Guitar Charts Creator for iPad is usually $5, but it is free today!
Guitar Charts Creator lets you create your own custom chord charts and diagrams, right on the iPad. You can create stacks of charts and add as many chords as you like. This app is smart, so it will help you work out what the name of the chord is (if you're not sure)!
If you practice guitar, no doubt you have a stack of hand-drawn guitar chords or chord books lying around.
Now you can cram all of that information onto your iPad so you can take it with you anywhere!
