Open Scanner review
A free, open-source iPhone scanner with OCR, organization, signatures, and PDF export.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Open Scanner is a free, open-source document scanning app for iPhone. It uses the device camera to capture receipts, notes, textbooks, and other paper documents, then stores them in an in-app library. The app also supports automatic text recognition, automatic document naming, page organization, annotations, signatures, PDF export, and sharing. It does not require third-party accounts, making it suited to iPhone users who want a focused scanning workflow without a subscription.
The published product details show a free model with no ads, in-app purchases, or subscriptions. There are no paid tiers to compare, so every listed capability sits within the same offering. iCloud synchronization connects the library across the user’s devices, but iCloud is the only listed integration. That makes the app a natural fit for people already working within Apple’s ecosystem, while users who need broader connections to other services should look elsewhere.
Open Scanner covers the core document workflow from capture through organization and PDF sharing. Its standout capabilities are automatic text recognition, automatic naming, page reordering, annotations, and signature support, giving users more than a basic camera-to-PDF utility. The focus remains narrow: native iPhone scanning with library management and iCloud synchronization. Automatic capture and multi-page scanning are unverified, so users who require those specific workflows should consider an alternative. Choose Open Scanner for free, open-source iPhone scanning; avoid it if Android support or wider integrations are essential.
