## What is Signatur?

Sign every document the moment it arrives.

Signatur puts signing, form filling, verification and PDF editing in one app. Quotes, approvals, onboarding papers, agreements — any document that needs your signature gets signed and sent back in minutes. No printer, no scanner.

LEARN IT IN THREE MINUTES
A Guide & Practice file ships inside the app: page 2 is a practice contract. Sign it, fill it, verify it — then sign the real thing.

SIGN LIKE ON PAPER
• Handwritten signature, stamp and date — drop them exactly where they belong
• Face ID confirms before the ink lands, so every signature is yours
• Seam stamp for multi-page documents, one mark across every page pair
• Form fields detected automatically — name, date, company filled in one pass

EVERY DOCUMENT CAN BE VERIFIED
• Signed files carry an invisible watermark — if anything changes, one check reveals it
• Verdicts in plain language: an original is an original, a modified file says so
• Signatures made with other tools are listed, never judged — no false accusations
• Verification is free forever for anyone you send files to, no account needed

MORE THAN PREVIEW
• Merge PDFs, password-protect files
• Redact sensitive content for real — removed, not covered
• Page tools: delete, rotate, reorder
• Scan paper with the camera, stitch chat screenshots into a PDF

BUY ONCE, USE EVERYWHERE
One purchase unlocks iPhone, iPad and Mac. Sign on your phone, keep editing on your Mac.

YOUR FILES STAY ON YOUR DEVICE
Signing, filling, watermarking and verification all happen locally. No account, no upload — there is no server holding your documents, by design.

• Yearly — 7 days free, a reminder 2 days before any charge, billed only if you stay

### 5/5 — Useful signature tools and clever idea.

*2026-07-27*

It is so convenient to use. I think the unique feature is that your signed documents can be verified anywhere; it is such a decentralized verification tool.

## Frequently asked questions about Signatur

## Version history (last 5 releases)

### 1.82 — 2026-08-14

This release rebuilds the bottom bar and turns several things that only looked done into things that are:

• Three equal keys with full names — Signature, Fill, More. Red belongs to the one action in the top corner, and the bar no longer hides itself
• After signing, saved and sent are reported separately: a failed save to Documents says so and offers a retry that only retries the save; the redundant bottom Send is gone — sending lives in the top corner alone
• Nothing clips at the largest text sizes: the bar widens first, then becomes three full-width rows, each with the complete action name
• The drawing toolbar is laid out in two rows, every target big enough for a finger
• The Face ID switch in Settings now actually guards signing — the old switch looked on but stopped nothing; when it's on, signing requires Face ID, and a failed check says so instead of waving you through
• Voice fill recognizes speech on your device only, nothing leaves it; devices that can't do on-device recognition simply don't offer the feature rather than quietly going online
• The paywall promises only what the App Store actually grants: trial days appear only when you're eligible for one, and an unreadable price shows a dash and a retry, never an invented number
• iPad: Apple Pencil signatures land when you tap Done — lifting the pencil no longer commits; keyboard shortcuts act on the current window only; the welcome screen's More offers a menu instead of jumping straight into Settings

### 1.81 — 2026-08-05

A smaller toolbar, a cabinet that says where every document stands, and a few things the app already knew but never told you:

• Three keys instead of four: Sign, Fill, More. Text folded into Fill — one writing tool that fills form fields and types anywhere on the page
• Long-press Sign to stamp the signature you used last; a plain tap still opens the library
• Tapping Sign with nothing on the page now offers your signatures instead of quietly sending an unchanged-looking file — signing without a visible mark is still one tap away
• More is now a grid, and it carries the way out: Documents, Settings and Help without leaving your document
• Every document card now shows its state — draft, signed, re-saved, changed after signing, put away — along with who it's with and when
• Verify says whether you've met a signer's key before, and Settings lists the signers you've met. It answers one question only: same key as last time, or not. It cannot tell you who holds it
• Saved signatures can be renamed, and the user guide can hand you a fresh practice contract whenever you want one
• A damaged document index no longer means an empty cabinet: the list is rebuilt from the files still on your device
• The app's own icons are drawn as one family now, and the dark theme got paper of its own
• Clearer feedback throughout: a spinner while signing, a progress line while converting Word files, a missing required field named on the page instead of behind an alert, and the free allowance says where it stands after you sign

### 1.78 — 2026-08-04

This update smooths out your first minutes — and every verification after:

• New Guide & Practice file: a practice contract ships inside the app — sign it, fill it, verify it, then sign the real thing
• Verdicts with conviction: Signatur-signed files get a clear answer; signatures made elsewhere are listed, never judged
• Importing an already-signed PDF now explains its status, and signing the same file twice asks first
• The top-right button follows the document: Sign before, Send after
• Motion and theme polish across the app

### 1.76 — 2026-08-02

A refreshed App Store presentation makes Signatur's signing, form filling, verification, and privacy features easier to discover.

### 1.75 — 2026-07-27

No release notes.
