How to Sign Agreements on iPhone, iPad, and Android Phones

Direct Answer

To sign an agreement on mobile, tap the signing link received in your email to open the document directly in Safari, Chrome, or any mobile browser. Tap the signature field to draw your signature using your fingertip or stylus, or type your name for an instant calligraphic signature, and tap Finish. SignCEO requires zero app downloads and works smoothly across iOS and Android.

Frictionless Mobile Signing Without App Store Downloads

More than 60% of business contracts and client agreements are opened on mobile devices. When mobile signers are forced to download a proprietary app from the Apple App Store or Google Play just to sign a single document, signing friction skyrockets and completion rates drop.

SignCEO provides a 100% web-native mobile experience. When you or your clients receive a SignCEO envelope, tapping the email link opens the document immediately in the device’s default mobile browser (Safari, Chrome, Firefox, or Samsung Internet).

There are no apps to install, no passwords to create, and no device storage consumed. Signers can review contract clauses, zoom in on text, and complete required fields on the go.

  • 100% browser-based mobile signing with zero app store downloads required
  • Responsive design optimized for iPhone, iPad, Android phones, and tablets
  • Smooth touchscreen drawing pad supporting fingers, Apple Pencil, and styluses
  • Instant document rendering preserving crisp text, tables, and contract margins
