X Guitar is your private songbook: every chord sheet you play, in one clean format, kept on your device or in your own iCloud. With a tuner you can trust built in.
TUNER
• Pluck a string and it finds the one you meant — or pin a string yourself when one has drifted far out of tune.
• Tells you which way to turn: tighten or loosen, and which peg, drawn on your headstock.
• Standard tuning plus Drop D, Open G, DADGAD, half-step down and more, or define your own.
• Reference tone, adjustable A4, sensitivity for noisy rooms, and a large display you can read from a music stand.
• Put a capo on and the targets follow.
ADDING SHEETS
• Photograph or import a screenshot or PDF of a chord sheet and X Guitar reads it on your device — no network, no account, no upload. It gives you a draft to check and fix, not a promise of perfection.
• Paste a link to a page that already has a chord sheet on it and the sheet comes straight in.
• If you have your own API key for a model provider, you can choose to use it for harder pages. That is entirely optional, always asks first, and sends the image only to the provider you named.
CHORD SHEETS
• Chords sit above the words, where they belong. Chord diagrams for every shape in the song.
• Change the key to the one you actually sing in — the app then suggests which shapes to play and where to put the capo, preferring shapes you already know.
• Performance mode scrolls the sheet at your pace, hands free.
• Search by title, artist, or the opening line of the lyrics. Group songs into setlists for a gig.
• Your sheets are plain ChordPro files. Import them, export them, keep them. iCloud sync is optional and uses your own account.
PRIVACY
No account. No analytics. No third-party SDKs. The tuner never records. Recognition runs on your device. The app touches the network in exactly three places, and each one only after you ask it to.
