Signing a document shouldn't mean printing, scrawling, scanning, and emailing it back. Signed lets you do the whole thing on your iPhone in under a minute — and keeps every document private to your device. Make a signature you're proud of - Draw it with your finger on a smooth, natural canvas. - Type it in one of twelve handwriting styles, or in any font on your iPhone. - Add your company seal or stamp: scan or import it once, then place it like a signature. - Scan or import one you already have. - Save your favorite as the default and reuse it everywhere. Sign any PDF in seconds - Import a PDF from Files, Photos, or another app. - Drop your signature, initials, name, date, text, or a checkmark exactly where they belong. - Your name and today's date fill themselves in, so the common stuff is one tap. - Export a clean, flattened, signed PDF and share it anywhere. Private by design — this is the part that matters Signed is local-first. Your documents, your signatures, your initials — they're stored only on your iPhone. We never upload them, we can't see them, and there's no cloud copy on any server. The paperwork you sign is nobody's business but yours. Made to feel good to use - A calm, clean design that gets out of your way. - Optional Face ID lock for an extra layer of privacy. - Dark mode from day one. Signed is for the everyday signing life — leases, NDAs, offer letters, school forms, waivers, the form your landlord just emailed. Fast, beautiful, and yours alone. What your subscription includes Signed Pro unlocks everything above: saving signatures, initials and seals to your library, and signing and exporting unlimited PDFs. Choose a weekly subscription or a one-time lifetime purchase. You can create your first signature free during setup; Signed Pro is required to keep using the app. The weekly subscription auto-renews until you cancel — manage or cancel anytime in your Apple Account settings.
