Nothing pops up at 3 a.m. Plays with the screen off and offline.
Timer and fade
Set 30 minutes to 3 hours, or until morning. The sound fades out gently.
How loud and how far from the crib?
Use the lowest volume that works, keep the phone or speaker at least 2 m (7 ft) from the crib and never inside it, and use the timer. A 2014 study found infant sound machines can go above 50 dBA at about 30 cm (summary by CHOP). Brezi is not a medical device; talk to your pediatrician if you have concerns.
Can I play while I use other apps?
Yes. Turn on "Play along with other apps" in Settings to keep the sound going while you watch or listen to something else.
Is Brezi made for children?
Brezi is an app for adults. Parents use it to play sounds while the baby sleeps; the child doesn't use the app.
