We have a lot of different training exercises the user can do in the app, and there is a lot of overlap from one to the next.

We're using data-binding to bundle a lot of the same patterns together, and then nested components for the score screen, timer, and user inputs.

Being able to adjust the difficulty easily with data-binding is essential, and a similar technique was used with data-binding to achieve the dynamic ticking on the score screen based on the user's score.

Lots learned and more ideas to come!
