In this lesson, we refine the tarot app by introducing related lists and improving how images display. You’ll see how to build interactive references between readings and cards, making your app clickable, connected, and future-proof for analytics like card frequency graphs. We’ll also revisit the “Pull Cards” action button, fix the comma bug with an IF expression, and adjust the layout so your app always displays cleanly. This episode is all about tightening your build, learning to troubleshoot, and polishing your user experience.
