RepeatLab in Action
“This app is simply amazing! I love it! I use it every day. It's really intuitive and extremely easy to use! It works flawlessly and I've never experienced any problems.”
“Absolutely helpful app. I especially love that the new version also allows you to work with videos.”
“This app works well and the developer is keen to take suggestions for improvement and act on them. That's a very progressive attitude, and it will unquestionably lead to the evolution of an excellent product over time.”
“At last an app that’s so easy to use and so affordable. I wished this came years ago. Oh my gosh beautiful layout and so easy to use.”
“After using several different apps for slowing down songs this app does even more, it lets you loop certain parts of a song many times which you are able to arrange in any order and rename. Simple to use and the audio doesn’t suffer. Brilliant 👌”
Features
Precise A-B Looping
Tap to mark the start and end of any tricky section and loop it instantly. Fine-tune to the millisecond by typing exact times or dragging the interactive waveform. Set up multiple named, color-coded loops per song and jump between them from a visual timeline — even from your lock screen, notification, or Bluetooth controls.
Free: 1 loop per song · Pro: unlimited loops & reordering
Slow Down Without Changing the Pitch
Practice at your own pace. Slow music down to 0.5× or push it to 2.0× in fine 0.1 steps — the tempo changes, the pitch stays true. Switch between a simple multiplier or exact BPM mode (up to 400 BPM), and use Tap Tempo to detect a song’s BPM by tapping along.
Pro feature
Change the Key, Not the Speed
Shift the pitch of any song up or down by up to 12 semitones without affecting the tempo — perfect for transposing a song to a different key or matching your instrument’s tuning. Your pitch setting is saved per song, and it combines freely with speed control.

See Every Beat on the Waveform
A clear waveform for every song shows played vs. unplayed audio and all your loop markers. Drag to scrub precisely and zoom from 0.25× to 5× to place loop points on the exact note.
