Jam Tuner: Metronome & Looper

FranJAM Apps

About this app

Tune, keep time and jam over your own loops, all in one app made for guitarists. No ads, no account, no subscription.

TUNER
• Guitar, bass, ukulele, violin, viola, cello, double bass, mandolin and banjo, with 20 tunings including Drop D, DADGAD and open tunings
• Chromatic mode for any instrument
• Precise, steady readings that ignore the sharp attack of a fresh pluck
• Tap a string to hear its reference note, at the volume you choose
• A clear sound and a green light when a string is in tune, and a celebration when they all are
• Contact mode: rest the phone on the guitar body and it only listens to your guitar, even in a noisy room
• Adjustable A4 reference, and exact cents and Hz when you want them

METRONOME
• Turn the dial, step by one, or tap the tempo
• Any time signature, from 1 to 12 beats, in quarters, halves or eighths (6/8 gets its natural accents)
• Subdivisions: eighths, off-beats, triplets, shuffle and sixteenths
• Feel the beat: vibration you notice with the phone in your pocket
• Silent mode: follow the pulse on screen with sound and vibration off
• Keeps playing with the screen off
• Speed up: the tempo rises by itself every few bars until it reaches your target

LOOPER
• Record 1 to 32 bars after a one- or two-bar count-in, or play freely and tap Stop on the last bar, and it loops seamlessly
• Lines your take up with the click automatically, so it sits on the beat
• The screen flashes on every beat, so you can record without the click
• Add up to 3 layers on top (cleanest with headphones)
• See your input level as you record, and where the sound comes from and goes
• Save your loops with the tempo they were recorded at, play them back any time
• Share them with friends, band mates or your teacher, and import the loops they send you

BACKING TRACKS
• Import songs or jam tracks from your phone, several at once, and play along at full length
• Slow it down or speed it up without changing the pitch
• Repeat the hard part over and over with an A–B section
• Each track remembers its speed and section for next time

INTONATION
• A guided check of your guitar or bass intonation at the 12th fret
• Tells you which saddles to move, which way and roughly how far

PRIVATE BY DESIGN
Sound is processed on your phone. Nothing is uploaded, there is no account and no tracking. The loops you save stay on your phone until you share or delete them. Back up your loops and tracks to one file, and restore them on any phone.
