About this app

Sign+ turns your phone into the fastest way to sign, fill, and certify documents — with a signature that actually looks and feels like ink on paper.

Stop printing, scanning, and faxing. Open any PDF or form, drop your signature, and you're done in seconds.

✍️ REAL-INK SIGNATURES
Draw with a signature engine that responds to your speed and pressure — wet, flowing ink that dries on the page. Or type a signature, or import one from paper. Save signatures to a secure vault and reuse them on any document.

📄 SIGN ANY PDF OR FORM
Import PDFs from Files, Drive, email, or the share sheet. Fill text fields, add dates, check boxes, and place initials. Smart field detection finds the signature lines and form fields for you.

🖊️ FILL & SIGN, BEAUTIFULLY
Drag, resize, and snap your signature to the line. Nudge it into place. Flatten and export a clean, signed PDF that opens anywhere.

✅ CERTIFIED & TAMPER-PROOF
Every completed document gets an audit certificate — original and signed document hashes, a signing timeline, and a tamper-evident record. Court-ready proof on every signature.

📷 SCAN TO SIGN
Scan paper with your camera and sign it on the spot — no printer, no desk, no fax.

👥 REQUEST SIGNATURES
Send a document for others to sign, set the signing order, and track who has signed.

🔒 PRIVATE BY DESIGN
Local-first. Your documents stay on your device unless you choose encrypted cloud backup.

Whether you're signing a contract, an NDA, a lease, a tax form, an offer letter, or a permission slip — Sign+ is the fastest, most beautiful way to get it signed.
