Fitbit Sense 2 Smartwatch helps people worried about sleep, stress and heart rhythm stay informed and calmer.

⚡ At a Glance
- • Wearing Comfort: Sleek, slim profile with small and large straps included for comfortable all-day wear
- • Best for: Health-conscious users who want continuous stress, sleep and cardiac monitoring
- • Not ideal for: Users who need a standalone cellular watch with integrated mobile network connectivity
Designed for comprehensive on-wrist health tracking with built-in GPS and multiple physiological sensors. Battery life exceeds six days while water resistance to 50 metres supports swim workouts and daily wear.
Clinical-style heart and stress monitoring - with cEDA, ECG and irregular rhythm alerts
Continuous electrodermal activity measurement, called cEDA, gauges stress by tracking subtle skin conductance changes, while the ECG app performs atrial fibrillation assessment and irregular heart rhythm notifications monitor atypical patterns. SpO2 sensing and a health metrics dashboard aggregate those signals for clearer trends.
Early spotting of worrying trends and a daily Stress Management Score help users decide when to rest or seek medical advice. Clear notifications keep users informed without constant checking.
Deeper sleep insights - with personalised Sleep Profile, Sleep Stages and Smart Wake
A personalised Sleep Profile compares ongoing sleep data to typical patterns and breaks sleep into stages, producing a Sleep Score and tailored guidance. Smart Wake uses sleep stage timing to suggest optimal alarm windows.
Actionable sleep feedback helps fine-tune bedtime and recovery routines, making small behavioural changes easier to spot. Morning wake choices can feel less jarring thanks to stage-aware alarms.
All-day tracking and swim-ready durability - thanks to 6+ day battery and 50 metre water resistance
Battery performance supports more than six days between charges with fast-charge capability to reduce downtime, while water resistance to 50 metres allows use during swimming and showers. Two strap sizes are supplied for a secure fit across wrist sizes.
Long stretches of continuous monitoring reduce the need to remove the watch for charging, preserving data continuity. Swim sessions and everyday wear are covered without frequent maintenance.
