Everything you need to go paperless.
Aim at any document and tap. The app detects the edges automatically and captures a perfectly cropped scan.
On-device OCR turns any scan into editable, searchable text. Works on printed text, handwritten notes, invoices and more.
Edge detection finds document borders precisely. Adjust by hand if you need to, and enhance with colour filters and brightness.
Scan several pages in one session and combine them into a single PDF. Reorder, rotate, crop or delete pages before saving.
Annotate documents, add digital signatures, insert watermarks and highlight what matters, right in the app.
Share by email or AirDrop, save to the Files app, or send to any other app on your iPhone with one tap.
