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.

You can repeat any section of the music at full speed, slow it down or even speed it up by changing the speed between 25% (1/4 of original speed) and 200% (double speed) without changing the pitch!

Change the tuning or musical key? No problem, Amazing Slow Downer handles that as well.

Setup seamless loops by touching the "Set" buttons during playback.

Amazing Slow Downer is the ideal tool for any musician, transcriber or dancer wanting to improve their skills.

Supports playback of streaming "Apple Music" audio!

Note: Some functions such as "Pitch change" and "Equalizer" are not available when playing "Apple Music" songs.
"Apple Music" requires iOS 10.3 or better.

What’s New

Version 6.6.7

New - Added a "Next Song" button in the player view.
Bug fix - Fixed a problem related to searching when using a BlueTooth keyboard.

I couldn’t be happier with this app.

I like to use city ambiance and rain sounds etc that I’ve bought from the iTunes Store to help me sleep. You can access these in app and loop them so that loop is seemless and doesn’t get interrupted when it restarts again. I’d like to say thank you to the developer.

Unfortunately when selecting a loop to slow down the app only allows you to divide a section in one second increments. This is irritating if you are playing the section on a loop either to listen or try and play along as the rhythm breaks after each loop. I would be happy with the app if it was cheaper but coming in at £15 I would expect something as simple as being able to cut the track into 1/10 second chunks (or even 1/100 second) to be covered

Still great!

Been using ASD on PC and Mac for years and now using this version on iPhone/iPad. Awesome piece of software which does exactly what it says altering tempo and pitch with ease and doing it well. iOS version is just as good as the computer version. Highly recommend.
