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 Lite.

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 Lite handles that as well.

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

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

Supports playback of streaming "Apple Music" audio!

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

Important notes:
This free "Lite" version is restricted to play the first quarter of an audio file.

Over-priced simple app

$21 for something I can do with plenty of free software? Who is actually paying that price...?

Developer Response ,

People that want very good audio quality, support for Spotify and "Apple Music playback and a lot lot more. Plus an app that never crashes.

Excellent music app

I’m an amateur guitarist who like to play solo guitar. I can use the app to shorten the music piece and slow it down. Then play it over & over by using its repeated feature while I’m learning how to play. Even I turned off my iPhone, it’ll still play the music. Very convenient. I love it!

Import issue

Why is that when I import a music file I can only see half of the file when I’m playing the audio.??????

Developer Response ,

That's an intentional limitation in the free lite version.
The regular paid version doesn't have any such limitations.
