I use this to practice drumming

I use this to practice drums, I can slow down the song to learn the groove, then speed it up as I become competent with the score.
Love how the pitch doesn’t change with the speed changes.

Practice Perfect; Easy to use; Love it!

Update: Very very sad that this app,is no longer supported. There seems to be no substitute. And it is great.
Original review: I record scales etc from my Yamaha keyboard using Tempo Slowmo, and practice cello intonation slowly at first then speeding up bit by bit. I also record youtube audio from my computer onto my ipad mini and practice using TS. My practicing has improved 1000%! I would love to be able to import from Spotify. Thank you to the developer. I really needed this app (easy!)

PITCH Function is no longer working.

After satisfactorily using this app for several years the PITCH function no longer works correctly—frequently with the Pitch button no longer appearing at all. I deleted and reloaded the app and no improvement. The button occasionally appears, (depending on which of my downloaded iTunes selections I load), but does not reliably function. When it does not appear, I can go to the Shopping basket (Store) REMOVE it, then INSTALL it, and it will reappear—but does not function (it will display incremental semitone changes, but will not change the audio). It was an invaluable tool for rehearsing or arranging a tune in a key other than the original key, but that function now seems to have largely disappeared.

Should’ve believed Sept’s comment

Purchased the pitch didn’t work, the app doesn’t export either

Suddenly stopped working

I used to love this app and used & recommended it for years. Recently it started to just randomly start ignoring loop markers. Sometimes it does sometimes it doesn’t. Sometimes restarting the app works and sometimes it doesn’t. It also stopped slowing down the song. This app used to work flawlessly every time! I’m heartbroken, but I’m now searching for a replacement :(

What the heck

I used to love this app it helps me speed and slow things down for my group fitness class but now it’s not working!!!!!

Playlist Crashes App

I would give this app a 5 start review.
However, after purchasing the playlist option the app has been refusing to load tracks or crashing and even loading the wrong tracks but with the correct track name!
I had to remove the playlist function to stop this.
Shame as I use to love this app.
Maybe an update will fix this.
I have tried deleting and reinstalling many times but it does not fix the issue.

Update: Sept 2025.
Ongoing issue with adverts. I paid to have these remove however every time I use it there are adverts and I have to hit ‘restore purchase’.
I would like a refund for my initial playlist purchase and also the remove adverts.
Total pain.

Update: I’ve given up on this app and requested a refund.
It has become unusable. Despite paying to remove apps and to add the playlist feature, it failed to remember at launch and need resetting every time.
That added to the random crashes and other glitches I’ve given up and moved to Audio Stretch Lite. This is amazing. And works every time.

Love this app BUT suddenly not working correctly

I have been using this app for MANY years (I think almost 10) and absolutely love it! However, last week it suddenly stopped slowing down the tempo. I tried closing and reopening it - no change. I tried using a different track - no change.

Today I deleted the app and redownloaded it. Now it still doesn’t slow down correctly, but now I have ads that I didn’t before.

I tried the support link but all I could find was a description of features and other apps by the developer - no contact info. So if you see this please help me figure out how to fix this issue!

THREE Fatal Flaws

There are two (EDIT: THREE) fatal flaws which I felt deserved giving this app a 2-star rating (I’m changing this to one after discovering a third issue and having no way to contact the developer)

1. It has a resolution of SECONDS meaning you can't place loop markers correctly.

2. While you can adjust the speed, you can't adjust the pitch. So all those songs tuned to Eb - you'll need to retune your guitar.

3. After this app loops a section a few times, it stops looping permanently.

Song loading screen goes away!!!! fix this!

I hope they can fix the bug because I can’t load songs into it from my library. The load screen goes away in a fifth of a second. bug! pretty much makes it useless.

Are you serious?

This was designed by someone who wanted to ruin your life. Like embarrassing level non-function. Just delete it. Run from it. Forget that it exists. Unless you want to connect the app to your Dropbox, create a special little folder for the app to access, upload any music you need to the special little Dropbox folder, then download from Dropbox to the app…. Only to find out the app doesn’t work anyway. GOOD LUCK, EVERYBODY! 👎

Song loading screen goes away

I hope they can fix the bug because I can’t load songs into it from my library. The load screen goes away in a fifth of a second. bug!

Honestly, my most used app for a while

I’ve done just about everything with this app:

-used it to slow down songs to practice and pick out notes that I’m not hearing at full speed
-showed other musicians what a song would sound like a half step down (or whatever different key) for covers
-when I’m sick with an ear infection, I can take a song and put it in here, take semitones down to hear it at my brain’s known key of the song to avoid pitch dissonance

Love it, I think it needs some efficiency love and some UI upgrades but I’ll still use it!

Bugs

Hello!

I have been using this app for about 6 years.

The app never seems to remember that I have previous purchases. In other words I ALWAYS have to Restore previous purchases.

Please fix. I’ve spent too much money and have used this app for too long to deal with the same issues for 3 years straight, It appears the devs of this app aren’t actively working on it. I will continue posting this review, lowering the number of stars each time until this is fixed.

Thanks

No longer works

This app was fantastic, a great tool for teaching/learning music. I assume the issue with loading songs from iTunes comes from copyright issues. Really unfortunate.

It’s a great app, but

It’s been three years. It’s probably time for an update.

Good Features, difficult to use

This app is great for playing music at slower speeds and looping different portions of the track. I use it all the time when I teach dance classes or rehearse choreography. I wish there were an easier way to download songs. I also can’t seem to delete songs from the app once I no longer want to use them, as the delete feature doesn’t seem to be working?

Used to love it, now it isn’t supported

Man, this app was amazing back in 2014. I could let my imagination run wild with it. Now none of my purchases can be restored, and when I reinstalled they were there but don’t work. Really loved the pitch control.

INSANELY GOOD

I never, ever, ever leave a review for an app. But I love this thing! Served me well for years!!! Just fun when I’ve had a little blaze, never let me down!

not working at all

I am using MacBook Air M2 chip iOS 14.6.1 version. There are many problems with compatibility.
I feel like there is no function that works properly.
