Priority Zero: To-Do List

A clean to-do list that always shows what matters most - and a gentle chirp that nags your one key task until it is done.

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 a 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
