Install as an app and use offline

YAPCO is a progressive web app: the browser can install it like a desktop or phone app, and after the first visit it opens and works without a connection.

  • Chrome or Edge on a computer: the install icon at the right of the address bar, or the menu → Cast, save and share → Install page as app.
  • Android (Chrome): menu → Add to home screen → Install.
  • iPhone and iPad (Safari): Share → Add to Home Screen.

Installing needs HTTPS (a hosted site) or localhost. Browsers do not offer it on a plain http:// address in your LAN.

Works offline Needs a connection
Dashboard, designer, preview, content, translations Create PDF (the export service)
Printing from the browser (Print view) Opening the app for the very first time
JSON backups and imports This documentation

The app checks for a new version each time it opens with a connection, and uses it from the next visit on. Your planners are not affected by updates.
