BarLoop

BarLoop is a practice player for musicians. Import a song, and BarLoop finds its tempo, beats and bars so you can learn it bar by bar.

SLOW DOWN WITHOUT CHANGING PITCH • Play from 25 % to 150 % of the original speed — the key stays the same. • High-quality time-stretching, running entirely on your iPhone.

LOOP BY BARS • BarLoop detects the tempo and the bar lines automatically. • Loop 1, 2, 4 or 8 bars with one tap, and jump bar by bar. • Adjust where bar 1 starts and switch between 3/4 and 4/4 if needed.

PRACTICE TOOLS • Metronome clicks that follow the song's beat, even when slowed down. • Transpose ±6 semitones to match your instrument or voice. • Speed, key and bar settings are remembered for every song. • Lock-screen and headphone controls.

YOUR FILES, YOUR DEVICE • Import MP3, M4A, WAV or AIFF files from Files, or use Share → BarLoop from any app. • Add songs from your Mac through Finder file sharing. • No account, no ads, no tracking — nothing leaves your iPhone.

Note: copy-protected (DRM) tracks, such as songs streamed or downloaded from Apple Music, can't be opened.
