The Voice trainer is originally developed for people with a poorly intelligible speech due to Parkinson's disease , but is also suitable for professional speakers and in consultation with a speech therapist for people with another voice or speech disorder.
With one dot on the screen, the app provides real time visual feedback on both loudness and pitch of the voice, allowing to see directly which aspect should be adjusted.
You can use the app to make it easier to independently practice your speaking technique, but also to check if you speak properly during conversation. Together with your speech therapist you determine the optimal loudness and pitch.

In Parkinson's disease or parkinsonism the app is used during speech therapy with the Pitch Limiting Voice Treatment ( PLVT ) , the Dutch method to effectively treat intelligibility problems in Parkinson's patients. The Voice trainer is therefore also called PLVT app.

For additional options, the ‘Voice trainer Supplement’ is available.

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.
