DayStack: To-Do & Pomodoro

DayStack puts your to-do list, a pomodoro focus timer and a day planner in one calm app. Plan the day, then focus.

TO-DO LIST
Tasks with subtasks, priorities, due dates, reminders, tags and projects. Switch between a list, a board and an Eisenhower matrix that shows what to do first. Quick add reads as you type: "Call mom tomorrow 7pm #family !high" fills in the date, time, tag and priority.

FOCUS TIMER
Pomodoro presets 25/5, 50/10 and 90/20, or your own timing. Auto-start the next session, add a minute to a break, skip when you need to, and pick an ambient sound. An alert tells you when the session ends.

PLANNER AND CALENDAR
Block time on the day timeline, see your week as a grid and the month at a glance. Drag a task onto a day to move it. A short morning flow helps you pick today's three.

STATS, STREAKS AND A WEEKLY REVIEW
Focus time, tasks done and your streak, with a 26-week heatmap. Each week a review shows what you finished and carries the rest to next Monday.

WIDGETS
Today's progress on your home screen, plus, with Pro, your list with check-off, a one-tap timer start and your streak. iPhone widgets need iOS 17 or later.

PRIVATE AND OFFLINE
No account and no sign-up. Your tasks stay on your phone and everything works offline. Backup and restore, light and dark themes, phone and tablet, 30 languages.

DAYSTACK PRO
An optional upgrade removes the ads and unlocks unlimited projects, tags and time blocks, every ambient sound, week, month and all-time stats, and every widget style.
