Notifications that let you sleep: how quiet hours work
Philos only makes a sound when one of your people talks to you. Here's what notifies you, what never does, and how quiet hours hold messages until morning.
In short
- Only people talking to you, or answering you, make a sound. Posts and Moments never notify you, unless someone tags you.
- Quiet hours start on, from 22:00 to 07:00. Messages wait for one gentle note when they end.
- Let a Circle, like Close friends, through quiet hours, so the people who matter can always reach you.
In 2019, a team of researchers did something few of us dare to: they changed when 237 people’s phone notifications arrived. Some got them as usual. Some got none at all. Some got them bundled, three times a day.
The people who got them three times a day felt more attentive, less stressed and more in control of their phones. The people who got none weren’t calmer: they felt more anxious about what they were missing.
That’s the balance we aimed for on Philos. Not silence. Just fewer, kinder interruptions, from the right people.
What makes a sound, and what never does
Philos tells you about people, never about the app. On the sheet that asks to turn notifications on, we put it plainly: no streaks, no suggestions, no reminders to scroll.
If one chat sends several messages in a row, you hear one sound, and the rest arrive quietly beneath it.
Quiet hours: on from the start
Quiet hours start on, from 22:00 to 07:00. During them, nothing makes a sound. Messages wait, and when quiet hours end you get one gentle note, titled While you were resting, with what came in.
Requests, like someone adding you back or tagging you, still land in your notification list overnight, silently.
To change the times:
- Go to You, then Settings, then Notifications.
- Under Quiet hours, set From and Until, or turn them off.
Let the right people through
Some people should always be able to reach you: a partner on a night shift, a parent who’s unwell, a sister due any day.
- In Settings, then Notifications, tap Let Circles through.
- Choose a Circle, such as Close friends or Family.
Messages from the people in that Circle arrive right away, even overnight. Nobody is told who’s on the list. If you don’t have a Circle yet, make one first.
Mute a chat without a fuss
Hold a chat in your list and mute it. Messages still arrive, just without sound or notifications, and no one is told.
Questions people ask
Will Philos notify me when a friend posts?
No. Posts and Moments wait in your Feed until you open the app. The only exception is when someone tags you in a post.
What happens to messages during quiet hours?
Nothing makes a sound. Messages wait, and when quiet hours end you get one gentle note with what arrived, unless they're from a Circle you let through.
Can I still be reached in an emergency at night?
Yes, if you let a Circle through quiet hours. Messages from people in that Circle arrive right away, even overnight.
