ToDo Stacker
Your to-do list, reimagined as an air-traffic controller's board. Every task is a strip you drag into order — position IS priority.

Position Is Priority
Flat lists tell you what exists. A controller's board tells you what's next. In ToDo Stacker every task is a strip — dense with information, colour-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. Five boards keep everything in reach: Stacks, Timers, Alarms, Progress, and Options.
Everything Lives on the Strip
Dense, Glanceable Strips
Every strip shows its type, status, priority, due date, sub-tasks, and linked Calendar events, Contacts and Reminders. One look, full picture.
Drag to Reorder
What's on top is what's next. Reordering your day is a physical act, not a form to fill in.
Sub-Tasks That Nest
Sub-tasks tuck inside their parent strip, ready when you expand it. Big jobs stay one strip on the board.
A Timer on 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.
Follows You to the Lock Screen
Live Activities keep your focus session visible on the Lock Screen and in the Dynamic Island — even when the app isn't open.
Presets That Match You
Pomodoro presets of 6, 12, 25, 50 or 75 minutes — edit them to match how you work, or set a fully custom duration.
Timers and Alarms, Same Board
Custom Timers Pro
Standalone timers, styled as strips on their own board. Same feel, same drag, same glance.
Alarms Pro
Alarms with weekday repeats, armed with a flick of the strip's toggle.
The Timers and Alarms boards are part of ToDo Stacker Pro — open to everyone during the 14-day trial.
