How can I sign a document I received by email or from another app?
Locate the attachment in the Mail app or the file in your other app
Open the file in Genius Sign
Tap on the Export button at the top right of the screen. This button looks like a box with an up-arrow.
Choose Genius Sign among the available options
If you don't see the Genius Sign option, you may have to reveal additional options. Also make sure the document is compatible with Genius Sign (PDF, JPEG, PNG, Word, RTF).
