Time blocking
Your day, pieced into manageable chunks.
Own your time with a tried and tested method. Click and drag on the timeline to create blocks, drag edges to resize, and drop the lightning bolt for a focus block that starts right now — or flip to the seven-day grid when you want to plan the whole week in one view.
- Click-drag to create, drag edges to resize.
- Live red current-time indicator.
- Instant block creator for on-the-fly tasks.
- Seven-day week grid for longer-term planning.
Task mode
A Things-style sidebar that makes lists obvious.
Three columns: lists on the left, tasks in the middle, your day on the right. Switch lists in one click. Drag tasks onto the timeline to schedule them.
- Persistent list sidebar — no hidden dropdowns.
- Drag any task onto your day to time-block it.
- Configurable default duration when dropped.
- Apple Reminders lists appear alongside Chunk lists.
Templates & routines
Save your ideal day. Let it repeat itself.
Capture a set of named, coloured blocks as a template and apply it whenever you need — or turn any template into a routine and pick the weekdays it should run on. Chunk fills the schedule automatically and keeps track of applied days so nothing ever duplicates.
- Create, duplicate, rename, delete templates.
- Apply a whole template or drag single items onto the day.
- Weekday toggles turn any template into an auto-routine.
- Edit the template — every scheduled instance updates.
