Signature - Sign & Draw

Signature is the cleanest way to create, store, and share your personal signatures on iPhone.

Draw with a smooth, pressure-sensitive canvas that faithfully reproduces the feel of pen on paper. Choose from three distinct nib styles — Fountain, Ballpoint, and Marker — each with its own ink character, taper, and opacity. Pick your ink color from a curated palette including black, navy, crimson, and forest green, or dial in any custom color you like.

Set the canvas background to suit your purpose: transparent for clean overlays, white for a crisp document look, lined for a writing-guide feel, or warm parchment for a classic stationery aesthetic.

Every signature you save goes into your personal library, displayed as paper-card thumbnails so you can recognize each one at a glance. Tap any card to view the full detail, rename it, or delete it. Batch-select multiple signatures in edit mode for quick management.

When you're ready to use a signature, share it as a PNG image, export it as a PDF, or send it straight to your Photos library — all from a single tap.
