Barline
Coming soon to iPhone
Loop the bars,
not the seconds.
Barline is a practice looper for learning songs by ear. Import a track you own and it maps the bars, beats, sections and key, on your phone. Tap a section, slow it down without changing the key, and repeat until it’s yours.

How it works
Four moves.
One loop.
Everything happens on one screen: the bar you’re on at the top, the song’s map under it, then speed and pitch. There’s no timeline to scrub and no timestamps to type, because the song has already been counted for you.
The short version
It counts the way you do.
Other loopers give you a waveform and two handles. Barline gives you bars, so what repeats is a phrase, the pickup included, and never a slice that starts mid-beat.
The map is made on your phone
Bars, beats, sections and key come from Apple’s on-device music analysis. The file never leaves the handset. There is no account, no Mirentha server and no analytics. We can’t see what you’re learning.
If the ones are wrong, tell it
Analysis sometimes lands the bar line on beat three. Play the song, tap on two or three beats you’re sure are the one, and Barline re-lays the whole grid to match. Every section and every saved loop moves with it.
Price
Three songs free, then a small subscription.
Every feature works on the first three songs: loops, ramps, markers, the lot, for as long as you like. If you want a fourth, Barline Unlimited lifts the limit for £2.99 a month or £19.99 a year. Nothing you’ve saved is ever held back: if the subscription lapses, every song you’ve added stays playable.
