SIGNA · ACROSS DEVICES

Downloads & updates

Install the web app

Desktop and mobile browsers can install Signa. Offline assets are downloading when supported. Cloud documents and API responses are never cached for offline use.

Use your browser’s Install app command. On iPhone/iPad, open in Safari and choose Share → Add to Home Screen.

Open private device workspace

Offline device mode provides limited Free features and an encrypted local vault. Paid cloud services require a connection. Different app/browser origins have separate vaults; keep an encrypted backup before moving between them.
