### 1/5 — No sound

*2024-07-14*

Not sure what’s going on I downloaded this app and I could not get any sound out of it I tested other apps I have and I got sound just fine so for some reason no sound!

### 2/5 — Needs update

*2023-01-07*

The tone seems to work okay but the app doesn’t keep the phone from a screen lock and then shuts off every time the screen locks. Please fix this.

**Developer response:** It's fixed now. The screen stays on in the newest version. Thanks for your feedback.
