Focus blocks calendar alerts. Alarms, allowed callers and Emergency Alerts still get through. For a meeting, only the alarm is a usable option.
Focus is doing what you asked. The confusion is that people set up Focus to protect their attention and assume their calendar counts as important enough to be exempt. It does not, and there is no toggle that makes a calendar alert behave like an alarm. The fuller explanation of why calendar reminders do not wake you covers why the two are different classes of event.
What does Focus actually filter?
Focus works on notifications. You choose which people and which apps are allowed to notify you, and everything else is held back or hidden entirely. A calendar alert is an app notification, so unless you explicitly allow the calendar app and enable time-sensitive delivery, it will not appear. There is a fuller walkthrough in different lead times per calendar.
Even when allowed, it is still a notification: one sound, one second on screen, and it obeys Silent Mode independently. The difference between the two categories is laid out in a real alarm compared with a calendar reminder.
What gets through a Focus anyway?
Three categories, regardless of which Focus is active.
- Alarms and timers. Exempt by design. The one thing you can schedule for a meeting.
- Allowed calls and apps. Only the people and apps you added to that Focus.
- Emergency Alerts. Government-issued and not something you can use.
Does Time Sensitive fix it?
Partly, and unreliably. Marking a calendar app as Time Sensitive lets some of its notifications break through a Focus, but it does not change the category: Silent Mode still mutes the sound, the banner still disappears, and whether a specific alert qualifies is decided by the app rather than by you.
| Type | Appears | Makes a sound |
|---|---|---|
| Calendar alert | No | No |
| Time Sensitive alert | Sometimes | No |
| Alarm | Yes | Yes |
How do you use this deliberately?
Keep Focus strict. Do not start punching holes in it for calendar apps, because the holes are what made notifications useless in the first place. Instead, let the one category that Focus respects do the job: an alarm, before each meeting, from every calendar you connected. That is the difference between reading a missed banner at nine and sleeping through a morning meeting. That is what Pealo does on iPhone, using the system alarm framework rather than a notification.
Keep Focus on. Hear the meeting anyway.
Pealo schedules real alarms, which no Focus mode blocks.
