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, 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. 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.
