A real band in your pocket.

It plays your songs, writes its own, and never needs the internet.

Its own songsA radio that composes as it goes: lofi, jazz, funk, rock and more. Every tape is new, and every tape has a code that brings the same song back.
On stageSet lists, a chart you can read from across the room, and a foot pedal for the fill, the extra chorus and the ending.

Coming to the App Store · early 2027

The full Bandalong, for iPhone, iPad and Mac.

What you can play here is a taste. The app is the whole band:

Every station. Twenty-nine of them, from lofi and smoky jazz to funk, reggae, country, gospel, surf and rock and roll.
The whole Songbook, and as many of your own songs as you like, in any style, key and tempo.
A gig in your pocket. Set lists, a stage view you can read from across the room, and a foot pedal for the fill, one more chorus and the ending.
Take the music with you. Recordings, each player on a separate track, MIDI and printed lead sheets.
No internet needed. The band composes and plays on your device, on a plane or in a basement.

Bandalong on a phone: a cassette turning, the tape's name, its chord and the stations.

Bandalong on a Mac: the Songbook, a tune's chart, and the band's mixer.

One purchase. No subscription. Buy it once and it's yours on iPhone, iPad and Mac.

Email us and we'll tell you the day it's out. We'll use your address for that one message and nothing else.

What we promise

It works in airplane mode. The apps compose and play on your device.
It doesn't know who you are. No account, no ads, no tracking. The apps collect nothing at all; this website only counts visits, without cookies.
Every sound is a licensed recording of a real instrument. The songs are written by rules, and nothing was trained on anyone's music.
