How do I make a handwritten signature on my iPhone?

Short answer: Draw it with your finger on Signed’s smooth canvas, type your name and pick a real handwriting style, or let AI generate one — then reuse it on every document.

You have three honest options, and which one you pick depends on how fussy you are about the result:

Draw it with your finger. The classic. On a phone screen this works better than a mouse ever did — fingers are much closer to pens. Tips: draw bigger than feels natural (it scales down cleanly), use two or three fluid strokes rather than tracing slowly, and don't chase perfection — real signatures are irregular.
Type your name and pick a handwriting style. Fastest way to a consistently elegant signature. Signed renders your name in real handwriting and cursive styles — you pick the one that feels like you. You can also try this free in our browser signature generator.
Let AI generate one. Type your name and Signed's AI designs a handwritten-style signature — not a font, an actual drawn-looking scrawl. Good when your real signature is (honestly) a mess and you want something better.

Whichever you choose, save it once and reuse it — the win isn't the first signature, it's never having to recreate it for every document.
