The chart you find is never the chart you play. Cover bands transpose for the singer, cut a verse, rewrite the ending. Cardinal is where your band keeps the version you actually perform. BRING YOUR CHARTS IN Paste chords over lyrics, ChordPro, or bar-line notation — Cardinal reads all three. Import a whole iReal Pro playlist from a single link. Or photograph a page from your gig folder and have the chords read off it. MAKE IT YOURS Transpose a song into the singer's key in one tap. Set a capo and read the shapes under your fingers, without changing what anyone else sees. Edit anything — it's your arrangement, not a reference page. SHARE IT WITH THE BAND Invite your band by email. Everyone reads the same arrangement: your cuts, your key, your ending. BUILT FOR THE STAGE Full screen, screen stays awake, swipe between songs. A red night-vision scheme for dark stages, and text you can size to read at arm's length. Everything works offline — your setlist is there whether or not the venue has signal. FREE Unlimited songs, setlists and bands. The full stage view. Every import except photos. CARDINAL PRO — $4.99/month Photo import beyond your first three, and PDF attachments.
