Who it's for, and who it isn't
It's for people who get PDFs. Think renters signing a lease, freelancers signing an NDA or SOW, and new hires signing an offer letter. It also suits parents signing school forms and small businesses returning vendor or bank forms. See how to sign a PDF on iPhone.
It isn't for people who send contracts out for others to sign. If that's you, a sending platform is the right tool. See eSign PDF vs DocuSign. If you only sign a single page for someone on an iPhone or Mac, Apple Markup is free and may be enough. See Apple Markup vs a signing app.
