Select your role using the tabs at the top of the editor — Developer, Product Owner, or Scrum Master. Each role has its own task list and saved progress.

Set your sprint start date in the left-hand settings panel. Once set, day nodes will display calendar dates and the Today button will jump you to the current sprint day automatically.

Click a day node on the timeline to view that day's task checklist. Tick items off as you work through them — progress is saved to your browser automatically and persists across page reloads.

Watch for the bow-wave warning — if you have outstanding tasks from earlier in the sprint, a red overdue panel will appear at the top of the checklist. Day nodes with incomplete past tasks are highlighted in red. Click any warning to jump directly to those tasks.

Track your progress via the green progress bar shown above the task list. Day nodes turn green once all tasks for that day are complete.

Start a new sprint by updating the start date in the settings panel. Use the Reset button to clear all saved progress for the currently selected role.
