Design a modern, high-end {argument name="app type" default="fitness app"} landing page and product UI for a brand called {argument name="brand name" default="PulseFit"}.
Create a clean web design mockup that looks like a real SaaS fitness platform and mobile companion app. The design should feel premium, motivating, and easy to use, with a polished UI/UX style similar to top-tier health and wellness apps.
Include:
- A hero section with bold headline, short subheadline, strong call-to-action button, and app preview
- Dashboard UI showing daily activity, calories burned, workout streak, heart rate, step count, and progress rings
- Workout program cards for strength, cardio, mobility, and recovery
