Timebox.so is a web-based daily planner built around timeboxing, the practice of giving every task a defined block of time. It is inspired by Cal Newport's book Deep Work and his physical Time-Block Planner. It is made by an indie maker named Rohan, who started timeboxing after reading the book.
The product combines a drag-and-drop scheduler, to-do lists, notes, an activity calendar and Google Calendar syncing in one place. The site positions it for people who want to plan deep work sessions, adopt a maker's schedule and reduce decision fatigue.
Users first build a to-do list, which supports sub tasks and tags. They then drag items from that list into a daily scheduler to allocate time for each one. One user mentions 15-minute steps in the scheduler, which makes blocks quick to set.
Tasks that do not belong in today's plan go into a separate to-do later list. Each day also has a notes area. The scheduler syncs with Google Calendar, so existing events and timeboxed tasks appear together.
The main feature is the drag-and-drop timebox planner. Alongside it are a to-do list with tags and sub tasks, a to-do later list and daily Notion-style notes. One customer singles out the brain dump notes section as useful for planning and rough work.
For tracking, an activity calendar shows to-do completion over time, and the comparison table lists task completion and deep work tracking. Schedules are kept in cloud storage, so past days can be reviewed. Google Calendar sync and a dark mode round out the list.
