## JamGo: メトロノーム Description
JamGo puts three practice essentials in your pocket: a tuner, a metronome and a drum machine. The design is clean and free of distractions, so you can get straight to playing.

TUNER
• Accurate chromatic tuning for guitar, bass, ukulele and violin
• Alternate tunings including Drop D, Half-Step Down, Open G, 5-string B and Low G
• Lights up the string it hears and tells you whether to tighten or loosen
• Ignores room noise so the reading stays steady

METRONOME
• 40–240 BPM in 2/4, 3/4, 4/4 and 6/8
• Tap tempo: tap along to find the speed of any song
• Tap a beat to mute it and practice keeping time yourself
• Digital and mechanical click sounds

DRUM MACHINE
• Program grooves on a step grid with kick, snare, open and closed hi-hat, tom, ride and crash
• Slide on a step to set how hard it hits
• Patterns are humanized, so they sound played rather than programmed
• Chain several bars and choose how many times each one repeats
• Start from built-in Rock, Pop, Funk and Bossa Nova grooves, or save your own to the rhythm library
• Optional one-bar count-in

MADE FOR PRACTICE
• Keeps playing in the background while you read tabs or switch apps
• Keeps the screen awake while you practice
• Designed for both iPhone and iPad
• No account, no ads, no tracking

Grab your instrument and start jamming with JamGo.
