Great tool

Think this tool is great but it needs two features to be perfect. 1) key board should display notes (A, B, etc.) 2) video can go full screen!

Works great, but missing one key feature

I’m glad that an app where I can adjust the pitch of the audio on some of the videos exist and I would use it regularly if it didn’t miss one key feature: the ability to save it in my photos. I find it ridiculous that when it comes to saving, I’m limited to the iCloud, Dropbox, email or a folder where other apps can’t get access to. If it just allowed users to save it in photos, I would give this app five stars.

Hi MrGrimmace - Thanks for the nice feedback, we're glad that you're enjoying the app! Unfortunately, video export is currently not available in the app, so you won't be able to export it to your Photos. We'll consider creating this option in future updates.

Love the idea. Doesn't work with Apple Music

As a drummer I'd love to slow down some of my favorite solos and breaks so that I can transcribe them and practice them later. Unfortunately, none of my saved music can be accessed through this app. My playlists show up, but no songs appear in them and when I search my library nothing comes up. I have many songs downloaded on my phone downloaded from Apple Music, but still nothing seems to work.
Very disappointing, as I see great potential in the app, but unfortunately it won't even allow me to use it

We're sorry for the frustration, Tracks from Apple Music cannot be loaded into AudioStretch due to DRM (Digital Rights Management). You can however load songs that you've bought from iTunes or copied into iTunes from a CD which are synced to your iPhone's Music Library. Email for help, anytime.
