What's New in Signatur

1.81

August 5, 2026

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
