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 free documents included — never watermarked, unlimited with the one-time unlock
• Unlock unlimited signing with a single one-time purchase. No subscription, ever.
Sign fast. Keep it private. Move on with your day.
