Hear the triad.
Find it on the
fretboard.
Ear training, fretboard practice, and a jam-along backing-track engine — built around a single music kernel that's reactive to custom tunings, 7- and 8-string, and lefty.
$49.99 · One time · No subscription · No accounts
The Jam fretboard knows where every note lands — and which chord owns it.
Three position zones — OPEN, MID, HIGH — light up the same chord in three places, so your hand always has somewhere to go.
One music engine,
five surfaces.
A chord you find in Theory turns into a drill in Train, and a backing track in Jam — the same kernel under all of them.
- 01
Train
Ear, fretboard, and mic — drilled separately or together.
Nine drill modes — root, quality, inversion, play-back, interval ID, progression, find/play the note, mode ID. Pure ear, pure fretboard, or both at once.
- 02
Jam
Backing tracks that show you exactly where to land.
Fifty curated chord progressions across rock, blues, jazz, funk, Latin, metal, and odd meter — with the Jam fretboard overlay marking which notes belong to each chord, in three positions at once.
- 03
Theory
Triads, sevenths, modes, and the Circle of Fifths — interactive.
Triads, 7ths, 9ths, 13ths; eleven modes; intervals; Circle of Fifths. Click a chord to see voicings; click a key to walk its modes one finger at a time.
- 04
Tools
The metronome and tuner you'd actually pick up.
Metronome from 30–260 BPM with odd meters. Pitch-detecting tuner with reference pitches. Chord and scale dictionaries, and a reverse chord finder for when you forget the name.
- 05
Progress
Streaks, accuracy, and a heat-bar of every position you've worked.
Streaks, accuracy, a 14-day chart, and per-mode heat bars showing exactly which corners of the neck you've practiced. Stays on your device; rides Android Auto Backup to your next phone.
An indie dev.
A guitar player.
Built primarily
for myself.
I built OmniFret because I couldn't find an ear-trainer and fretboard tool that wasn't a subscription, hadn't gone stale, or didn't try to upsell me at every turn. Now it exists — for me, and for you, if you want it.
Every dollar from a $49.99 unlock goes to support one person and the next round of updates — not a corporation that has to ship features to appease VCs, and not a board that needs the line to go up.
Pay once. Support an indie dev. Get an app that keeps getting better because the same person who built it still picks up a guitar most days.

Quick answers.
- Q · 01
Does it support bass?
- Yes — 4-, 5-, and 6-string bass on the PRO tier, with custom tunings and a tuned-down sub range.
- Q · 02
Is it lefty-friendly?
- One toggle mirrors every fretboard in the app. Drills, the Jam overlay, and the chord/scale dictionaries all flip with it.
- Q · 03
Is it a subscription?
- No. $49.99 one-time, no recurring charge. If you ever reinstall (or get a new phone) Android Auto Backup restores the unlock.
- Q · 04
Does it work offline?
- All of it. Drills, theory, the metronome, and the tuner run fully offline — there's no server to call. Anonymous TelemetryDeck pings (a hashed device id, no IP, no personal data) are the only thing that ever leaves the device.
- Q · 05
What about iOS?
- Android only today. The audio engine, music engine, and billing layer are already cross-platform via Kotlin Multiplatform — iOS is the most likely next port.
