Mobile signingFree and up

Two-thirds of documents are signed on a phone

A guided flow designed for one thumb, offline drafts that survive a dropped connection, and signature capture that behaves like a pen. The person who decides whether a document gets signed today is usually on mobile.

Most signing products are designed for the sender, because the sender is the customer. But the person who decides whether a document gets signed today or next week is the recipient — usually someone who never chose your software, is on their phone, and wants this finished in under a minute.

Documents that behave badly on mobile complete measurably slower. Rebuilding the flow phone-first, rather than adapting a desktop layout downward, is one of the highest-impact things we have done.

How it works

Step by step

  1. 1

    Guided mode moves signers field to field

    A persistent bar shows how many fields remain and jumps to the next one, so nobody has to pinch and pan hunting for what to fill in. The full document stays scrollable — plenty of people want to read what they are signing.

  2. 2

    Controls sit within thumb reach

    Every interactive element lives in the lower half of the screen. Signature capture uses pointer prediction and velocity-based stroke weighting, so the line keeps up with your finger and thins where you move quickly, the way a pen does.

  3. 3

    Drafts survive a dropped connection

    Fill in fields, adopt a signature, place it — all of it persists on-device, encrypted in the keychain-backed store. When connectivity returns the app syncs and completes. Close the app entirely and the draft is still there.

  4. 4

    Long documents get reading aids

    A document outline for jumping between sections, and a reflow view that renders text in a single readable column. Reflow is explicitly a reading aid — signing always happens against the true page layout, so what you sign is what the document says.

Where this matters most

Availability & limits

Free and up

Included on every plan. Recipients never need an account or a paid plan to sign.

Worth knowing
  • Offline drafts require the native app; the browser flow needs connectivity to submit
  • Documents built as scanned images are harder to read on small screens than native PDFs
  • Fields placed very close to page edges are awkward under a thumb — check your own document on a phone

Questions

Mobile signing, specifically

No. The browser flow received the same guided-mode treatment as the app. The app is for people who sign often enough to want offline drafts and push reminders.
