TwoToJazz offers you in-app help. Simply press the menu icon at the right end of the toolbar, and then press the help button (the "?" icon). On the help page, you see a large box on the top/left corner of the page. This box is a mini version of your canvas that you can practice over by following the instructions shown in the box. There are rows of smaller boxes on the right and bottom sides of the practice box. Each row is associated with a bundle of related features. Each feature has a button that when pressed activates a practice session in the practice box. The help page also shows you which features are unlocked on your device. Remember: a pink bar under a bundle of features means they are locked, and and a blue bar means they are unlocked. To unlock a bundle of features, press the "Unlock" button on the bar below it, and make a corresponding in-app purchase. You also have the option to Unlock All TwoToJazz Features with a single in-App purchase.If you need more general help, for example about what each button of the toolbar does, press the "More Help" button. Finally refer to the FAQ section below for further help.
