Do I need a guitar?
No. ChordCrack trains chord recognition by sound. Your iPhone or iPad is all you need; headphones can help you hear the details.
Where should I start?
Try a five-round Daily Challenge with basic chords. Choose focused practice when you want more time with major, minor, power, barre or blues chords. First-session tips explain listening, hints and scoring, and you can revisit the tutorial in Settings.
How do hints work?
Hints reveal more of the chord through slower playback, individual string sounds and finger positions. Hints cost points, and you can use them when you need a hand. Pause, resume, restart or quit a session from the pause menu.
Can I practice offline?
Download chord audio in Settings while connected and let the download finish before going offline. Cached audio supports practice. Sign-in, friends, leaderboards and cloud updates require internet access.
Can I play with friends?
Add friends by username and compare stats they choose to share. Leaderboard visibility is a separate privacy choice. Practice is individual: there are no live head-to-head matches or shared lobbies.
Is my progress saved?
Practice progress is saved locally, and account features support online stats. Review your scores and accuracy in the app. Online updates require a connection.
How do I report a problem?
Email support@chordcrack.com with your device type, app version and what happened. Settings includes sound, downloaded audio and privacy controls. See our Privacy Policy for details.
