Who it's for, and who it isn't
It's for people who get PDFs: renters signing a lease, freelancers signing an NDA or SOW, new hires signing an offer letter, 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.
