Fitbit (Charge / Sense / Versa)

Fitbit (the Charge 6 band, plus the Sense 2 and Versa 4 watches; founded 2007 by James Park and Eric Friedman, acquired by Google in a deal that closed January 2021 for about $2.1B) is the budget-tier cleared anchor of the biometric cohort. The Charge 6, at about $160, brings cleared AFib/ECG (via electrodes on the Sense line), optical heart rate, SpO2, skin temperature, a Sleep Score and Sleep Profile, a Daily Readiness Score, and stress management, with an optional Fitbit Premium subscription (~$9.99/month). It is a Google product line, recorded in the registry as a distinct entity from the Pixel Watch and the Google company, and its health stack shares lineage with the Pixel Watch's Fitbit/Google Health algorithms. The throughline: the strongest cardiologist-validation gradient available at a budget price point, with the AI augmenting genuine biometric sensing.
