The founders of Fitbit introduce Luffu, a way to integrate your family’s health data
The founders of Fitbit have a new beginning. Two years after leaving Google, James Park and Eric Friedman announced a new platform that shifts the focus from the individual to the family. They say Luffu’s mobile app “quietly uses AI behind the scenes” to collect and organize family health information.
“At Fitbit, we focus on personal health – but after Fitbit, life for me became bigger than thinking about me,” Park said in a press release. The app is mainly focused on the “CEO of the family” – the person in charge of 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 particularly important to caregivers in their 40s and 50s who may be managing the needs of both elderly parents and children. It even tracks the health habits of pets.
“We manage care for three generations — kids at home, busy parents in between, and an 80-year-old dad who lives with diabetes and still wants to be independent,” Friedman wrote. “And the most important moments are often the most chaotic: the late-night fever, the urgent emergency visit, the doctor asking questions that you can’t answer immediately because the information is scattered.”

The company says the app’s AI is “not a chatbot layer.” Instead, it acts as a “guardian” — continuously monitoring changes quietly in the background. AI then provides insights and triggers alerts if something goes wrong. You can also ask the app health data questions using simple language (so, there is some kind of chatbot) and share the data with family members.
The company obviously wants to make data entry as easy as possible. Luffu allows family members to enter information using voice, text or images. It also includes health platforms such as Apple Health and Fitbit. And the company eventually wants to expand into a hardware ecosystem — perhaps, devices that make health data collection even easier.
Speaking about data collection, Luffu says, “Users are always in control of what is shared with whom, and privacy and security are paramount to all family data.” In addition, the company told Axios that users can choose whether their data is used to train its AI. On the other hand, Big Tech has repeatedly shown that its worst data collection practices are always wrapped in comforting language. So, at the very least, I would take their tone with a grain of salt and, most importantly, make sure each family member knew exactly what they were agreeing to. After all, this is a for-profit company, and we don’t yet know its monetization strategy.
Luffu is currently taking waitlist registrations for the upcoming limited public beta. You can learn more and sign up for the waiting list on the company’s website.
Update, February 3, 2026, 1:14PM ET: This story has been updated to note that Luffu’s public beta hasn’t started yet, but you can sign up for a waiting list to finally get access when it does.
