- 01
Open the signing link in Safari
When someone sends you a InkRobin document to sign, you receive an email with a link. Tap the link and it opens directly in Safari. No app, no App Store download, no account creation.
- 02
Review the document
The document loads in full in your browser. Scroll through it completely before signing. If you want a plain-English explanation of what you're agreeing to, tap 'Explain this document' and InkRobin will summarize it and flag unusual clauses.
- 03
Tap the signature field
Tap the highlighted signature field (usually outlined in blue or gold). A signing panel opens at the bottom of the screen.
- 04
Draw your signature with your finger
Use your finger to draw your signature in the panel. If you don't like it, tap Clear and try again. You can also switch to 'Type' and type your name in a handwriting font, which often looks cleaner on small screens.
- 05
Tap Finish and you're done
Tap the Finish button. InkRobin records your signature, timestamp, and IP address as part of the audit trail. The sender receives notification that you've signed, and you can download the signed PDF directly from the confirmation screen.
Pro tip
For the cleanest drawn signature on iPhone, rotate to landscape mode before drawing. The wider canvas gives you more room. Alternatively, type your name for a consistently clean result.

Questions
- Do I need to download an app to sign on iPhone?
- No. InkRobin works in Safari and Chrome on iPhone. The entire signing experience is browser-based with no App Store, no installation, and no account required for signers.
- Can I use Apple's built-in Markup tool to sign?
- Apple's Markup lets you draw a signature image over a PDF, but the result has no audit trail and no legal validity under e-signature law. For a legally binding signature, use a proper e-signature tool like InkRobin.
- Will the signed document look the same as on desktop?
- Yes. The PDF rendering and signature placement are consistent across devices. The signed document is identical whether you sign on iPhone, Android, or a desktop browser.
