Function Health direct ad

You barely need a second to get what Function Health is offering. The ad spells it out cleanly: one membership, 100+ lab tests, $42 a month. No fluff. No confusion. Just value.

Why It Works

• Uses the Rule of One: one offer, one price, one clear benefit
• Big bold font stops the scroll
• Transparent pricing removes friction
• Social proof (10M+ tests, 5 stars) builds instant trust
• Subtle visuals keep focus on the message

Real World Examples

• Netflix: “Watch anywhere. Cancel anytime.”
• Calm App: “Sleep more. Stress less. Live better.”
• Dollar Shave Club: “A great shave for a few bucks a month.”
• Blinkist: “15-minute reads of bestselling books.”

Clarity always converts better than cleverness.
