Amazing Slow Downer Reviews


Great but overpriced  bodhisattva87  4 star

Great app. If I'm transcribing a song or want to practice a specific section, I like that I can make a short piece of the song loop. I'm not happy with how much I paid for it though. I didn't look terribly hard but I was surprised that I couldn't find a cheaper alternative.


A godsend  MedaThug  5 star

I've been using this app for years, and it remains my favorite app in music. It makes life so much easier as a piano player figuring out the lines of my favorite pianists.


ASD  Larpup  5 star

Been using for years. Sound quality is excellent. Ez and a tremendous aid. Highly recommend it. Updated 10/22/2027-still the best!!

Poke-mon :)

Not worth $15  Poke-mon :)  3 star

It's good other than when you use the sliders, usually you can't change it by small amounts. It skips whole semitones so you can't really change it by less than two semitones reliably.


Music AND Language! At the same time!  TheMrHartman  5 star

I have had this app for years. At first didn’t use it much but then moved to China where I slowed down transcripts so I could copy the pronunciation (along with the tones). I am now using it to slow down songs so I can learn the rap portion in Chinese as well as instrumentals! Well worth the money I bought it for. I have dropped pitch of songs too. Does a good job of changing key without too much distortion.


Needs a redesign  Antkn33  2 star

I like the ability to access Spotify. However the interface leaves a lot to be desired. It is very difficult to start at a precise spot in a song and even more difficult to loop a portion with precision. Capo and Anytune show you a waveform of the music sonic they are much easier. But they do t have Spotify.


UPDATE  jjplaysguitar  5 star

App not working with IOS 11

Great fun for audio experimentation  A. Designer  4 star

Would be really nice to have audiobus capability. This app can be used in a performance setting using pre-treated audio recordings - and it would be great to be able to run it into AUM or other iOS based mixing platforms.


Trumpeter transcriber from solos to horn parts  popeye4ever  4 star

This is an awesome app, everything I needed and more. Cutting my transcription time 3 fold. I would have rated it 5 stars only for the problem Apple created with its MP4 proprietary crap not allowing music you've purchased through them being used with ASD. I hold Apple/iTunes the blame for this. I paid for the use of the music I should be able to use it as I please. I've sent the request as ASD suggested to Apple requesting they allow ASD access to iTunes purchased music!


Just a piano guy  pianoguy2102  5 star

Great app for pro musician. What would be cool would be to add a keyboard to the app so that you can play along within the app. As it is, I have to always be on an external instrument while I'm transcribing.


You need this App!  Eliza_Doolittle  5 star

It’s must have! Perfect App so many ways. Have got so much use from it. Really helpful learning songs. Buy it!


Where is the Dropbox button???  Tania_tjc  2 star

I love this app. But with recent upgrades the Dropbox button has gone missing! Please bring it back! I NEED IT!!!


So useful. So easy to use  Paediatrician  5 star

I have been using for past 3 years. ALWAYS use when I practice (and apart from improving my rhythm and tone, having the tune play in the background makes me sound even better! )thankyou.


Good but Spotify doesn't work  Lucas.L.M.  2 star

The app itself is pretty good. One can change the velocity of a song, change the pitch and even loop certain parts of a song. But the reason why I paid more than 20$ for this app is because of the Spotify function. AND IT DOESNT WORK! Every time when I try to connect ASD with Spotify, the same error notification pops up:" Cannot connect to the Spotify server" This really annoys me because that was the main reason why I bought it. Really disappointing.


Excellent  Mike.p.  5 star

Straightforward, simple but does everything you need, create and store loops etc as well as the usual speed and pitch. Mainly I like how big and easy the buttons are, when you have an instrument in your hands it's easy to quickly tap pause/play and quick rewind (which you can set to go back in different increments - great feature). Hopefully they don't change this aspect. You can't see the waveforms of the track but I don't think that is a problem, if anything it probably helps keep less cluttered.


Great App  Timkeys  5 star

Nice update Moving songs works well


Amazing Slow Downer  hoola100  5 star

This app is a must have for any serious musician. It continues to improve with each version. Quality of audio is good even at slowest rate. Looping functions well. Computer version is also handy.


Amazing  Tvfairy  5 star

The best app on the store. Works perfectly Constantly updated No glitches and works just brilliantly. Buy it. You won't regret it, Fantastic customer service.


Awesome  Pepsicle84  5 star

This has got to be one of the only apps that stays on my phone constantly. Does what I need when I want it to. It comes in so useful when I'm trying to figure out parts of music and I love its ability to transpose the track.


Fantastic  vonderbah  5 star

I was a bit hesitant because of the price, but it was exactly what I was looking for, and so easy to use. If you are a musician striving to better yourself this app is for you.


Great but hope it works with apple music  KH12474  2 star

It works well with spotify. But since apple music has a lot more music than spotify, I really hope the app supports apple music..


No iTunes  saxguyvi  1 star

Wish I had known that iTunes wasn't supported before buying It works on my of so figured it would work here My bad Don't make the same mistake I did


Love it  monodalia  4 star

Perfect for transcriptions and learning fast lyrics. Also I like supporting independent developers.


Simply invaluable  kedeleon58  5 star

The addition of Spotify integration has mad this app worth every penny. As a drummer there's no better way of learning a song than by slowing it down and this app makes that 1 million times easier.

Jdkdndi kennels

Need one change  Jdkdndi kennels  4 star

I use this app a lot I mix and slow the music . One thing you should do is when we are done making our song let us put it in our music my library on my apple phone. Everyone that uses this app of my friends agree. Please consider!!!!!


Truly amazing!  indieninja  5 star

I am a student of Middle eastern music, and I got this app to help me learn repertoire for the Oud. It is wonderful, intuitive, and works amazingly well. It seamlessly integrates with Spotify where all of my Oud playlists are. It is wonderful to have independent control of both speed and pitch. There are two major types of Oud- Arabic and Turkish. They are tuned differently, which makes it very challenging to learn by ear if like me you're playing an Arabic Oud but trying to learn Turkish pieces. With the pitch control of this app, this problem disappears! Add to this the fact that you can slow down difficult passages without distortion and it opens the door wide for learning in minutest detail. I could not be more pleased and impressed. Find a way to do this with YouTube videos and you'll be unstoppable! Thanks for a great product!

Very impressed!  Santo Valera  5 star

I work as a singer and I'm constantly learning new songs for gigs. This app has helped me so much. Thanks!


Could be great, but it isn't.  Yhnkf  1 star

I love the interface and the actual functionality of slowing down tunes with this app. The only problem is that it doesn't work with Apple Music, which nowadays is how I get my music. If you have a Spotify Premium account you'll be happy. Otherwise it's not worth it.

G's dad

Absolute Waste!!!  G's dad  1 star

$14 for an app that doesn't play any songs from my iTunes and wants you to have a premium Spotify account? Total rip off!


Love this app  212nyny  5 star

I'm a classical pianist and love using this app to examine at slowed down tempos what the professionals are doing. This app is so helpful! Thanks!
