### 5/5 — Turn off silent mode for starting signal.

*2022-06-19*

I like this app, another reviewer mentioned that there was no sound, but you have to turn of silent mode(toggle side switch above volume buttons). The delay feature is nice for training on your own, it is in milliseconds though. Overall great app, me and my teammates use this.

### 3/5 — No sound

*2022-04-16*

I like the ease of this timer, however, I can’t get the official start signals to sound. Any suggestions?
