### 5/5 — To the point!

*2026-01-29*

Its great. Just wish you could randomize the whistles.

### 1/5 — Useless! Doesn’t run in background.

*2022-10-31*

This app only runs when your phone is on and you are in the app. It would be good for a broader range of uses if you didn’t have to be in the app. Right now this is useless for me.

### 3/5 — Almost…

*2022-06-14*

Someone else suggested the ability to add more lines for different timings of reps, sets, and breaks and such. That would be great! The issue I have is that the shortest possible interval is 5 seconds. Was looking to set up whistle drills for Lacrosse Face-off drills where it uses two or three whistles a second or less apart to break down the move followed by a delay before the next rep. Sadly this is not a feature of the FOA app.

**Developer response:** Thank you so much for the review! I'm working on a new update and will make sure it's more flexible.

### 1/5 — I see that the devs actually look at reviews

*2021-09-20*

Hello! Your app would be a 5/5 if it just gave the option to add more lines… it allows you to put breaks between groups of reps in a set but not between sets. I want to be able to do 5 sets of 45 seconds with ten second breaks and then a 1 minute break before those five sets and breaks repeat! That would make your app perfect for anyone doing HIIT workouts!

**Developer response:** Hello,

Thanks so much for the review! I really love this idea! Would love to hear from you at apps@oval.fi and chat the details so I can make this happen.

### 1/5 — Don’t waste your time or money

*2020-05-13*

There is no sound for this app. If I could give it zero stars I would.

**Developer response:** Hi Taken50,

Thank you for the review!

Sorry to hear about the issue you had! The app definitely has sounds so it might be that your volume was set to very low?

### 4/5 — Faltan funciones

*2019-02-03*

La app se detiene si el teléfono bloquea la pantalla y no se escucha el silbato.

### 1/5 — Doesn’t work with screen off

*2018-10-29*

Needs. Setting to run in the back ground or keep the screen on while running

**Developer response:** Hi Piaamp and thanks for the review!

The latest version keeps the screen on while running.
