ToDo Stacker
Stack tasks. Drag. Focus.
Your tasks as physical strips on a control board. Drag what matters to the top, tap play to focus, and watch the timer live on your Lock Screen.
iPhone • iOS 26 • no account required • ToDo Stacker Pro available
Coming soon to the App Store
Your to-do list, reimagined as an air-traffic controller's board.
ToDo Stacker replaces flat lists with something you can feel: every task is a strip — dense with information, color-coded by type and status — stacked on a board you physically reorder. Drag a strip to the top and that's what you do next. No priority fields, no flags, no ceremony. Position IS priority.
FEEL IN COMMAND, NOT OVERWHELMED
- Stacks for every part of your life — Daily, Shopping, Morning, or your own
- Strips show everything at a glance: type, status, priority, due date, sub-tasks, linked calendar events, contacts and reminders
- Drag to reorder — what's on top is what's next
- Sub-tasks nest inside a strip, ready when you expand it
FOCUS IS BUILT INTO EVERY STRIP
- Every task carries its own Pomodoro or countdown timer — no separate screen, no bolt-on. Tap play, and the countdown runs right on the strip
- The timer follows you to the Lock Screen and Dynamic Island with Live Activities — your focus session stays visible even when the app isn't
- Pick a Pomodoro preset (6, 12, 25, 50 or 75 minutes) or set your own — and edit the presets to match how you work
TIMERS AND ALARMS, SAME BOARD
- Standalone custom timers, styled as strips on their own board
- Alarms with weekday repeats, armed with a flick of the strip's toggle
MADE TO STAY OUT OF YOUR WAY
- iCloud sync — your board on every device, automatically
- Import your Apple Reminders lists as Stacks in one tap
- Repeat schedules that respect your intent ("the 31st" stays the 31st)
- Deferred tasks resurface themselves on the right day
- Full VoiceOver support, Dynamic Type, and Reduce Motion respected
- 13 languages: English (UK/US), Afrikaans, Deutsch, Ελληνικά, Español, Français, Nederlands, 日本語, 简体中文, 繁體中文, हिन्दी, Português (BR)
- Beautiful themes, light and dark
Built for people who don't need another list — they need to feel in control. If you think in "what's next" rather than "what's on the list", ToDo Stacker is the board you've been missing. ADHD-friendly by design: visual anchoring, tactile interaction, and focus tools where you actually need them.
