Reminder app gives no alarm

If you are expecting the Reminders app to create a separate alarm in the Clock app, that is not how reminder alarms are designed to work.

In iOS 26.2, Apple introduced the ability to mark a reminder as Urgent. When an urgent reminder has a due date and time, Reminders schedules an alarm for that reminder. This alarm is handled by the Reminders app and does not appear as a separate alarm in the Clock app.

Importantly, an urgent-reminder alarm can sound even when your iPhone is silenced or when a Focus mode is active. It is therefore different from an ordinary reminder notification.

How to set an Urgent reminder

1. In a Reminders list, tap the reminder you want to mark as urgent.
2. Tap the Info (ⓘ) button.
3. Under Date & Time, turn Urgent on.
4. If a date and time have not already been set, they will default to the next hour.

To mark reminders as urgent, you need to set up iCloud Reminders.

Once enabled, the alarm remains associated with that particular reminder. You should therefore not expect to find it under Clock → Alarms.

An important limitation

Alarms for urgent reminders will only activate on the device that Find My uses as your location. This matters if you have multiple Apple devices signed in to the same Apple Account.

So, if you do not receive the urgent-reminder alarm on the device you expected, check which device Find My is using as your location. The alarm is tied to that device rather than being independently created across all your devices.

In short: Clock alarms belong to the Clock app; urgent-reminder alarms belong to Reminders. The latter can behave like an alarm—including sounding through Silent mode or Focus—but they remain an inherent part of the reminder rather than appearing in the Clock app.
