Fitbit Founders Return With Luffu AI App to Simplify Family Health Care

Two years since Fitbit co-founders James Park and Eric Friedman stepped away from the company that made them famous in the fitness industry, they are back with a new and very personal concept. This time, instead of steps, calories, and personal data, they want to change the way families look at health in a world that is becoming increasingly complex and fragmented.
Luffu, their new startup, was announced in a very low-key manner through a blog post. It is an “intelligent family care system” that will start as an app and later develop into hardware devices. The concept is well-timed, as many people today find themselves managing not only their own health information but also that of aging parents, children, spouses, and even pets. Today, this information is usually fragmented across hospital websites, notes apps, messaging services, and paper files. Luffu’s plan is simple but very ambitious: to put it all in one place and use AI to make sense of it without overwhelming the user.
James Park has been very open about the fact that the idea for Luffu came from his own experience of managing his parents’ healthcare remotely. Like many caregivers, he found himself caught between two very uncomfortable options. Checking in too frequently was intrusive and emotionally draining, but being out of the loop was dangerous and stressful. The health apps that existed, Park felt, were not designed for shared care or long-term family management. Luffu, Park says, is the tool he wishes had existed during that period, one that keeps families informed and ready without turning healthcare into surveillance.
What makes Luffu different from other health apps is that it has a shared-first design approach. Unlike other apps that revolve everything around the individual user, Luffu is designed for families and caregivers. Users can track medications, dietary information, symptoms, lab results, appointments, daily activities, and more for multiple family members. This data can be entered in a variety of ways, including voice messages, typed messages, and even photos of test results and medication prescriptions.
It is at the AI layer that Luffu hopes to quietly differentiate itself. Rather than appearing as a flashy chatbot, the AI is instead integrated into the experience. Over time, it learns what is “normal” for each individual, from sleep patterns and vitals to routines and habits. When something changes outside of that normal range, whether it be unusual sleep patterns or missed doses of medication, the app can bring up alerts so that families can take action early rather than taking action late. Users can also ask natural, everyday questions, such as whether a new diet is impacting blood pressure or whether a scheduled dose of medication was administered, and receive context-driven answers based on existing information.
Crucially, the approach taken by Luffu is one that is less focused on constant monitoring and more focused on meaningful awareness. As the founders have described, the aim is to point out what truly matters and to cut through the noise that so often leads to caregiver burnout. This philosophy is also reflected in the name of the app. “Luffu” comes from an old English word for love, underscoring the point that care should be supportive and human, not clinical or intrusive.
Of course, with any service that deals with sensitive health information, the issue of privacy is a big concern. The startup has been quick to point out that users will be fully in control of what information is shared and with whom. This means that family members can set their own boundaries, ensuring that there is transparency without having to compromise trust. While the technical measures that will be put in place to ensure privacy have not been fully outlined, the company has been quick to point out that privacy and consent are core to the product, not an add-on.
At the moment, Luffu is not yet widely available to the general public. The company has launched a waitlist for a public beta, which will allow early adopters to try out the service and give feedback before a wider launch. For families that are managing care across generations and geographies, the vision that Luffu has may sound very appealing, particularly given the shift that is taking place in the healthcare industry from individual tracking to more collaborative experiences.
Whether Luffu can deliver on its promise remains to be seen, but with experienced founders, a clear personal motivation, and a growing need for smarter family health tools, it is a startup worth watching closely in the evolving health-tech space.
