FineScanner iOS supports useful tools: a signature, a marker, a pen, text addition, and a patch tool. Add a signature to an agreement, highlight the key points with the marker, or hide confidential information without leaving the application. These features will work not just on the latest version of the operating system, but even on iOS 9! So:
Open any document in FineScanner and select the page you want to edit.
Tap the “Annotate” button and add marker, signature or whatever you need.
Tap the “Save” button and the modified page will be saved as a separate document.
