FormSign fills and signs PDFs entirely on your device — no account, no cloud, no subscription. Open any PDF and it auto-detects the form fields. Tap to fill, add text or checkmarks, and sign with your finger or Apple Pencil. Then flatten into a clean, shareable file — none of it ever leaves your iPhone or iPad. Signing a PDF got turned into a monthly fee. FormSign gives it back: everything runs locally, and you pay once. Free for your first 5 documents, then pay once. No subscription, ever.
Hey Product Hunt 👋
I built FormSign because I was tired of the same pattern: you need to sign one PDF — a lease, a school form, a waiver — and the "easy" app wants you to create an account, uploads your document to a server you'll never see, and bills you $15–20/month forever.
Signing a PDF is a solved problem that got turned into a subscription. FormSign is my attempt to give it back:
→ Everything happens on your device. Your documents literally never leave your iPhone or iPad. There's no backend to leak, subpoena, or breach.
→ You pay once. 5 free documents to try it. No subscription, ever.
→ It's genuinely fast: open a PDF and it auto-detects the fields, you tap to fill, sign with your finger or Pencil, flatten, share. Done in under a minute.
It's built natively with PDFKit + PencilKit, zero third-party SDKs, and no analytics.
I'd love your feedback — especially on the field-detection and the signing flow. What's the most annoying PDF you've had to sign lately? I'll test FormSign against it.
Thanks for checking it out 🙏
Finally a PDF signer that just works on my iPad without making me sign up for yet another subscription. The auto field detection caught every box in a tax form I had been dreading.
One thing I'd love to see is the ability to save reusable templates for fields you fill in often, like your address or signature date. Right now I re-type the same info on every form, and a quick "fill from profile" option would save a lot of taps.
