Settings

Open the lists panel and tap Settings to choose how 2Do looks, where new tasks go, and how it handles alerts, privacy, sync, and backups.

Sync

Open Sync setup to choose a service under Sync Method, sign in, and set automatic sync. Choose None to keep your tasks on this device without a sync service.

The available services include iCloud, Todoist, Dropbox, Toodledo, and CalDAV accounts such as iCloud CalDAV, Fruux, Yahoo!, FastMail, or a Custom CalDAV Server. Each service carries a different set of task details. See Sync Overview before choosing one.

Sync is a Pro feature, also available during the full-featured trial. Next sync action controls a one-time merge or replacement; the choices depend on the service.

important

A replacement action can overwrite tasks on this device or on the server. Create a backup first and check which copy you want to keep. Follow the recovery steps for your sync service.

Sharing

Open iCloud Shared Lists under Sharing to sign in and manage invitations and shared lists. Sharing uses its own iCloud account, so your regular task sync can use another service. It requires Pro or the full-featured trial. See iCloud List Sharing.

Default Collection List

The default collection list receives a new task when the current view is not a suitable destination, such as a Focus List. Tap the row under Default Collection List to change these options:

• GTD® Inbox creates an Inbox and makes it the default collection list. While it is on, the default-list picker is disabled.
• Default list chooses a particular list, or Last used to follow the list you last used.
• Always use default list sends new top-level tasks to the default even when another list is open.
• Always use in Quick Add makes Quick Add use the default regardless of the list you are viewing.

Creating a subtask inside an open project still adds it to that project.

important

Turning off GTD® Inbox asks to delete the Inbox and its tasks. Move any tasks you want to keep to another list before confirming.

Natural Language Input

With Quick Add or Task Editor on, 2Do reads dates and other details from a new task title and fills in the matching fields. Turn either switch off to keep titles exactly as typed in that part of the app. Both switches start on.

This section appears only for languages supported by the parser. See Natural Language Input.

Language

Tap the language shown under Language, then choose the language you want. After changing it, tap Quit and reopen 2Do to finish applying the change.

Appearance

The Appearance section controls the theme and the information shown in task rows.

Themes

Choose a color theme for 2Do, with a separate choice for your device's Light and Dark appearances. The available themes are Light, Dark, Ocean, Dusk, Azure, Midnight, and Ember.

1. Open Settings > App Appearance.
2. Tap the sun button to choose the theme used when your device has a Light appearance.
3. Swipe the row of theme previews to browse the colors, then tap a preview. A checkmark shows the selected theme.
4. Tap the moon button and choose the theme used when your device has a Dark appearance.

The sun and moon buttons choose which setting you are editing. They do not change your device's appearance. 2Do uses the theme assigned to the current device appearance and switches when Android changes between Light and Dark.

For a light app during the day and a dark app at night, choose Light under the sun and Dark under the moon, then use Android's display settings to schedule Dark appearance. To keep one theme all the time, select the same theme under both buttons.

Task Rows

Open Display mode to choose how much detail each task shows:

Mode	What you see
Compressed	Single-line titles and no note preview, with the list color shown as a band.
Normal	Titles can use two lines, with a note preview and indicators for details such as tags and alerts.
Extended	More room for long titles, tags, and notes.

You can also pinch the task list with two fingers to change display mode.

Grouped dates puts date-sorted tasks under headings such as Today and Tomorrow. Show overdue in red colors overdue tasks so they are easier to find.

Calendar Events shows appointments above your tasks. It is a Pro feature with its own display, calendar-access, and busy-day choices. See Calendar Events.

Appearance > More

Tap More... under Appearance for the remaining options:

• Friendly dates uses wording such as "Overdue by 3 days" in place of a calendar date.
• Show durations in headings shows total unfinished task time beside headings such as Today and Tomorrow. It is on by default in 2Do 3.2 and later. See Duration Totals for how projects, filters, and sorting affect the total.
• Markdown editing enables Markdown while editing and displaying notes. Markdown in note previews controls Markdown in the previews beneath task titles.
• Under Today, choose Include overdue tasks, Include starred tasks, and Always show 'Still Working On'. The last option keeps tasks with past start dates visible; turn it off to hide them unless they are due today.
• Under Sorting, Starred above Hi-Priority puts starred tasks before high-priority tasks. Grouped dates is the same option shown on the main Settings screen.
• Under Search, Project view inherits search keywords keeps a search applied when you open a project. Turn Show sub-tasks separately off to hide matching subtasks when their parent is already in the results.
• Show Completed Tasks chooses how long completed tasks remain visible. Apply inside of a Project view extends that rule to subtasks in an open project.
• Auto-Delete Completed Tasks chooses when completed tasks are deleted. Delay deleting sub-tasks by 3 weeks gives completed subtasks extra time before deletion.

note

Include starred tasks can bring starred tasks into Today even from lists excluded from Today. Counts based on Today can change with this setting.

Auto-deletion removes tasks rather than just hiding them, and the deletions can sync. Keep it on Never if you want to retain completed tasks.

Privacy

Privacy separates access protection from list visibility:

• Password protect lists sets a passcode and chooses what it protects.
• Hidden lists changes which lists appear in the lists panel. Hiding a list does not password-protect it.
• Archived lists manages archived lists. Archived tasks stay out of most views, but can still appear in Smart Lists and Done.

Password Protect Lists

Open Password protect lists and turn on Passcode to create a four-digit code. Use Protected lists to select individual lists or turn on Lock everything for the whole app.

Widgets & Notifications controls whether protected content is allowed outside the app. Require password chooses when protection takes effect after leaving 2Do: immediately, or after 1, 3, 5, or 10 minutes.

See Password Protection for unlocking, changing the passcode, and privacy limits.

Notifications

The main Notifications section offers Sticky alert, Alert sound, and Proximity alerts. Sticky alert keeps Today visible in Android's notification area. Alert sound chooses the default sound for audible task alerts.

Task alerts need Android notification permission. Location alerts also need the location access described below.

Notifications > More

Tap More... under Notifications for these controls:

• Sticky alert and Hide from lockscreen control the ongoing Today notification.
• Exact alerts opts in to more exact alarm scheduling. Exact alarm access shows whether Android allows it and opens the system access screen when tapped.
• Ignore battery optimizations opens the available system battery screen. If alerts or sync are delayed, check whether Android has put 2Do to sleep or restricted its background activity.
• Alert sound, Vibrate, LED Light, and Override Do Not Disturb control alert behavior where the device and Android settings allow it.
• Nag me repeats an alert at your chosen interval, up to five times.
• App Badge chooses the task count used by supported launchers. It requires Sticky alert to be on.
• Under List Counters, choose whether the lists panel shows no counts, overdue counts, or overdue and unfinished counts. Undone counts include overdue includes overdue tasks in the unfinished total. Include Smart Lists counts Smart Lists too.
• Snooze Alerts chooses the delay used by a notification's Snooze button.
• Auto-Reminders For configures Due Time and Due Date automatic alerts separately.

Android controls notification channels, exact-alarm access, and background limits separately. See Notifications and Alarms for setup and help with delayed alerts.

Proximity Alerts

Open Proximity alerts to turn on Enable proximity alerts, read the location-use notice, and grant the required location permissions. Location reminders need precise location and, on supported Android versions, permission to use location in the background.

Add locations to tasks in the editor. See Nearby and Locations for the task setup and Android permission steps.

Advanced

The Advanced section contains export, backup, and Advanced settings.

Export as CSV

Open Export as CSV, choose the lists and task selection you want, then use Export to share the file. CSV makes task data readable in a spreadsheet or another app. Use a backup when you need a file that 2Do can restore.

Manage Backups

Open Manage Backups to create, restore, share, or delete backups. Backups are a Pro feature, also available during the full-featured trial.

Automatic backups offers Never, Every 24 hours, or Every 48 hours. Keep at most sets the retained count. Backup before performing Sync adds a copy before sync.

Backups use App storage (default) unless you choose a custom folder. Save a copy outside the app before removing 2Do or changing devices. See Backups for the exact steps and restore warning.

Advanced Settings

Open Advanced settings for these options:

• Week Starts chooses the first weekday in calendars and date pickers.
• Work Week chooses your working days. See Work Week below.
• Default Due Date sets a date for new tasks and lets you choose whether Quick Add uses it.
• Default Due Time and Default Start Time set default times and the time shortcuts shown in the task editor.
• Due time can overdue decides whether a timed task becomes overdue at its due time or after the day ends.
• Checkmark Sounds plays a sound when completing tasks.
• Email diagnostic report prepares logs to share with support after you confirm. Automatically send logs with crashes controls automatic crash-log sharing.
• Reset all data removes local app data and starts fresh.

See Dates and Durations for date and time behavior.

warning

Before using Reset all data, create a backup and save a copy outside 2Do. Check that any tasks you plan to recover through sync are already on the server.

Work Week

Work Week requires 2Do 3.1 or later.

Choose the days you work under Settings > Advanced settings > Work Week, beside Week Starts. Tap a weekday to include it or leave it out. For example, select Sunday through Thursday if Friday and Saturday are your days off.

2Do starts with your device's regional work week. Keep at least one day selected; you can also select all seven. Tap Reset to return to the regional defaults. Changing Week Starts reorders these controls and keeps the same work days selected.

Date pickers and the mini calendar shade days outside your work week and dim their weekday headings. You can still choose those dates for tasks or date filters. Changing the work week does not move task dates.

The Work Days repeat shortcut uses this selection when you apply it to a task. Work Week is available in the free app, and you choose it separately on each Android device.
