SignFast: Sign PDF & eSign

About this app

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.

Fixed “Save to Files”: your signed PDF was saved correctly, but the app behaved as if you had cancelled — no confirmation screen, and the export was not recorded. Saving now completes properly and confirms.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
