Mobile signing
Sign on any phone. No app required.
A public link, a few taps, done. Signers never download anything. Managers get a native iOS and Android app for everything else.
Most signing happens on a phone now. We built for that first.
Your signer is at a kitchen table, in a parking lot, on a train. They get a link in an email, tap it, and sign. That's the whole flow. No account, no install, no "scan this QR code to continue on your computer."

The signing flow is your business's first impression. Built for thumbs, not for a focus group.
The first impression
Public link
No account. No app. No friction.
Signers tap the email link and land on the document. The signing page is mobile-first — actually faster on phone than on most desktop signing tools. Decline with a reason if they need to.
- No signup required for signers
- All 11 field types work on mobile
- Conditional fields hide and show as you fill
- Decline with a reason if you need to

Signature pad
A drawing surface that fits a thumb.
Big drawing area. Pressure-aware. Draw, type with a curated handwriting font, or upload an image. The choice persists across the document so the second signature page is one tap, not three.
- Draw, type, or upload
- Pressure-aware stroke rendering
- Choice persists across multi-page docs
- Big enough to not need pinch-zoom
Your signature
Manager-side
Native Expo app for the sender.

- Quick send: PDF + signers + auto-placed field
- From-template flow with role assignment
- In-person handoff with biometric exit
- Push notifications on every signing event
