Google Tasks can send notifications when a task is due, but which app delivers the alert depends on your device. On Android, notifications can come from the Google app, Google Tasks, or Google Calendar. On iPhone and iPad, Tasks or Calendar can notify you. On a computer, task notifications are handled through Google Calendar. If you want a separate email reminder for a specific task, TaskAlarm adds that option without replacing Google Tasks.
Google Tasks does support due-date notifications. The confusing part is that Google can deliver them through different apps depending on the device you use.
On Android, Google says task notifications can come from the Google app, Google Tasks, or Google Calendar. If more than one of those apps is installed, only one may send the notification. On iPhone and iPad, Google Tasks or Google Calendar can deliver the alert. On a computer, Google directs users to enable notifications in Google Calendar and make sure Tasks is selected under My calendars.
That is why two people can use the same Google Tasks account and see different notification behavior on different devices.
Android: The Tasks app can deliver task notifications directly. In Google Tasks, open Settings > Notifications and make sure All Tasks notifications are enabled. Google also recommends allowing Tasks under Android's Alarms & Reminders permission if alerts are delayed or missing.
iPhone and iPad: Task notifications can come from either Google Tasks or Google Calendar. If both apps are installed, only one may notify you. iPhone Focus modes can also suppress alerts unless Tasks is allowed and Time Sensitive Notifications are enabled.
Desktop: Google Tasks notifications are handled through Google Calendar. Calendar notifications must be enabled, and Tasks should be selected under My calendars.
If your alerts are currently missing, see our dedicated guide: Google Tasks notifications not working? 6 fixes to try.
If you give a task a date and a specific time, Google says the notification is sent at that scheduled date and time.
Tasks that have a date but no specific time behave differently. Google's current Tasks documentation says those notifications can appear at 9 AM. Tasks with a deadline can also generate a 9 AM notification on the deadline date.
That difference matters. If you expected a task to remind you in the afternoon but only gave it a date, the notification may have already appeared at 9 AM.
Start by confirming the task has the correct date and time. Then check notification permission for whichever Google app is delivering your task alerts.
On Android, also check the Tasks app's Alarms & Reminders permission. On iPhone and iPad, check Focus and Time Sensitive Notification settings. On desktop, make sure Google Calendar notifications are enabled and the Tasks calendar is selected.
Because only one Google app may deliver a task alert on mobile, do not assume something is broken simply because Calendar stayed silent while the Tasks app notified you, or vice versa.
Google's native Tasks notification settings focus on app and Calendar notifications rather than a per-task email reminder that you schedule for an individual task.
TaskAlarm adds that separate email channel. It works with your existing Google Tasks from the Gmail sidebar. Choose a task, pick the reminder time, and TaskAlarm sends the reminder to your inbox.
The idea is not to replace Google's normal notification. You can keep the native task alert and add an email reminder for the tasks you especially do not want to overlook.
Keep Google's native notifications and add an inbox reminder for the tasks you really do not want to miss.
Get TaskAlarmYes. Google Tasks supports notifications for scheduled tasks. Depending on your device, the alert may come from Google Tasks, Google Calendar, or the Google app.
Google says tasks with a date but no specific time can generate their notification at 9 AM. Set a specific time if you want the native notification later in the day.
Yes. On iPhone and iPad, notifications can come from Google Tasks or Google Calendar. Focus settings can suppress them, so allow Tasks and Time Sensitive Notifications if alerts are being missed.
On desktop, Google handles task notifications through Google Calendar. Turn on Calendar notifications and make sure Tasks is selected under My calendars.
Google's standard Tasks notification settings do not provide a per-task due-time email reminder. TaskAlarm adds a separate email reminder that you can set for individual Google Tasks.
