The Inspire 3, Versa 4, and Sense 2 are three new fitness trackers that Fitbit has made available.
The three gadgets, which are all upgrades to older models, range in sophistication from the most feature-rich to the most simple Fitbit fitness trackers.
Fitness trackers vary in how basic they are because they are all advancing toward full-fledged wristwatch capability. The entry-level tracker can already receive phone alerts like texts, calls, and app notifications, but the Inspire 3 enhances that with sleep blood oxygen monitoring and a full-color AMOLED touchscreen. Battery life predictions are reduced from 10 days to only three when the display is set to the optional “always on” mode, which is significantly less than Fitbit’s Sense and Versa watches but considerably more in line with full-featured smartwatches.
The Versa 4 and Sense 2 are Fitbit’s two most powerful trackers, in contrast. They both have battery life ratings of around six days (without the always-on display enabled) and now come with fast-charging technology, which according to Fitbit can give you a day’s worth of battery life in just 12 minutes.
With ECG sensors for Atrial Fibrillation (AFib) detection, EDA (electrodermal activity) for stress measurement, GPS, blood oxygen and heart rate tracking, the Sense 2 sits atop the Fitbit family. All of these were also features of the earlier Fitbit Sense. The Sense 2, however, expands on this by introducing new hardware and software for continuous (and hence more beneficial) AFib and stress monitoring.
The new technology, which Fitbit refers to as a “Body Response” sensor, will track your stress levels throughout the day and notify you when you’re feeling stressed. You’ll receive suggestions for guided breathing or meditation activities that you may perform on-wrist or in the Fitbit app if it detects stress.
According to Fitbit, the Sense 2 can take on-demand EDA readings right through the display using a method that transforms metal into vapor and permits the integration of the metal electrodes of the sensors “directly into the display glass of the device.” Sounds high-tech, but all it really entails is a bezel without the ring surrounding it for EDA readings that is significantly smaller.
Since 2020, when Fitbit initiated a cardiac research focused on detecting AFib, the new algorithm for continuous AFib monitoring has been under development in some capacity. The business demonstrated that its algorithm could identify 98 percent of AFib instances in a sample size of more than 450,000 people before making its way to the new Sense 2.
The Sense 2, Sense, Versa 4, Versa 3, Versa 2, Inspire 3, Inspire 2, Charge 5, Charge 4, and Luxe trackers may detect passive AFib. However, it only functions when the user is asleep. Utilizing photoplethysmography (PPG), it can identify variations in blood volume (and consequently cardiac rhythm) that could be symptoms of atrial fibrillation (AFib). Along with it, the spot-check AFib sensor from the previous Sense generation is still a part of the Sense.
Spot checks necessitate that users remain seated and cover the display with their palm, whereas passive monitoring does not. The sensor and PPG algorithm have both received approval from the US Food and Drug Administration and CE markings, demonstrating that they have satisfied the safety, health, and environmental protection standards of both the US and the EU.
There is no additional hardware added to the Versa 4 over the Versa 3, hence the Body Response sensor is absent. Instead, it had a minor physical upgrade that made it a little lighter and thinner while also reintroducing the physical button for a more dependable use.
Instead of the static settings of the past, the Sense 2 and Versa 4 now also feature customized data tiles in the UI. According to Fitbit, Google Maps and Wallet will also be available on these devices “in the coming months.”
Preorders for all three devices are now being accepted. Retail prices for the Versa 4 are $230 ($30 more than the Versa 3’s debut price), the Sense 2 is $300 ($50 more than its predecessor), and the Inspire 3 is $100 (equal to the Inspire 2’s launch price).
