SLS is an excellent tried and true method for all singing styles. This app is great for bridging the various breaks in different voices. Especially if ityou have a big vocal range with several breaks. However, you need to know what vowels to sing to the notes provided. A novice may not know and the app gives no guidance on this. Hence the 4 rating.

Thank you for your review. This is a companion for practicing the vowels/exercises you mentioned. I respect the creators of SLS, and teachers, and I think they are the best resources for learning these exercises - vowel consonant combinations - the right way.
