Features
What is inside
4 instruments · 16 tunings · in every key
Identify Chord: the reverse path
Mark the shape on the on-screen neck and the app names the chord and the other possible readings.
41 chord types across 12 keys
218,399 voicings and inversions — each with its diagram, fingering and audio.
57 scales mapped
40,406 mapped scale shapes across the whole neck, with fingerings and guide tones.
Strumming & fingerpicking
Grooves by style with audio in time — from pop to bossa nova.
Precision tuner
A chromatic tuner with reference tones, ready before every session.
Metronome
Tap tempo and subdivisions to drill every change in time.
Transpose & capo
Move the whole chart to another key and put the capo wherever you like — both are free, and inside a chart the app even suggests the fret that opens the most shapes. Letting it find the best capo on its own comes with Pro.
Reharmonize
It starts free, at the gentle levels: every swap comes with the roman numeral, the diagram and the why. The bold levels with all 16 named techniques, and reharmonizing a whole chart in one go, come with Pro.
Your song charts
Paste a ready-made chart and it becomes sections; play along with the metronome at that song’s saved tempo and read it in stage mode. 20 songs on the free plan; stage mode comes with Pro.

Charts
Your chart, from rehearsal to the stage
The song you play becomes a rehearsal notebook: you paste the chart from anywhere, it turns into named sections, and the app remembers how YOU play that song — without ever rewriting the text you pasted.
Paste it and get the structure
Every bracketed marker opens a section — Intro, Verse, Chorus, Bridge, Solo or Ending — and a “2x” in the header already becomes the repeat.
Repeats and modulation per section
Each part plays 1 to 8 times and can go up or down by as much as 12 semitones — that is how “the last chorus goes up a half step”.
A performance road map
The reading follows the order the song really sounds in, holds the screen on a repeating section when it fits, and obeys the jumps back to the middle and out to the ending (D.S. and Coda).
Transpose and capo without breaking anything
The original text is never rewritten: reset it and the song comes back exactly as it arrived.
A key that says where it came from
The app tells you whether you set the key, whether it froze at creation or whether it is a guess — and with too few distinct chords it would rather say “not sure” than print a wrong key.
The chart never wraps
The chord stays over the right syllable, and stage mode enlarges everything so you can read it from a distance (the text size is your call while you paste or edit the chart).
Offline
Why offline matters
Music happens where the signal doesn't. The diagrams, scales and audio are generated on the device itself, so chords, scales and sound work with no connection: nothing to load, nothing to drop out mid-rehearsal.
- In the rehearsal room, even with no Wi-Fi
- On stage, never waiting on a signal
- On the road, travelling, anywhere
Your account
Your account is yours
You use the app without an account; it is only required to subscribe. With one, you keep a copy of your library, can take it with you and can erase it, all on the Account screen itself, with nobody to ask.
A backup
Sign in and your charts, your chords and your scales get a copy on our servers — change phones and it is all still there.
The same library on every device
“My devices” shows where you signed in, when it was last seen, and a button to disconnect the ones you no longer use (sold, lost, lent out).
Take your data with you
One tap downloads everything we keep about you as a file, to check it or take it anywhere.
Delete it for real
Deleting the account erases your registration, your devices and the copy of your library on our servers. What is saved on the device stays with you.
What we never collect
Location, contacts, photos, files or an advertising identifier. No ads on the site or in the app. On the site, measurement only runs if you accept in the cookie notice.
Accessibility
Made to be heard with a screen reader too
On Android, with TalkBack on, the app says the chord in full, describes each position string by string and lets you choose when a symbol has two readings. Text follows the system size. The iPhone version is on its way.
Chords and scales said in full
“B flat major seventh”, not the symbol spelled out; each position is read string by string, with fret, finger and note.
Search by dictation or in words
Dictate with the phone keyboard or type “B flat 7”; when a symbol has two readings, such as Bb7+, the app shows both and you choose.
Text at your size
Text follows the system font, and the app has a setting of its own. Contrast strengthened in both themes.

Questions
Straight questions, straight answers
Is Pro a subscription?
That is the main way: $6.99/mo or $34.99/yr, with a 14-day free trial on the annual plan and cancel anytime. There is also a lifetime unlock: $174.99, a one-time purchase — pay once, no renewal. The essentials stay free, no ads.
Does it work offline?
Playing does: diagrams, scales and audio are generated on the device. The one thing that needs the internet now and then is confirming the Pro subscription: the app keeps a signed pass good for about 30 days and tolerates roughly 7 more. Go past that with no connection at all and Pro falls back to free until you open the app online once — nothing that is free ever stops.
Which instruments?
Guitar, electric guitar, cavaquinho and ukulele, with 16 tunings in total, in every key.
What does Pro add?
The arpeggio of each position and playing the whole scale; alternate tunings, in the tuner too; saving chords and scales; unlimited charts, with stage mode and the performance script, and reharmonizing the whole chart; syncing across devices; Identify Chord with no daily limit; the cadences beyond the ones open on the free plan; drop 3 and shell in the Jazz Lab; the Bold and Jazz levels of Reharmonize; and the capo search. Seeing and hearing every chord, the scale positions, the tuner in standard tuning, the metronome, the rhythm trainer and transposing are free.
Do I need an account? What happens to my data?
Not to use it. The account is free and keeps your subscription; with Pro, it syncs your library across devices and keeps a copy of it — and it comes with the controls attached: see the devices you signed in on, download everything we keep about you as a file, and delete the account and that copy whenever you like. Without an account, nothing leaves your device.
And this site?
It stays free and open, with chords, scales, strumming patterns and progressions to study in the browser. In the app, each chord comes with the other positions and the sound, along with the tuner and the metronome, and it works offline.
Start free. Go Pro when you want.
The essentials are free; Pro is a subscription in the app, with a 14-day free trial on the annual plan — and there is a lifetime unlock, paid once.
- Your charts with no limit (free keeps 20) — with stage mode and the road map
