Focusing on the Sense 2 model, it introduces a new Body Response sensor that continuously tracks what Fitbit calls electrodermal activity (EDA). In a nutshell, cEDA data is combined with heart rate, pulse variation, and skin temperature data to assess body stress levels at any given time. Once the sensor does its job, the Body Response notification will guide users through activities like breathing and mindfulness sessions to alleviate stress levels.
Temperature sensing has also made its way to the Samsung Galaxy Watch 5 and is heavily rumored to appear on the Apple Watch Series 8, as well. Another notable change is that the solid-state side button on the previous-gen Sense that vibrated based on the specific touch response is gone. The indented button was quite finicky and users lambasted it for the unreliable experience.
Instead, Fitbit has resurrected the physical button for both the Sense 2 and Versa 4. In doing so, Fitbit also bonded the metal electrodes of the sensing array with the display glass, thanks to a new technique that is said to turn metal into vapor inside the chamber. The Sense 2 will hit the shelves priced at $299.99 and is now up for pre-orders from the Fitbit.com website. Custom leather bands are also available priced at $54.95, but you can also choose from less expensive options like sports and vegan leather bands.
