Priority Zero: To-Do List

Things to do, in the right order.

Priority Zero is a clean, fast to-do list built around one idea: give every task a priority from 0 to 9, and always see the most important things first. Zero means "do this now" - hence the name.

PRIORITIES FIRST

- Every task gets a priority badge, 0 (most urgent) to 9

- Lists sort by priority by default, so the top of the list is always what matters most

- Also sort alphabetically, by created date, or by due date - per list, the app remembers your choice

A CHIRP THAT KEEPS YOU HONEST

- Pick ONE task and switch on "Chirp at me until this is done"

- The app gently chirps at an interval you choose (every 5-120 minutes), during your working hours only, until you mark it done

- Works with the app closed and the phone locked

- Choose your sound: cricket, bird, beep, singing bowl, wolf howl or dog bark

- A visual reminder flashes in the header at each chirp, and the ongoing notification names the task so it shows on your lock screen

EVERYTHING A TO-DO APP SHOULD HAVE

- Multiple lists plus a combined "All Tasks" view

- Due dates with a smart natural-language engine ("tomorrow", "fri", "3 aug")

- Instant search across your tasks

- A collapsible Done section with one-tap bulk delete

- Quick-add that keeps focus, so you can capture tasks back-to-back

- Share or export any list as CSV

- Dark mode

SYNCED EVERYWHERE

- Sign in with a free account and your lists, tasks and settings sync across all your devices

- Works offline; changes sync when you're back online

WORKING HOURS

- Set your working days and hours; the chirp respects them and stays silent outside them
