Calendars expect everything to have a time. Some things just need somewhere to live until you're ready, and your week shouldn't have to pass through somebody else's server to get there.
Off the anvil
What it actually looks like today. Captions say exactly what each image is.
The real app's week view with built-in fictional sample calendars and the 'Your things' task backlog (three undated tasks).

What it does
Brings Google Calendar, Outlook/Microsoft 365 and iCloud into one view, with two-way edits on writable calendars.
Keeps a task list beside your week: tasks can stay undated, get a focus day or deadline, or be dragged onto the calendar as a time block.
Groups calendars into work, personal or your own contexts, even across accounts.
Day, four-day, week, month and schedule views, with a resizable task pane.
How it's made
One React and TypeScript UI with a shared provider engine, packaged natively for Android, iPhone/iPad (Capacitor) and macOS (Electron).
Installed apps talk directly to Google, Microsoft and Apple. There's no Weekaboo account, hosted database or required server.
Tasks and cached calendars live in a local database on the device. Tasks don't sync between devices yet, but you can export and import them by hand.
