The signer receives a secure signing link via email or SMS on their mobile device.
Tapping the link opens the document directly in the mobile browser. No app needed.
Scroll through the document, fill in fields, and draw or type your signature.
Submit your signature. A copy is emailed to all parties. Takes under 2 minutes.
SignAndGo works like a native app without the app store. Install it to your home screen for instant access, or just use it in your browser. Either way, the experience is fast and smooth.
PWA technology means the app loads instantly on repeat visits, even on 3G connections. Push notifications keep signers informed without needing a native app.
Every page, every form, and every signing experience is designed to work on screens from 320px to ultrawide. Documents reflow to fit your screen, and touch targets are sized for fingers, not mouse pointers.
The PDF viewer scales automatically, and signature fields are enlarged on mobile to ensure accurate touch input. Pinch-to-zoom is available for detailed review.
Signers receive push notifications when a new document needs their signature, when a reminder is sent, or when all parties have completed signing. No more checking email constantly.
Notifications work even when the browser is closed, thanks to service worker technology. Signers can manage notification preferences from their account settings.
Slow connection? SignAndGo compresses document previews and loads pages progressively. The signing interface remains snappy even on 3G networks.
Documents are cached after first load, so switching between pages is instant. Only the final signature submission requires a stable connection.
Draw your signature with your finger or stylus directly on the screen. The signing pad captures natural handwriting with pressure sensitivity on supported devices.
Alternatively, signers can type their name and choose from generated signature styles, or upload an image of their signature. All three methods are legally valid.
The same encryption and security protections that apply on desktop extend to mobile. All data is transmitted over TLS 1.3, and signing sessions expire after inactivity.
Biometric authentication (Face ID, fingerprint) can be used to access the SignAndGo PWA, adding an extra layer of security on mobile devices.
Long documents are harder to review on small screens. Where possible, keep to essential pages and use clear headings.
On mobile, larger signature fields are easier to tap and sign. SignAndGo automatically enlarges fields on mobile, but placing them with adequate spacing helps.
Many people see SMS before email. Adding a phone number to the recipient ensures they receive the signing link on the device they are most likely holding.
Preview your document on a phone to check that fields are accessible and the document is readable without excessive zooming.
Every field a signer must complete on mobile is a potential friction point. Only require what is truly necessary.
No. SignAndGo is a Progressive Web App (PWA) that works directly in mobile browsers. Signers click the signing link in their email or SMS and sign immediately — no app store download required. Users can optionally add SignAndGo to their home screen for quick access.
Yes. Under the Electronic Transactions Act 1999, the device used to apply an electronic signature does not affect its legal validity. Mobile signatures carry the same legal weight as desktop signatures, and the audit trail records the device type for evidentiary purposes.
You need an internet connection to initially load the document and to submit your signature. However, SignAndGo's PWA technology caches the application for fast loading, even on slow connections. For areas with poor connectivity, we recommend loading the document on WiFi before heading to the field.
SignAndGo works on all modern mobile browsers including Safari (iOS), Chrome (Android/iOS), Firefox, Samsung Internet, and Edge. Any device running iOS 14+ or Android 8+ with an up-to-date browser will work. The signing experience is optimised for both phones and tablets.
