Amazing Slow Downer Reviews

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.


ASD  Flemanif  1 star

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 :)


NYC Violin teacher here, uses frequently  Gmail4eva  4 star

I am violin teacher and I use and recommend this app a great deal. However, there is one thing I would really love if the developers would consider (which would make this a 5-star review) and that is a way to adjust speed percentages by + or - 1 with the tap of a +-1 button just like you can with moving forward or backward in seconds. I would also love love love if you could either modify the small movements back & fwd or have more options available to do so (e.g. 5, 10, 15 seconds.) It would also be out of this world if you could develop place markers or tabs for points of difficulty that you could just jump to go practice. E.g. One at 1:36, one at 2:30, one at 14:53, etc. (Also would be great for jumping to the next movement in classical music). That being said I will continue to use this app and hammer on the << or >> 1 second button until this feature (hopefully) comes out. I haven't tried other similar apps (if they exist) but this one has been great to me, so am true blue all the way. Highly recommended. Get it.


More than worth the price!  JKL718  5 star

More than worth the price! Truly a game changer! I tried cheaper options and their interface looked more interesting, but those looks were deceiving. Those others were difficult to effectively manage and really buggy. ASD proved to be “amazingly” intuitive, easy to organize what you’re learning, and completely bug free. You do have to “own” your iTunes music that is imported, and they have to be downloaded to your device—Apple won’t let you work in other programs with their music otherwise. I do pay for Apple Music, so I have to individually purchase those pieces I decide to accompany on my banjo. But that is a very small added cost for the time ASD saves when learning the song. Besides having quick and easy control of pitch and speed, the setting of focused sections of songs is very easy—I was setting focused loops on the fly the first night of practice using ASD. Each loop only took seconds to create and are automatically organized under a disc looking icon linked to the song. Having the loops organized with each song like that is one of the many details that make using ASD intuitive and effective. I do not typically leave reviews—less than a half dozen made in my lifetime across all platforms—so this review is a sign of how impressive and helpful this app truly is. Thanks for this great product!


Greedy company lacks re-download  dcb-111  1 star

I switched to a new phone after purchasing the app for $15 and reached out to roni music to see if I could download the app on my new phone. They said no!! One star for greed! I already paid for the app why would switching devices make a difference? Simply deactivate the old app! Find another slow down app that actually cooperated with its paying customers!


It truly is Amazing!  afarmerguitar  5 star

I think this is the first review I have ever written. Normally I wouldn’t go out of my way, but this app has truly revolutionized the way I teach and practice. Everyone who plays an instrument needs this app! Also, a couple of days ago, I was having trouble with the app, which was probably due to Spotifys servers being down. I emailed the company and got a quick response and shortly the problem was fixed. It was at that moment, I realized how much I depend on this app! Worth everything you pay and more!


Bugs  JuliaBeb  3 star

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.


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.


Awesome  fueledbykyle  5 star

Been using ASD on both computer and mobile for years and love it's functionality and simplicity. Spotify support and WiFi Import are awesome. Would love to see the ability to rename files.
