Does not work with new Apple iOS.  littlepigmusic  1 star

iTunes and the new apple iOS protects the music and even though I bought the music, I can only use iTunes to play it. Unfortunately the only way I found out was going to the developer website and reading the faqs


Marginal  Bradleybt  2 star

If your Apple Music was synced to the cloud and you try to play it the music won’t play because apple put some kind of encrypted tag on it. Good luck figuring out how to get music to work with this app.


Excellent  Bowser47  5 star

I use this app to help me learn Irish traditional music by ear. The only feature that I wish it had is the ability to download an mp3 directly from the web.

Still the Best!  Mikes jello  5 star

I first encountered Amazing Slow Downer when it was only a desk top app, and maybe the only of its kind, and the iPhone was still a dream. This app has every bit of that capability and then some. I highly recommend this for musicians.

What's Amazing about it is that it will not let me import any songs or created a playlist. Every song I try to use from ITunes gets blocked and says the song is "protected" and unable to import or add to a playlist

Helped my singing (Rhythm and pitch)  cutie Zalbu  5 star

A vocal teacher on YouTube called Rached,always recommends made the rhythm of my singing so much better and I’m currently slowing down songs so u don’t miss small details...sponsor that guys...he’s a great musician....thank you for the app developers...really helped my singing,if I put my music out there,I’ll definitely credit you guys for helping me in my singing journey


Weird problem  D'AngelicoExcel  5 star

I thoroughly rely on this program for school, and I paid for the license on iPhone, but for some reason it started only allowing me to hear three minutes of a song, as a week ago I could hear 6 minutes. Who do I contact about this and how do I resolve this problem?


Super high quality app that I can’t use much  XxDa_ManxX  5 star

This app was recommended to me by my guitar teacher and it’s really good and worth the price. But I have Apple Music. So only about 1% of the songs that I own can work on the app. This app is great but please get Apple Music to work with it. Thx

really great + request's  Zach T. O. C.  4 star

This app is wonderful and when it was shown to me and recommended to me by a friend I got it and was worth every penny. Within the first 20 minutes or so, was able to learn a phrase from a song I could never figure out for years. Especially good because i'm completely blind and rely on iOS' voice over and was happy to learn that the app was fully accessable to me. All in all a stupendous app and would highly recommend. Just a few requests. - add flick gestures for voice over users - a function to adjust the quantity a slider will change - The ability to change the name of imported files that are just a jumble of numbers and letters Thanks again for a great app :)

This app has been amazing for a year or so, but now and after updates it’s starting to glitch out all the time with error ‘playback failed’ ... very frustrating.

Patrick Sully

It really is amazing  Patrick Sully  5 star

As a singing teacher, I find this ap incredibly helpful! Changing keys, and tempo for learning and performing songs. Just brilliant.


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  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.


Great app!!  Poporopo00  5 star

I wish it had a fade in and out option when importing or sharing files but everything is great...awesome. (They block my e-mail address for asking to much but oh well...LOL)

Best app.!!!! Good job.


Fantastic for pitch and tempo shifting  Allquix  5 star

One of the best apps on the App Store for pitch and tempo shifting, definitely - the Spotify support is incredible!


Needs some restructuring  Theodare  3 star

First of all, the app does a great job at slowing songs down and maintaining pitch. My kids use this app to practice violin and they are able to slow down complicated pieces and hear the notes clearly. However, this app has several problems that need to be addressed to make it more user-friendly. 1)when you go to load songs from iTunes, for some reason it loads them in reverse order and you can't change them around once they're loaded short of deleting them. This means the first song you load becomes the last one on the list. Once you know this, you can begin at the bottom of the sing list and load them backwards, but this is silly and unnecessary. 2) ASD only lets you load one song at a time as opposed to loading an entire album. Not only that, it does not remember where you just pulled your last song from. This means for every song from an album, you have to find it again in iTunes as though it were the first time. Again, silly and unnecessary.


Used for years. First class app  adaptiveagile  5 star

Everything I need for music playback. Slowdown, pitch shifting, looping. Only drawback is it's primitive filing system which isn't that intuitive. I read that this update allows for media name edits which is a major step up.

Won’t Open  Kath Lin Ander  1 star

Bought and paid for, says it has been downloaded, won’t open. Now I can only find $50 option. Very Upset.

Nick of Namesu

Advanced control of your favorite songs  Nick of Namesu  4 star

Ever hear a song and wished you could slow it down without the pitch changing? Then this is the app for you! The Amazing Slow Downer (ASD) can do far more than just slow down songs. This application gives you the ability to manage your favorite music like never before. With the speed adjustment, pitch adjustment, and loop back features, you can hear your song the way you want to.


Waste of money  Sesrs  1 star

It won't allow you to access your voice memos. And needs a computer to import music


Awesome!  Visualride  5 star

These guys don't let this product sit idle, un-updated. I use it constantly.


Terrible Service. I Would not recommend.  Faynester  1 star

I purchased the full version of this product. Then purchased a new computer a little time after. I wanted to transfer the Amazing slow downer to my new computer but was told I would have to purchase the product again. Shocking.
