The screen is usually called an onboarding screen or app walkthrough. If it’s the very first screen that introduces features, people also call it a welcome screen or intro screen.

Common names

  • Onboarding screen : the most common term for the first-time setup/intro flow.
  • Walkthrough : a guided tour of the app’s features.
  • Welcome screen : often used when the screen just greets the user before the main app starts.

Practical difference

  • If it’s a sequence of 3–4 swipeable screens, onboarding is the best fit.
  • If it’s a guided tour shown around the app, walkthrough fits better.
  • If it’s a single start page with a “Get Started” button, welcome screen is common.

In app design, the most standard answer is onboarding screen.
