Why buy each?

Apple Watch

Heart rate every five seconds

The new health sensing system samples heart rate every five seconds all day — 60x more often than the Series 11 — and measures HRV every five minutes.

Readiness score

A daily 0–10 readiness score combines sleep, vitals, training load, and activity to suggest how hard to push.

ECG, SpO2 and hypertension notifications

On-demand ECG, blood oxygen monitoring, sleep apnea detection, and hypertension notifications carry over from the Series 11.

Fitbit Sense

Continuous EDA stress tracking

The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.

6 months Fitbit Premium included

Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.

6-day battery, works with iPhone

Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.
