The Design App That Actually Closes Deals in 2026
You searched for a design app. Most show you furniture, fonts, and Pinterest boards. The design that actually moves money is the one you put on a contract — your signature. Here's the only app for that.
Why Signature Design Is the Real Design Problem
Designers spend hours picking the perfect font, the perfect palette, the perfect grid. Then they send a $5,000 contract with a typed-out 'Best, Sam' at the bottom and hope the client signs. That contract is the actual deliverable. The signature on it is the actual close. eSign PDF treats signing like a design problem. Pick from Fountain, Ballpoint, Monoline, or Marker pen styles. Draw with Apple Pencil for clean strokes. Type in handwriting fonts that look hand-drawn. Or import a photo of your real signature. Your signature stays consistent across every contract, every invoice, every NDA — same as your brand.
Why Markup, Preview, and PDF Editors Look Cheap
Apple Markup signatures look like a kid drew them with a sharpie. Preview on Mac flattens them weird. Browser-based PDF editors compress your signature into a blurry stamp. None of them give you pen-style control. None remember your signature for next time. None handle multi-page contracts without breaking. eSign PDF is built for people who care how their signature looks. Four pen styles. Save once, reuse forever. Multi-page support. On-device — your contracts never touch a server. It's the design app for the one document that pays you.
How to do it
Open eSign PDF and import the document
Pull a PDF from Files, Photos, email attachment, or scan one with your camera. The Share Sheet works from any app — Mail, Messages, Slack, Notion. No upload, no account.
Design your signature once
Tap Signature → Draw. Pick Fountain for elegant downstrokes, Ballpoint for crisp lines, Monoline for modern minimalism, or Marker for bold presence. Apple Pencil gives you pressure sensitivity. Save it and it's reused across every future document.
Place and resize on the page
Drag the signature where it goes. Pinch to scale. Add date, initials, checkboxes, or stamps wherever the form asks. AI smart detection highlights signature and date fields so you don't hunt through pages.
Export a flattened, tamper-proof PDF
Tap Sign & Export. The signature is permanently embedded — no editor can lift it off. Share via AirDrop, email, Messages, or save to Files. Whole flow takes 60 seconds.
Mistakes to avoid
- 1Using Apple Markup for client contracts — looks unprofessional and signatures can be deleted
- 2Typing your name in italics instead of designing a real signature — clients notice
- 3Using a free browser PDF tool that uploads your contract to a stranger's server
- 4Redrawing your signature every time — eSign PDF saves it once and reuses forever
- 5Forgetting to flatten the PDF — unflatened signatures can be removed by the recipient
The App for People Who Care How Their Signature Looks
eSign PDF is built for designers, freelancers, and small business owners who treat every touchpoint as brand. Pen styles for the stroke that matches your vibe. On-device privacy for the contracts that matter. Multi-page support for the leases and NDAs that need it. Free to try. No account.
Learn more about eSign PDF →FAQ
Is this a design app or a signing app?+
Both. eSign PDF treats your signature as a designed asset — four pen styles, handwriting fonts, import-from-photo. Then it puts that signature on PDFs with form fields, dates, stamps, and multi-page support.
Will a designed signature hold up legally?+
Yes. Electronic signatures are valid under the ESIGN Act (US) and eIDAS (EU). Drawn, typed, or imported — all carry the same legal weight as pen-on-paper. eSign PDF flattens the document so the signature can't be tampered with.
Can I use Apple Pencil for the signature?+
Yes, and it's the best way. Pressure sensitivity gives you real ink-like strokes. Fountain pen style with Apple Pencil looks indistinguishable from a real pen signature.
Does my contract get uploaded anywhere?+
No. Everything runs on-device. No server uploads, no cloud processing, no account required. Your NDA, your lease, your contract — they stay on your iPhone.
