### 5/5 — Hi

*2025-10-16*

Hi

### 1/5 — Might have malware

*2024-08-23*

When I opened this app on my phone, it prompted me to download an entirely different app. I never saw anything close to a decibel level or meter. I deleted the app immediately.

### 1/5 — No changes

*2024-03-05*

I have an annoying noise in my house that I was hoping this app would help me solve. However, the decibel readings are the same no matter when or where I use it.  There are  certain days and times when the noise is louder, yet the readings are always the same. So, I don’t think it works like it should.
