Alerts and Nag Me
A task is only useful if you remember to look at it. In the iOS editor, these reminders are called Alerts, and a task can have as many alerts as it needs.
Adding an Alert
Open a task, tap the Alarm icon in the bottom toolbar, then tap Create New Alert....
The New Alert screen lets you choose:

- Presets — quick choices such as On Time, 5 minutes before, 15 minutes before, 1 hour before, and 1 day before.
- Custom — pick an exact date and time, or turn on Relative to Due Date / Relative to Start Date when the task has a due or start date.
- Play Sound — turn the alert sound on or off.
- Save as Preset — save a custom relative alert time for reuse.
Tap Create when the alert is ready. Add another alert the same way if the task needs more than one reminder.

Presets and Custom Times
Presets are the fastest way to create alerts relative to the task's due time. They include common choices from On Time through minutes, hours, and days before the task is due.
Custom alert times can be fixed to a specific date and time, or relative to the task's due date or start date. Relative custom alerts can be before or after the task date, and can use any time of day.
Nag Me
Nag Me is a global notification setting, not a per-alert option. Set it in Settings > Notifications > Nag Me.
When enabled, every alert notification can keep reminding you until you view the task or mark it complete. Available intervals include every 5 minutes, 15 minutes, 30 minutes, hourly, or daily.
Automatic Alerts
Set automatic alerts in Settings > Notifications > Automatic Alerts. New tasks created with a due date or due time can inherit those reminders; you can still override per-task.
Overdue Notifications
Overdue tasks can alert you through 2Do's notification settings. Configure counters, nagging, and automatic reminders in Settings > Notifications. A white glowing dot also appears next to a list name on the Lists screen when something due today is hiding inside, and a red glowing dot appears when an overdue task is hiding inside.
Notification Permissions
For Alerts to fire, 2Do needs Notifications permission. If alerts do not appear, check:
- iOS Settings > Notifications > 2Do — turn alerts on, choose banner style, sound, and Lock Screen behavior.
- 2Do > Settings > Notifications — fine-tune 2Do-specific counters, Nag Me, and automatic reminders.
Snooze and Done from a Notification
When an Alert fires, the iOS notification offers actions:
- Snooze — remind you again later.
- Snooze 1 hour — remind you again in one hour.
- Due tomorrow — move the task's due date to tomorrow.
- Completed — mark the task complete.
Opening the notification itself shows the task in 2Do.
Tips
Stack a 15 minutes before and a 1 hour before Alert on important meetings. Early prep, late nudge.
Use Nag Me sparingly and meaningfully. Save it for tasks that genuinely must not slip — your filing deadline, the call you keep avoiding.
