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 audio from both "Apple Music" and "Spotify Premium"!

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.

Version 6.5.2

The best app for Lali

I’ve been using this app for 15 yrs from when it was first developed for Mac OS pre iPhone days. That should say it all! Best algorithms and plenty of tweaks. I’ve made some killer loops and thanks to ASD even Lali can agree that yes it’s a high tom and not a snare.🤪 Thanks Ronimusic, you rock

I recommend, I use the app simply just to calm the rhythm of my music when I’m relaxing. The only problem is we cannot use our Applemusic membership song.
