About this app
As a parent raising a child, I made an application called ‘Don't cry my baby’, to help other parents.
- It has mainly five (5) features.
Firstly, it is white-noise. For those babies under 3 months old, they easily fall asleep while listening to mother’s heartbeat, water drops, cloth brushing sound, etc. So, it is equipped with a function to play up to maximum three (3) sounds (you can select from twelve (12) sounds of white-noise, that are similar to the environment inside mother, such as TV noise, cleaner sound, heart-beat, vinyl bag, etc.) at the same time. (For your information, turning on music mixed with TV sound, water droplet, and heart-beat worked great on my baby)
Secondly, it is lullaby. This app is equipped with most well-known twelve (12) lullabies (English songs, classic, Music Box, etc.).…

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
65–79% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.

Developer says data deletion can be requested
The developer's data-safety disclosure on the store states that users can request deletion of their data, or the app's own text offers a way to delete the account. This restates what the developer declares; it is not a test of whether deletion works. Apple publishes no equivalent disclosure, so on an Apple-only listing only the app's own text can support it.
What we saw: The developer's store data-safety disclosure states that data deletion can be requested; we have not seen a deletion control in the app's own text
