Social Fitness App User Profile

An iPhone mockup in portrait mode showing a user profile page in a social fitness app, dark mode. At the top, a full-bleed header image showing an abstract dark-gradient athletic texture. Over the header, a circular profile photo of a silhouetted runner. Below the header, the user's display name "Marcus V." in bold white 24 px, and a subtitle "Marathon Runner · Berlin" in gray. Three stat chips in a row: "Runs 284", "Followers 1.2K", "Following 309" — each chip in a dark card with white number and gray label. A short bio line: "Chasing PRs and sunrises. 🌅" (render the sunrise emoji). A coral "Follow" button and a ghost "Message" button. Below, a tabbed section: "Activity" (active, underline indicator), "Achievements", "Gear". The Activity feed shows three run-summary cards: each card has a map route thumbnail (simplified abstract path on dark background), run title "Morning 10K", stats "10.2 km · 54:32 · 487 kcal", and a timestamp. Color palette: #0D0F14 background, coral #FF6B6B accents, white text, dark card surfaces.
