What’s the hardest "Aha!" moment to design for a first-time user?

Hey PH community! Büşra here, co-founder and designer of Yemake.

We launched today, and I’ve been reflecting on our design journey. Our core feature turns cooking videos into step-by-step recipes via the native iOS Share button.

As a designer, the hardest part was realizing that reading about the app doesn't work—users only get the "Aha!" moment when they actually see the video transition into a clean UI in real-time.

How do you design for that immediate visual "Aha!" moment when onboarding a first-time user? Do you rely on tooltips, video demos, or just pure intuitive UI?
