If your baby always keeps crying, please try this app and let your baby listen to the sound on the app.
The sound can effectively calm your baby down.
If you cannot stop your baby from crying after using the app for a few minutes, please stop using the app and check if your baby is sick, hungry, or it is due to other reasons.
For the sake of your baby's health, please turn your phone to the flight mode when you use the app close to your baby.
