Stuck on something?
Just ask.

Just One is made by one person. Write to me and I will write back — usually the same day, always within two business days.

Email: info@sambruneau.com · Cost: the app is free, and so is support.

1. How Just One works

Most to-do apps show you the pile. Just One keeps the pile and shows you one card.

  1. Add everything. Tap the add button and put in as much as you like. Titles, notes, due dates, subtasks, repeats.
  2. Open the app and see one task. That is the Focus screen. There is no list on it, on purpose.
  3. Finish it or skip it. Swipe right for Done, left for Skip. Skip sends that task to the back of the line and shows you the next one. Nothing is lost, and nothing is judged.
  4. Organize elsewhere. Editing, reordering, completed tasks, and settings all live on their own screens, away from Focus.

Everything after this page is detail. If you only ever add tasks and swipe, you are using the app correctly.

2. Using the app

Where is my list?

Open Manage Tasks from Settings. Everything is there: edit, reorder by dragging, enable, disable, delete. The Focus screen deliberately never becomes a list, because the list is the thing that makes a to-do app tiring.

What does Skip actually do?

It moves that task to the back of the current queue and shows the next one. The task is not deleted, not marked done, and not penalized. Skipping is a normal, expected way to use the app.

Skips last for the current pass only. Changing the queue order, the focus window, or the list clears them and starts again at the first task.

Can I change the order tasks appear in?

Yes. Settings gives you three orders:

  • In Order — your manual order, top to bottom. Drag to rearrange it in Manage Tasks.
  • By Due Date — dated tasks first, soonest first. Undated tasks come after them.
  • Random — a shuffle, reshuffled when you finish a task or start a new session.
What is the focus window, and why did tasks disappear?

The focus window narrows the queue to what is due soon. It is separate from the order, so you can combine any window with any order.

  • No filter — everything active.
  • Due Today — tasks due today or earlier. Overdue tasks are included.
  • Due This Week — tasks due on or before the end of this week.

Both windows hide tasks with no due date. If your list looks empty, this is the usual reason. Set the window back to no filter in Settings.

Can I keep work and home separate?

Yes, with lists. Each list has its own queue, so Focus only ever shows you tasks from the list you are in. Switch lists from the list picker. Which list a device is showing stays on that device, so your Mac can sit in Work while your phone sits in Home.

How do subtasks work?

A task can hold a short checklist. Tick subtasks off in Focus as you go. Completing the parent task marks every subtask done, so a finished task never leaves open steps behind.

How do repeating tasks work?

Set a repeat in the Add or Edit screen: daily, weekly, monthly, or yearly, every one or more intervals, optionally ending on a date or after a number of times.

Choose what the next date is measured from:

  • From the schedule — a fixed rhythm, like every Monday. The schedule keeps time whether or not you did it.
  • From completion — a floating rhythm, like 90 days after you last did it. The clock restarts each time you finish.

The next occurrence appears only when you complete the current one. Leave the app closed for a month and you will not come back to thirty missed copies. That is deliberate.

Where do completed tasks go?

To the Completed screen. They leave the Focus queue immediately and stay available to look back at or restore.

How does the streak work? Can I turn it off?

A streak counts consecutive days on which you finished at least one task. It is shown in Settings and mentioned once when you clear your queue. It is reflective, not a lever: the app has no "don't lose your streak" warnings, no goals, no scores, and no red badges. Break it and the app will not mention it.

I prefer buttons to swiping. Or the other way round.

Settings has a Done & Skip preference: swipes only, buttons only, or both. If the swipe directions feel backwards, turn on Swap swipe direction.

The Focus screen feels too busy, or too bare.

Change Focus Mode in Settings. Zen strips the card to the task alone, Compact fits more on screen, and Balanced sits between them. It is a display setting, so each device can differ.

Can I change the color, or the icon?

Pick any of thirteen accents in Settings. The Home Screen icon changes to match. Appearance is separate: System, Light, or Dark, set per device.

How do I see the introduction again?

Settings has How Just One works for the short version and Full Tutorial for the guided walk through the app. Replay either as often as you like.

3. Sync and backups

Does Just One sync between my devices?

Yes, through your own iCloud account, with no account to create and nothing to switch on inside the app. Sign your devices into the same Apple Account and the app keeps them in step. Tasks, lists, and your accent travel. Display settings such as appearance, focus mode, and which list a device is showing stay on each device.

How do I know sync is working?

Settings shows one quiet line. It says one of these:

  • Synced just now, or Synced 5 minutes ago — everything is up to date.
  • Syncing… — a change is on its way.
  • Offline changes saved — your edit is safe on this device and will go up next time it can.
  • Sign in to sync across devices — this device is not signed into iCloud.
  • Sync paused — data too large — see the fix below.

You will never be asked to resolve a conflict. When two devices change the same task, the most recent edit wins and a deletion always beats an older copy coming back.

Do I need an account or a subscription?

No. There is no sign-up, no password, no subscription, and no in-app purchase. Just One is free.

How do I back up my tasks?

Settings, then Export backup. The share sheet opens and you choose where the file goes — Files, Mail, anywhere. The file is a plain, readable snapshot of your tasks, lists, and settings. Keep it wherever you like; the app does not keep a copy.

How do I restore a backup, and will it wipe what I have?

Settings, then Restore from backup. Choose the file, then choose what happens to what is already on the device:

  • Merge — combine the backup with your current tasks. Nothing is thrown away.
  • Replace — the backup becomes the whole list.

Either way the app saves a safety copy of your current state first, and it refuses files that are not Just One backups, so picking the wrong file cannot wipe your tasks.

Is there an Android or Windows version?

Not today. Just One is an Apple-platform app: iPhone, iPad, Mac, Apple Watch, and Apple TV. Sync, widgets, the watch app, and the share extension are all built on Apple frameworks, so a version for another platform would need a different way to move your data between devices.

Ask for it anyway if you want it. Knowing how many people are waiting is how that decision gets made.

4. Reminders

When does Just One notify me?

There are three kinds, and each can be turned off separately:

  • Daily reminder — one gentle nudge on days when you have something waiting. It arrives at a varying time between 9am and 9pm, and it is skipped entirely once you have finished your one thing for the day.
  • Scheduled-time reminders — for tasks where you set both a date and a time.
  • Milestone moments — occasional, quiet acknowledgements, such as your first completed task.

No counts, no digests, no badges, no sounds. Tapping any of them opens Focus.

How do I turn reminders off?

Settings, then Notifications. Turn off Enable notifications for all of them, or switch off Daily reminder, Scheduled-time reminders, or Milestone moments one at a time.

Can I hide task names on my Lock Screen?

Yes. A reminder set for a specific time names the task, so it can appear on a locked screen. Open the iOS Settings app, then Notifications, then Just One, and set Show Previews to "When Unlocked" or "Never." The daily nudge never names a task.

5. Watch, widgets, Mac, and TV

What can the widgets do?
  • Current Task — your one thing, with Done and Skip you can tap without opening the app.
  • New Task — straight into adding something.
  • Due Today — what is due today.

Each one is set to a list of your choosing: hold the widget, tap Edit Widget, and pick. There are Lock Screen sizes and, on iOS 18 and later, Control Center controls for New Task and One Thing.

Can I add a task from another app?

Yes. Share text or a link from any app, choose Just One in the share sheet, and it becomes a task. Siri can also add a task, ask what your one thing is, and mark it done.

What does the Apple Watch app do?

It shows the current task, its due line, its position in the queue, and its subtasks, with Done and Skip. You can switch lists and tick subtasks off. Your iPhone stays in charge of the data, so the watch is a companion rather than a separate app.

Tap Done out of range and the watch holds the action, then sends it when the two reconnect. Adding tasks on the watch is not supported yet.

What does the Apple TV app do?

It is a focus companion, not an editor. Current task, Done, Skip, Undo, list switching, and a few settings, laid out to read from across a room. Add and edit tasks on your phone or Mac; they arrive through iCloud.

Is the Mac app the same app?

It is a native Mac app rather than a stretched phone app, with real menus, keyboard shortcuts, and window behavior. The focus loop, lists, subtasks, repeats, Completed, backups, and iCloud sync all match the iPhone.

6. Privacy, price, and accounts

What does Just One collect about me?

The public App Store release sends us no task data and enables no analytics, advertising, or tracking. There is no account or task server of ours. Your tasks live on your device and sync through your own iCloud account, where we cannot see them. The privacy policy spells out every detail, including the limited beta-analytics exception and the information we receive if you join the waitlist or email us.

Is it really free? What is the catch?

It is free, with no ads, no subscription, and no in-app purchase. There is no catch and no upsell waiting at task fifty. It is a small app made by one person who wanted it to exist.

How do I delete everything?

Delete the app and its data goes with it on that device. To remove the copy held in your iCloud account, delete your tasks inside the app first, let that change sync, and then delete the app. Export a backup first if there is anything you might want later.

7. Fixing things

Work through these in order. Each one starts with the thing that is most often the cause.

Tasks are not syncing between devices

  1. Open Settings in Just One on both devices and read the sync line. It usually names the problem outright.
  2. If either says Sign in to sync across devices, that device is not signed into iCloud. Sign in through the system Settings app, then reopen Just One.
  3. Check both devices use the same Apple Account. Two accounts cannot see each other's data, by design.
  4. Open the app on both. Sync runs while Just One is open, so a device you have not opened in a week has not sent anything yet.
  5. If it says Offline changes saved, your edit is safe and waiting for a connection. Check the network and reopen the app.
  6. Still wrong after a few minutes: export a backup from the device that has the correct tasks, send it to the other device, and restore it with Merge. Nothing is lost either way.

"Sync paused — data too large"

iCloud gives each app a small, fixed amount of this kind of storage. A very long history can fill it. Your tasks are safe on the device — the app has simply stopped sending them. To free space:

  1. Export a backup first, so nothing you clear is gone for good.
  2. Open Completed and clear out old finished tasks.
  3. Delete tasks you know you will never do.
  4. Shorten unusually long descriptions.
  5. Reopen the app. The sync line should return to normal.

A reminder did not arrive

  1. Check Settings, then Notifications, then Enable notifications in Just One.
  2. Check the system Settings app, then Notifications, then Just One, and make sure Allow Notifications is on.
  3. Check whether a Focus mode, Do Not Disturb, or Scheduled Summary is holding it back.
  4. Remember what the daily reminder does: one nudge, only on days you have something waiting, at a varying time between 9am and 9pm, and skipped completely once you have finished a task that day.
  5. For a specific time, the task needs both a due date and a due time. A date alone does not schedule one.
  6. The app schedules up to 40 timed reminders at once. Past that, the furthest-out ones wait their turn.

A widget shows the wrong task, or will not update

  1. Open Just One once. Widgets read a snapshot the app publishes when it runs.
  2. Hold the widget, tap Edit Widget, and check it points at the right list.
  3. Give it a few minutes. iOS decides when a widget redraws, and it is not always immediate.
  4. If it is still stale, remove the widget and add it again.

The Apple Watch app says it is waiting

  1. Bring the iPhone near the watch, with Bluetooth or Wi-Fi on.
  2. Open Just One on the iPhone once, so it can publish a fresh snapshot.
  3. Check the Watch app on your iPhone and confirm Just One is installed on the watch.
  4. If you tapped Done or Skip while out of range, it is queued and will send itself when the two reconnect.
  5. Restart both devices if none of that helps.

A task has vanished

Almost always one of four things, in this order:

  1. The focus window. Due Today and Due This Week both hide tasks that have no due date. Set the window back to no filter in Settings.
  2. The wrong list. Check the list picker.
  3. It is finished. Check the Completed screen.
  4. It is disabled. Open Manage Tasks; disabled tasks stay in the list but never reach Focus.

If none of those explain it, restore your most recent backup with Merge and email me. A task disappearing is a bug worth hearing about.

8. Accessibility

Just One is built to be usable without sight, without fine motor control, and without motion.

  • VoiceOver — every screen is labelled, and Focus announces the new task after you finish or skip one.
  • Reduce Motion — turn it on in your device settings and the card transitions become plain, immediate changes.
  • Buttons instead of gestures — set Done & Skip to buttons only if swiping is difficult.
  • Dark and light — set per device, and every accent is checked for text contrast in both.
  • Haptics and sound — both can be turned off.

If something is hard to use with an assistive technology, tell me. That is a bug, and it goes to the front of the queue.

9. Reporting a bug

Email info@sambruneau.com. A report I can act on has five things in it:

  1. The device and its system version. For example, iPhone 15, iOS 26.2.
  2. The app version, from the bottom of the Settings screen.
  3. What you did, step by step.
  4. What you expected to happen.
  5. What happened instead. A screenshot or screen recording is worth a lot here.

Do not send a backup file unless I ask for one — it holds all of your task text, and I would rather not have it.

Feature requests

Send those to the same address. Some things are deliberate absences rather than missing features: Just One will not gain a list view on the Focus screen, productivity scores, goals, streak pressure, or badge counts. Everything else is worth asking about.

Talk to a person

There is no support queue and no ticket number. Emails go to Sam, who writes the app.
