Welcome to Co-Do List
A checklist you can shape however you like. To get started:
- + Add item adds a task. Press Return after each one to add the next.
- Tap a task to edit it, and tick it when it's done. Swipe left to delete, press and hold to move.
- The list icon acts on this list — share, paste, print. The cog holds your settings.
- On a phone, add it to your home screen (cog, then Add to home screen). On an iPhone it is the only way reminders can reach you.
Tags, deadlines, timers, templates and the rest are in the guide: cog, then Guide.
Paste a list
Paste a list from ChatGPT, Gemini, Claude, your notes, an email — anything with bullet points. Headings and indented bullets become sections.
Copy this list
Everything below is your list as plain text. Copy it, then use Paste a list on the other list to add it there. Sections, notes, ticks and deadlines all come across; reminders and timers do not.
Templates
A list you reuse: the weekly shop, packing for a trip, etc. Deadlines, timers and completed status are not saved.
Username, email and password
Your username is how other people share a list with you, and everyone on a shared list can see it. Your email address is how you sign in and how a forgotten password is recovered; nobody else is ever shown it. Changing your password here takes effect at once.
Deleting your account removes it and the lists you own, for everyone they are shared with. It cannot be undone.
Guide
The basics
- Tap a task or note to edit it, and tick the box when it's done. Ticked tasks fold away under Done.
- + Add item, then Return after each one to keep adding. Return on an empty one stops.
- Swipe a task left to delete it. Drag the grip on the right, or press and hold, to move it — across sections too.
- On a phone, add it to your home screen: it opens like an app, works offline, and on an iPhone it is the only way reminders can reach you. Cog, then Add to home screen.
Keeping it organised
- Type #tag in a task to tag it. The magnifier finds anything by word or tag, and can show the list in deadline order.
- Paste a list straight from ChatGPT, Gemini, Claude or your notes — list icon, then Paste a list. Copy this list moves one to another list, and Templates keeps one to start again.
Time
- The calendar icon sets a deadline. Tap the date for a time, a reminder, or to add it to your calendar.
- The stopwatch times a task and marks it in progress, or counts down and rings.
- Anything late or due today is counted beside the heading, from all your lists. Tap it to see them.
- With an account: reminders on your phone (Settings), a whole list kept in your calendar app (list icon), and a warning when a deadline clashes with your calendar.
Lists and people
- With an account: up to five lists of your own, and any shared with you, as buttons under the toolbar. Tap one to switch.
- To share a list, tap the list icon, then Share & calendar link, and type the other person's username.
- The brush changes the look, the list icon acts on the list you're on, the cog holds your settings, and the speaker sets the sound.
Add to your home screen
It opens like any other app: its own icon, full screen, and it still works with no signal. On an iPhone it is also the only way reminders can reach you.
- Tap Share. In Safari it is in the toolbar, or behind the ··· button.
- Scroll down and tap Add to Home Screen.
- Tap Add, then open Co-Do List from your home screen rather than from here.

Customise
Ticked tasks gather under “Done” at the end of their section. Off, they stay where they are.
When locked, everyone on this list sees your look but only you can change it.
Sections side by side on a wide screen. Just this device — phones always show one column.
Used the next time you add Co-Do to your home screen — phones never update an icon that’s already installed.
With no logo, the title shows in a display font. Inverting flips a logo’s colours for the theme it would otherwise disappear against — switch theme to set it for the other one.
