### 5/5 — Great app and musch cheaper than Amazing Slow Downer

*2022-04-11, version 1.0.1*

I bought this app as an alternative to the $49.99 Amazing Slow Downer App for desktop. The interface is simple and works great. Easy to load tracks. If you don't need all the bells and whistles but just want to be able to slow down your music to hear more clearly, this is the way to go. I am a classical pianist/teacher using this for piano lessons to hear ornamentation more clearly.
