Way too simple for the price it asks
This app is nice and easy, it shows a dot on the screen that is red when you’re not loud enough and green when it’s good. However that’s literally it! You need to set the decibel level yourself and there is no guidance on how to chose that level. I expected the app to at least provide indicative decibel levels for specific situations (e.g. meeting, speech, quiet room, etc.) and advice on how to train and improve your voice. I hope updates will be made on this otherwise the app is not worth the money.
