Decide what cue you want
In a shared office, bedroom, or public setting, sound and vibration choices may matter more than the timer's appearance. Fastly lets you review those controls separately.
Check the relevant settings
Open Sound & haptics and inspect vibration feedback, goal chime, and milestone chime. Then check Reminders and device notification presentation for the actual alert behavior you want.
The controller cancels old goal and start schedules before computing the relevant new ones. Goal changes and start corrections resynchronize reminders from the current session data and current quiet-hour settings.
Understand the timing distinction
A quiet app theme does not imply silent notifications. Appearance, local reminder scheduling, and sound presentation are distinct preferences and should be checked on their own terms.
Keep control of the routine
Do not rely on a small icon alone to assume the device is silent. Review relevant system controls as well when quiet delivery is important to you.
