Centered app promo with biological age phone mockup, floating lifestyle and biomarker cards, and co-founder endorsement.
Summary
A companion-app landing band showcasing biological age UI with overlapping feature callouts and a Learn more CTA.
Visual description
Cream background. Top: lime-green square Do logo, large serif "Do Health," subcopy about biology-powered companion app, circular headshot with "Co-founded with Dr Rangan Chatterjee," and outlined "Learn more" pill. Center: iPhone mockup showing biological age "32" in green glow ring with curved label, age scale, and three metric rows (Energy GOOD, Circulation ACCEPTABLE, Inflammation POOR). Floating cards overlap phone: left blue moon card "Go to bed 1 hour before sleep" with vitamin tags; right green diamond card "HbA1c 34 nmol/l OPTIMAL" with explanatory copy.
Key takeaway
Floating cards annotating a phone mockup explain features without a feature list. Biological age as hero metric creates instant curiosity.
Reuse notes
Strong for wellness apps with quantified health data. Mockup must reflect real product; overlapping cards need responsive simplification.
