feature rundown, and stay tuned for the App Store launch.
