If you're a musician who likes to learn new songs and techniques by listening to the same piece of music over and over but wish that the music could be played a little slower, then you'll enjoy Amazing Slow Downer.

Amazing sound quality.

The App looks outdated

This might have been said before, but I'll say it again in case it was overlooked the first time. You all (Roni Music) have had major improvements over the years on the mobile app for iPhone/iPad with more features and a fresh new look. However, you seem to have forgotten about the desktop application as well. Not complaining about how it works (because it still does), but I feel like I'm taking more steps on the desktop app to do what I can effeciently do on the mobile app with a few clicks. I would like to have it where all my apps are the same or similar in look, features, navigation and even sync up via iCloud. I feel this is a reasonable request all things considered.

Still the best

I have used this application for years, and it's still the best for the obvious functions that it provides. It can also export files from saved settings which is incredibly useful. Unlike the rather limited iOS version, you can save numerous loops of music per track, each with its own unique pitch, speed, and start and stop points. The interface is straightforwardly functional. It's very easy to add music to this app as well - just drag the file into the app window. I can see that ASD has countless clones now, but none of them seem to quite nail the functionality of this classic gem.

Terrible help manual
