Fitbit Charge 6 Vs Sense 2 – Check Which One Is Best & Why?

Fitbit Charge 6 & Sense 2 share many similarities, but there are also important differences, such as quality, performance, features & design. If you want the best one between them, I Would recommend the Fitbit Sense 2  rather than the Charge 6.

Why Do I Recommend The Fitbit Sense 2

  • The Fitbit Sense has a Larger AMOLED 1.58-inch display, which is more vibrant and offers larger visuals than the Fitbit Charge 6’s smaller display.
  • Fitbit Sence 2 has a brighter & higher resolution display, which makes it easier to read the display even in direct sunlight or other bright environments than the Fitbit Charge 6’s display.
  • It is designed for more health solutions like advanced ECG, & skin temperature tracking to monitor health conditions and track overall wellness, while the Fitbit Charge 6 lacks these advanced sensors. 
  • The Sense 2 includes the Electrodermal Activity (EDA) sensor and advanced stress management tools to track real-time body responses to stress. But the Charge 6 lacks this feature and relies on basic heart rate.
  • It features an electrocardiogram (ECG) app that can be used to assess heart rhythms and detect irregularities that are absent in the Charge 6.
  • Fitbit Sense 2 has automatic body response tracking for alerting physical & emotional stress, while the Charge 6 does not have this functionality.
  • The Fitbit Sense 2 supports voice assistants to give voice commands, set reminders, or control smart devices, which isn’t available on the Charge 6.
  • Additionally, the Fitbit Sense 2 has a more premium design & Gorilla Glass 3 for screen protection. In contrast, the Charge 6 has a standard design and lacks screen protection.

Maybe the Fitbit Charge 6 price can make you comfortable because it’s a little bit cheaper than the Fitbit Sense 2. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
