UTAORA is a chord-chart viewer and setlist manager for singer-guitarists. ■ Chords that never drift Chords sit exactly above the lyrics. A monospaced layout keeps them aligned no matter how you transpose or change the capo. ■ Transpose and capo, independently Change the key or the capo position separately. Simplify tricky chords into easy shapes with a single toggle. ■ Read ahead, like a songbook Split the view into 2 or 3 columns to see the next phrases coming, so your playing never stalls. On iPad, go landscape and spread it wide like a music stand on your piano. ■ On stage, just run your setlist Arrange songs in order and flow from top to bottom. No fumbling during the show. ■ Never guess a fingering Look up any chord in the built-in dictionary. Guitar, ukulele, and piano supported. ■ Your songs stay safe Automatic on-device backup protects your precious song data. For iPhone and iPad. For busking outside or practicing at home.
