Fitbit Founders Launch AI Health Tracker for Families

The people who helped millions track their steps just launched something that could change how families manage health together.

James Park and Eric Friedman, who created Fitbit before leaving Google in 2024, unveiled Luffu this week. The new platform pulls health information from fitness trackers, Apple Health, and family members themselves into one smart dashboard that actually makes sense.

Here's what makes it different. Instead of juggling five apps to remember if your dad took his blood pressure medication or why your daughter isn't sleeping well, Luffu does the detective work for you. Family members can share updates through voice notes, texts, or photos, and AI automatically organizes everything that matters.

The system goes beyond simple tracking. You can ask Luffu specific questions like whether switching to a Mediterranean diet might help someone sleep better, or pull up a complete medication history during an emergency room visit. No more frantically scrolling through apps while a doctor waits for answers.

The AI watches for patterns too. It sends proactive alerts when medications get skipped or when certain health metrics shift in ways that could signal bigger problems developing. Think of it as having a knowledgeable health assistant who never sleeps and actually remembers everything.

Why This Inspires

Caring for family health shouldn't require a medical degree or endless spreadsheets. Luffu represents a shift toward technology that serves families instead of overwhelming them.

The platform works for everyone in your household, including pets. That means one system for tracking Grandma's heart medication, your teenager's sleep patterns, and even your dog's vet appointments.

Right now, Luffu is in private testing, but anyone can join the waitlist on their website. It launches as a mobile app first, with plans to expand into connected hardware devices that work together seamlessly.

Park and Friedman built Fitbit into a movement that got people excited about their health data. Now they're tackling something even more personal: helping families take care of each other with less stress and more confidence.
