Slow Down Music: Song Looper

Slow down any song without changing the pitch, loop the exact bars you're stuck on, and come in on time with a count-in. Private and on-device, no account needed.

Learn songs the way they're built: section by section.

Looper splits any song into its musical sections on a beat grid. Pick the part you're stuck on, loop it as many times as you need, and slow it down without changing the pitch. No more scrubbing back and forth to find the start of the solo.

SEE THE STRUCTURE Import an MP3, M4A, WAV, or FLAC file and Looper analyzes it right on your iPhone. In seconds you get a color-coded map of the song: intro, verses, choruses, solos, all on a beat grid you can follow at a glance. Tap the speaker on any section to hear it before you practice.

LOOP THE HARD PARTS Tap a section, or select several in a row, and loop them 2, 4, or 8 times, or endlessly until they stick. Transitions are seamless, so you stay locked into the groove instead of waiting for the track to restart.

SLOW IT DOWN, KEEP THE PITCH Looper detects the song's tempo, so you practice in BPM, not percentages. Step down 5 BPM at a time while you learn a riff, then nudge it back up 1 BPM at a time until you're playing at full speed, or faster. Anywhere from half speed to double speed, the pitch never changes.

COME IN ON TIME Turn on the count-in and get one bar of clicks at your practice tempo, matched to the song's meter, before the loop starts. You begin on the downbeat, not scrambling after it.

MAKE IT YOURS Rename sections so they match the song. Move a boundary along the beat grid if the analysis put it a bar early. If the whole song is off by a beat, shift every section at once with a single tap.

PRACTICE YOUR WAY Prop your iPhone on a music stand in portrait, or turn it sideways for a wider view of the song. Open audio files straight from the Files app or other apps, or start with a built-in demo song.

YOUR LIBRARY, BACKED UP Your tracks, section edits, and practice tempos are saved to your private iCloud account, so your library follows you to a new iPhone.

PRIVATE BY DESIGN Everything happens on your device. Looper collects no data and has no accounts, no ads, no tracking, and no third-party code. Your music never leaves your hands.

Whether you play guitar, bass, piano, drums, saxophone, violin, or anything else, Looper turns any recording into a practice tool for working out parts by ear. Pick a song and get to work.
