## What is Amazing Slow Downer Lite?

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.

New - Support for streaming "Apple Music" audio! 

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

Please note: According to Spotify, third party apps will not any longer have access to streaming Spotify content in a way that works for slowing down / pitch change audio starting September 1, 2022. This will affect Amazing Slow Downer.

This means that you should NOT buy Amazing Slow Downer if playing Spotify content is your only use of the app.
This change does NOT affect any other type of audio content that Amazing Slow Downer can play back.

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

### 2/5 — Works but kidnapped my original music

*2025-11-26*

It automatically kidnapped my original music I downloaded from my site.. then only gave a 30 second demo of each 😡

### 3/5 — Works OK.

*2025-11-05*

The very first thing I look for before downloading a new app is the app privacy. If it doesn’t show “Data Not Collected” then I’m much less likely to give it a serious look. Amazing Slow Downer passes the Data Privacy test so on that score it gets 10 out of 5.

I have other slow downer type apps as well but I’m looking to be able to recommend apps to my students. The difficulty I have with this app is that I don’t use Apple Music. I just do it the old fashioned way - buying individual songs. But I can’t seem to use Amazing Slow Downer with the selection of songs I have in iTunes. It seems limited to the online Apple Music and I find that puzzling.

### 3/5 — Spotify NOT supported

*2025-10-29*

Unfortunately Apple Music only supported

### 5/5 — Finger Picking

*2025-01-19, version 6.9.2*

Such a great tool for listening accurately.

### 1/5 — Terrible

*2024-12-08, version 6.9.1*

Does not work with Spotify. Spent half an hour trying to pull any song I have for Apple Music to slow down. Nothing worked. Terrible app

### 4/5 — Excellent app for transcribing.

*2024-12-06*

I have been using this app for years. I have the full version but it’s still the lite app with unlocked features. Overall an excellent app. It does exactly what you want it to do. Fine tune looping of sections of music, pitch shift and slow down feature, plus lots more. 

The one thing I find annoying is that there is no auto lock over ride feature. I have to disable auto lock every time so that I don’t have to keep unlocking my phone after a minute. If this can be fixed in an update, then it’s worth 5 stars.

**Developer response:** Look here:

Allow Sleep -> OFF

### 1/5 — Already paid

*2024-11-12, version 6.9.1*

Hello guys, I’ve already paid for the full version very long time ago but the icon remained as “ASD lite”. The app was functioning properly as a full version either in the iPhone and in the iPad. Then the iPhone cancelled it because I haven't used it for a long time, now I downloaded it back and it’s working as the lite version. Could you please help me? Thanks

### 1/5 — No Longer Works w/Spotify

*2024-09-23, version 6.8.9*

It used to be great, but it no longer updates or has compatibility with Spotify.

### 5/5 — Horrible app

*2024-08-19*

This is just in general terrible, I’m trying to memorize an audio and it doesn’t let me listen to the full thing. I put in a 12 second video and it only let me do 2 seconds worth, I gave this five stars so it would be seen, don’t waste your storage on this. And the version that costs money is just in general, way too expensive. I have had so many problems with this app, I tried to import a full minute audio and it only let me listen to the first 12 seconds. I have no idea how to fix this and the only way is most likely to buy the overly expensive app, I do not recommend, thanks for reading.

**Developer response:** As written on the App Store:
"This free lite version is restricted to play the first quarter of an audio file".
The paid version of course doesn't have this limitation.

### 1/5 — Why buy?

*2024-08-08, version 6.8.9*

So apparently you cant use this with spotify and I read a couple of comments saying it wont work properly with iTunes either. So whats the point of this app again? The description helps nothing
