Tempo SlowMo will then load the audio file which you can then play, pause, slow down and speed up to your hearts content. Tempo SlowMo also has a feature allowing you to drop markers at any point in the track so that you can quickly skip back to that point if there is a particular bit of a track you are trying to master. Special Loop Markers allow you to loop part of a track if you need to master a specific section. Start and End Track Markers allow you to override the point where a track begins and ends.

Love how the pitch doesn’t change with the speed changes. ### 5/5 — Practice Perfect; Easy to use; Love it! *2025-12-06, version 1.5.4* 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!) ### 1/5 — PITCH Function is no longer working. *2025-11-24* 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. ### 1/5 — Should’ve believed Sept’s comment *2025-11-11, version 1.5.4* Purchased the pitch didn’t work, the app doesn’t export either ### 2/5 — Suddenly stopped working *2025-09-28* 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 :( ### 1/5 — What the heck *2025-09-28, version 1.5.4* 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!!!!! ### 1/5 — Playlist Crashes App *2025-09-26, version 1.5.4* 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. ### 5/5 — Love this app BUT suddenly not working correctly *2025-09-25* 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! ### 1/5 — THREE Fatal Flaws *2025-09-12, version 1.5.4* 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. ### 1/5 — Song loading screen goes away!!!! fix this! *2025-08-31, version 1.5.4* 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. ## Frequently asked questions about Tempo SlowMo ### What does Tempo SlowMo do?
