The founders of Fitbit have a new startup. Two years later leaving GoogleJames Park and Eric Friedman announced a new platform that shifts the focus from the individual to the family. They say the Luffu mobile app “uses AI quietly in the background” to collect and organize family health information.

“At Fitbit, we focused on personal health – but after Fitbit, health for me became bigger than thinking about myself,” Park SAYS in a press release. The app is specifically focused on the “CEO of the family” — the person who manages appointments, prescriptions and other health-related tasks.

But the definition of family is not limited to parents raising children. The company sees its tool as especially valuable for caregivers in their 40s and 50s who may be managing the needs of aging parents and children. It even tracks pets’ health habits.

“We manage to care for three generations – children at home, busy middle-aged parents, and my father in his 80s who suffers from diabetes and still wants to remain independent,” Friedman wrote. “And the moments that matter most are often the most chaotic: a fever at night, a sudden visit to urgent care, a doctor asking a question you can’t answer right away because the details are scattered.”

The company claims that the app’s AI is “not a chatbot layer.” Instead, it serves as a “guardian” — actively monitoring changes silently in the background. AI then provides insights and triggers alerts when something is amiss. You can also ask health data questions in the app using plain language (therefore, there is a chatbot of sorts) and share the data with family members.

The company clearly wants to make data entry as easy as possible. Luffu allows family members to log information using voice, text or photos. It integrates with fitness platforms like Apple Health and Fitbit. And the company eventually wants to expand into a hardware ecosystem — presumably, devices that make collecting health data easier.

Speaking about data collection, Luffu says, “Users are always in control of exactly what is shared, with whom, and privacy and security are paramount for all family data.” In addition, the company SPOKE Axios that users can choose whether their data is used to train its AI. On the other hand, Big Tech has repeatedly shown that the most egregious data collection methods are often wrapped in comforting language. So, at the very least, I would take their pitch with a grain of salt and, above all, make sure that each family member knows exactly what they are agreeing to. Actually, this is a for-profit company, and we don’t know its monetization strategy yet.

Luffu is currently in limited public beta. You can learn more and sign up for the waitlist at company website.
