Constant request for more money
This app concept is great. However the free version is really not free. Use it for a couple of minutes and immediately its asking you to upgrade to add more time. Add more time and you get a few minutes and exercises more and then you have to refill again! The manufacturer needs to know that CONSTANT incremental pricing is annoying and not cost effective. I would rather be charged a fee for using the app than to be limited in this way.
That being said, the functionality of the app is excellent and very helpful to those trying to sing correctly.
Hopefully the creator will read this and change pricing strategies.
