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 🙏

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.
Great news, Sabri - that's already in there! Tap the ⚙️ and fill in "Your Info" (name, email, address, and more), and those show up as one-tap chips right above the keyboard whenever you're filling a field. Signatures and initials are saved and reusable too, so you're not re-drawing them each time.
Where I think you're pointing - and where you're right - is field-level templates: "on this recurring form, these 6 fields always get these values." That's a genuinely good idea and it's going on the roadmap. Out of curiosity, is it mostly the same handful of forms you fill repeatedly, or lots of different ones with the same personal info? That'd help me build the right version of it. 🙏

@miragagaiyib "finally a pdf filler that does not want my email" might be my favorite sentence of the whole launch 😄 That's the core of it, Miraç - no account, no cloud, nothing leaves your device, ever. Auto-detect + Apple Pencil + file-stays-local is precisely the flow I wanted to feel effortless, so it means a lot that it landed that way for you. Thanks for testing it on a real tax form - that's the true trial by fire. 🙏
