Fitbit Sense 2 is a good health watch with better stress tracking, but it dropped music storage and third-party apps, so it's a weak smartwatch.

What we like about Fitbit Sense 2

  • Excellent battery life (up to 6 days) compared to Apple and Pixel watches
  • Slim, lightweight, and comfortable design for 24/7 wear
  • Physical side button replaces the frustrating capacitive button from the original Sense
  • Comprehensive health sensors (ECG, cEDA for all-day stress, skin temperature)
  • Top-tier sleep tracking with detailed metrics like sleep animal profiles (via Premium)
  • Vibrant and responsive AMOLED touchscreen with improved lag over previous models

What we don't like about Fitbit Sense 2

  • Removal of third-party app support and music controls (no Spotify/Deezer integration)
  • No Google Assistant support, leaving only Amazon Alexa as a voice option
  • Slow interface and occasional UI sluggishness when scrolling or loading apps
  • Many advanced health insights are locked behind a paid Fitbit Premium subscription
  • Disabled Wi-Fi (even though hardware is present) makes software updates very slow
  • Patchy heart rate and GPS accuracy during intense, short-duration workouts

Verdict

The Fitbit Sense 2 is a health-focused smartwatch featuring a 1.58-inch AMOLED display, a lightweight aluminum case (40.5mm), and a physical side button for improved navigation. It is equipped with advanced sensors including a continuous electrodermal activity (cEDA) sensor for all-day stress tracking, an ECG app for heart rhythm assessment, and an SpO2 sensor for blood oxygen monitoring. Key pros include a robust 6-day battery life (with fast charging), highly accurate sleep tracking, and a slimmer, more comfortable design compared to its predecessor. However, main cons include the removal of third-party app support, lack of on-device music storage or control, and several advanced metrics being locked behind a Fitbit Premium subscription.
