NinjamZap

The first mobile NINJAM client for iOS. Connect to any NINJAM server and jam with musicians around the world — right from your iPhone or iPad. No account required.

NinjamZap brings real-time online jamming to your iPhone and iPad. Connect to any NINJAM server, pick a username, and play music with people around the world — no studio required.

NINJAM is a proven protocol for internet music collaboration, used by musicians for over 15 years. Instead of fighting network latency, NINJAM embraces it: everyone plays along to a shared metronome, and you hear what others played in the previous interval. The result is a surprisingly natural and creative way to make music together.

NinjamZap is the first native iOS client for NINJAM, built from the ground up for mobile.
