WHY PEOPLE CHOOSE IT • Completely offline — your documents never leave your device • Apple Pencil + finger signatures with pressure-sensitive ink • Initials, dates, checkboxes, text fields, and signature placement • Built-in audit trail: who signed, when, and on what device • Export to PDF or share via AirDrop, Mail, or Files • No subscription, no cloud account, no tracking

PERFECT FOR • Freelancers signing contracts on the go • Small business owners managing NDAs and quotes • Real estate agents handling listing agreements • Anyone who hates uploading sensitive PDFs to a third-party service

HOW IT WORKS

1. Open or scan any PDF
2. Tap "Sign" — draw or type, choose color and weight
3. Drag, resize, and place your signature exactly where you want it
4. Add date, initials, text fields, or checkboxes as needed
5. Export — every action is logged in the audit trail page

AUDIT TRAIL Every signature, initial, and form field is timestamped with the device name. The audit trail page is generated automatically as the last page of your signed PDF — making your signed document review-ready and legally defensible.

PRIVACY • No analytics, no third-party SDKs, no tracking • No cloud upload — ever • No account required • All processing happens on-device
