NinjamZap brings real-time online jamming to iPhone, iPad and Mac — with live video. Connect to any NINJAM server, pick a username, and play music with people around the world. Free, no ads, 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 NINJAM client for iPhone, iPad and Mac, and the first NINJAM client of any kind with live video.
