How it works

  1. Create a group

    One tap. No sign-up, no app to install.

  2. Send the link

    Drop it in your WhatsApp group. Friends open it on their phones.

  3. See when you’re all free

    Everyone adds their CUSIS timetable, and common free times show up straight away.

Your screenshot never leaves your phone. We only store busy times, and groups auto-delete after 30 days.
