Fitbit founders launch AI platform for family health tracking

Somewhere between Slack messages and soccer practice, millions of Americans are also managing Mom’s meds. And Fitbit founders James Park and Eric Friedman think AI can help.

On Tuesday, the entrepreneurs launched a new app called Luffu that’s aimed at pulling each family’s scattered health info and consolidating it into one place, where AI tools can help answer any questions from caregivers.

Why it’s a big deal: Nearly 1 in 4 US adults (63 million Americans) are family caregivers, a number that’s jumped 45% over the past decade. Many of these caregivers are simultaneously juggling jobs, kids, and long-distance care for aging relatives with little formal support.

How it works

Families can log health information on Luffu using voice, text, or photos, with AI automatically extracting and organizing key details. The system then learns day-to-day patterns across multiple people and flags issues like missed medications, unusual vitals, or changes in sleep and activity.

• Users can also ask plain-language questions like: “Is Dad’s new meal plan affecting his blood pressure?” and receive tailored answers or charts.
• Luffu is a digital-only service for the time being, with future plans for hardware devices.

Big picture: More than a quarter of US adults (27%) report having used AI at least once to get health information, with another quarter (24%) saying they might use it in the future, according to a recent NORC study. Meanwhile, OpenAI says 40+ million Americans use ChatGPT daily to ask questions about healthcare.
