If you’re part of the “sandwich generation,” you’re juggling more than just your own life.
You’re tracking your parents’ medications, booking doctor appointments, checking in on symptoms, coordinating with siblings and somehow trying to stay on top of your own health too.
Keeping your family healthy feels like a full-time, unpaid job.
It’s messy. Fragmented. And often, overwhelming.
A dozen apps. Multiple hospital portals. Endless WhatsApp messages. And underlying all of it is a constant, quiet anxiety: Is everyone okay when I’m not there?
That’s exactly the problem the founders of Fitbit are now trying to solve with their new venture Luffu (“loo-foo”).
From tracking steps to tracking people you love
After building one of the world’s most successful personal health tracking companies, James Park and Eric Friedman are building something more meaningful.
While Fitbit revolutionised personal health metrics, Luffu is built on the premise that health is a shared experience.
As Park puts it, we’ve built plenty of tools to track our own steps, sleep, and workouts. But when it comes to managing the health of the people we care about most, the system completely breaks down.
“There’s almost nothing to help you track the people you love most in a way that feels seamless and supportive, not invasive.”
Luffu is here to fix that, and it’s born out of the founder’s own experiences.
After selling Fitbit to Google, the duo turned their attention to a growing reality: millions of people are simultaneously caring for ageing parents and growing children.
They didn’t want to build another app. Rather, build a central nervous system for family health.
As Park describes it,
“We want to take the ‘work’ out of caregiving. Luffu is meant to be the ‘guardian’ that watches over them when you can’t be there.”
So, how does Luffu actually work?
Luffu is an “intelligent family care system.” It functions by quietly gathering and organising health data in the background to learn a family’s unique rhythms. It connects the dots you didn’t know existed.
Here’s what that looks like in practice:
- Guardian moments
Luffu continuously monitors patterns and surfaces meaningful alerts, so you’re notified when something actually matters, not for every small data point.
- Effortless logging
No more manual tracking headaches. Users can log medications, symptoms, meals, or doctor visits using voice, text, or even photos.
- Data integration
It pulls in data from wearables, health portals, and other sources, bringing everything into one place.
- Family care circles
Everyone involved, parents, partners, caregivers, stays in sync through a shared view, without constant check-ins or updates.
The goal is simple: less coordination, more clarity.
AI that works quietly in the background
Unlike typical health apps that rely on reactive prompts, Luffu uses AI as an invisible layer that notices.
Learning your family’s routines and patterns over time, it surfaces early signals before those small issues become bigger problems.
Of course, with something this sensitive, privacy becomes a big concern.
Luffu leans heavily into a “privacy by design” approach, giving users full control over what gets shared and with whom.
Still early, but a familiar playbook
As of its February 2026 announcement, Luffu is in its early stages.
There are currently no clinical trials or validated health outcomes. The company is positioning itself not as a diagnostic tool, but as a coordination and peace-of-mind layer.
But the founders bring serious credibility. Their proven track record with Fitbit, which scales to nearly 150 million users, is something the founders are trying to replicate. But this time, to families.
When’s Luffu going to launch?
Luffu’s rollout will be gradual:
- Limited public beta: The company is currently accepting sign-ups for a limited public beta via its website.
- App-first strategy: The initial launch focuses on the software experience for caregivers.
- Hardware Expansion: The long-term vision includes developing an ecosystem of first-party hardware devices designed to complement the app and provide more comprehensive family monitoring.
Wrapping up
For years, health tech has focused on the individual.
Your steps. Your sleep. Your vitals.
But real life doesn’t work that way.
Health is shared. It’s coordinated. It’s emotional. And often, it’s managed collectively by families.
Luffu is built around that reality.
And if the founders’ track record is any indication, this “loo-foo” might just become the new language of family care.
