Highnote: Tempo and Key Control For Your Music

Highnote lets you adjust the tempo and key of the tracks in your music library as they are playing. It's an ideal practice tool for musicians and dancers. It’s also great for running or working out to your favourite songs at a speed that suits you.

And now, Highnote on Apple Watch makes it more convenient than ever to adjust the tempo and key of your music as it plays.

"While there are other apps on the iOS App Store that offer similar features, Open Planet Software's Highnote offers a simple, clear and beautiful-looking interface that allows you to focus on practicing, without any distractions." -

I use it for vocal exercises and music practice. I am able to change the tempo and pitch, I enjoy.. The only improvement i'd like to in the future is key change being greater than 6 octaves..

Can't save or email the track

why can't I email the track to myself after mixing my chosen track? especially for a $5 value.
