### 1/5 — It doesn’t work

*2025-08-28*

Volume goes all the way up and doesn’t work. There’s no way to fix it

### 1/5 — Not worth the time

*2020-07-11*

There are better options that don’t limit your time and make you watch ads. They should just make this a paid app if they’re going to do that.

### 1/5 — 1 minute use time?

*2020-06-26*

Just make it a paid app.  Jesus.
