The AI-powered family health app developed by Fitbit founders
James Park and Eric Friedman, co-founders of Fitbit, recently introduced Luffu, a new AI-powered software that tracks health data for the whole family, including the dog's veterinarian appointment, the elderly parents' prescriptions, and the children's vital signs.

The specifics:

When something seems strange, Luffu's AI alerts consumers by compiling medical data that is normally dispersed across applications, doctor portals, and paper records.

The program allows users to enter updates via text, voice memos, or photographs and supports natural language inquiries regarding the health of family members.

A public beta waitlist is currently open, and the two are self-funding the project with a team of about 40 people, primarily drawn from former Fitbit and Google teams.

Although the app presently connects to platforms like Apple Health and Fitbit, dedicated health gadgets are planned in the future.

Over the past year, the field of AI health has grown rapidly, yet nearly everything is designed with a single user in mind. Given the rise in caregiving duties around the globe, a family-first strategy from the group that popularized personal health tracking is a gamble worth taking, particularly as AI wearables advance in sophistication.
