SignFast: Sign PDF & eSign

Sign and fill PDFs in seconds, no account, no subscription, nothing leaves your phone.

Most signing apps make you create an account, start a “free trial,” and hand over your documents before you can sign a single page. SignFast doesn’t. Open a PDF, drop your signature, and share it back, everything happens on your device.

SIGN & FILL ANYTHING • Add your signature, initials, text, dates, and checkmarks anywhere on the page • Drag, resize, and place elements exactly where you need them • Undo, redo, duplicate, and delete as you go

MAKE YOUR SIGNATURE, YOUR WAY • Draw it with your finger • Type it in a clean signature style • Snap a photo of a signature on paper — we turn it into clean, transparent ink • Save signatures once and reuse them

IMPORT FROM ANYWHERE • Files, Photos, or your camera (scan a paper document) • Open a PDF shared from Mail, Safari, or any app • Open password-protected PDFs — the exported copy is unlocked

MANAGE PAGES • Rotate, reorder, and delete pages before you sign

PRIVATE BY DESIGN • On-device only — your documents are never uploaded • No account, no sign-up • Optional Face ID app lock and opt-in on-device history

FAIR PRICING • 3 clean documents every month, free — never watermarked • Unlock unlimited signing with a single one-time purchase. No subscription, ever.

Sign fast. Keep it private. Move on with your day.
