Jamerator vs NinjamZap

Open Jamerator, get a chord progression, press play, and start playing. If friends are around, everyone jams to the same chords on the same beat. RHYTHM Swipe for a fresh progression with the shapes to play it. Swipe back to any jam you've played. Set the tempo, move the key or add a capo, pick a count-in, and hear the guitar, the click, or both. LEAD The scales that fit your progression, lit up on a fretboard. Chord tones highlight as the chart plays so you always know where to land. TUNER A built-in tuner with a fine-tune meter. One tap away, no switching apps. JAM TOGETHER One phone starts a jam and nearby friends join over Bluetooth or Wi-Fi. No accounts, no internet. Everyone sees the same chords and starts on the same beat, and anyone can roll the next progression. Made for practice sessions, band rehearsals, and bonfires. Jamerator is free with ads, and a one-time purchase removes them forever.

NinjamZap brings real-time online jamming to your iPhone and iPad — now 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 iOS NINJAM client, and the first NINJAM client of any kind to support live video.
