## What is Amazing Slow Downer?

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.

### 1/5 — Isn’t working

*2026-08-11, version 7.0.0*

I subscribed and downloaded the app. It is not functioning properly in terms of setting up loops.

### 5/5 — Great app

*2026-06-19, version 7.0.0*

I have been using this for many years, long before iPhones became into being. When it ported to phones I jumped right in! I used to drive commercially and I play Irish music. So learning the intricacies of what some of the greats are doing is much easier slowed down. I also don’t really read music so memorizing first is great. Hours in the truck. They’re play in Eb and you want D? No problem. I highly recommend this app. 
The only problem I just noticed, a new instrument and a teacher sent me an m4a file which it won’t import 😢

### 5/5 — Amazing Slowdowner

*2026-06-04, version 7.0.0*

A wonderful piece of software.  Well described in its notes. Works very well. I use it for nearly all my tune learning. Thanks 👍

### 1/5 — No longer useful

*2026-06-02, version 7.0.0*

I used to be able to learn songs in different keys for artists that would change the key due to illness or stress. Now I can’t do that. First you dropped Spotify, and made us use Apple. I spent thousands of dollars buying songs in Apple over the years to be able to use this app and now Apple doesn’t work. But that’s ok. It’s a real shame this app is pretty much useless now.

### 5/5 — Good, but no Spotify?

*2026-06-01, version 7.0.0*

it has Apple Music integrated, can we please get Spotify as well? I’m sure years ago it had this unless I’m having a fever dream. Please, include Spotify integration!

### 5/5 — Absolutely Amazing

*2026-06-01, version 7.0.0*

Absolutely the best I’ve used. The preservation of sound quality, even at the extremes of the playback speeds, surpasses expensive software like Logic Pro. Well done!!! 🤗

### 5/5 — Props to the developer/s

*2026-05-20, version 7.0.0*

Props to the developers of this app. They clearly know what they’re doing. The wifi import feature is fantastic. Glad to see this app continuing to get updates even in apples tyrannical ecosystem <3

### 5/5 — Super App

*2026-04-29*

Super App, benutze ich seit Jahren! Ich bin Musiker und arrangiere oft Stücke - die App ist für mich ein Must-have. Beim Tempo Änderungen bleibt die Audioqualität hervorragend. Es gibt zahlreiche Einstellungsmöglichkeiten wie Startpunkt, Endpunkt, Loop und so weiter. Das Design ist zwar etwas veraltet, aber die App erfüllt zuverlässig ihren Zweck. Für macOS würde ich mir wünschen, dass das Fenster skalierbar ist und sich verkleinern lässt bei der Arbeit parallel mit einem Notationsprogramm ist der Platz oft sehr wichtig😊

### 5/5 — Great product

*2026-04-20, version 7.0.0*

Great app for learning guitar, and outstanding customer service!

### 5/5 — Help with loops on iPhone - automatic skip

*2026-04-16, version 7.0.0*

This app is amazing ! Thank you for marking it. Can you please mar an update to automatically go to the next loop for iPhone . I want to use this in the car and I want ti be hands free
