The way we design health apps is shaping who stays healthy and who gets left behind.
In this conversation, Amber Vodegel, founder of the world’s largest pregnancy app, Pregnancy Plus, and now CEO of 28x, challenges how women’s health technology is built, funded, and trusted.
Amber argues that health knowledge shouldn’t sit behind a paywall or be traded for personal data. With around 800 million people menstruating every day, access and trust matter.
She’s designing a different path: on-device AI that keeps data on your phone, content at multiple reading levels so information is understandable without dumbing it down, and interfaces women feel comfortable opening anywhere—ditching traffic-light cues that confuse and stigmatise.
We explore how 28x aims to sit between the NHS and TikTok—combining clinically validated content with formats people actually use. Amber opens up her playbook: a year of research-before-build, user research with teenagers and low-literacy groups, and a product strategy where cycle tracking earns attention for evidence-based education.
She also explains a circular business model: free at the point of use, ethical sponsorships and pay-it-forward contributions, and reinvesting profits into period products, education, and female founders globally.
If you are interested in designing for trust, who should own health data, or how tiny on-device AI could reshape digital health, this episode offers a practical, provocative blueprint. It’s a story about turning design from surface polish into system change—and building technology that serves people first.
