Work in progress
Plan only what fits in today.
Ritualivity is an open-source daily planner: each morning you pick the tasks that fit around your calendar, and each evening you close the day with a short review.
Connecting Google Calendar is optional: it shows your events next to your tasks and puts your timeboxes on the calendar you pick (how we use Google data).
We are still building it, so expect missing pieces and things that change.
