Google-owned business chose to discreetly tweak the Versa 4 and Sense 2 designs this year. Except for the hardware button that replaced the capacitive one

On the inside, the theme is pretty much the same. Unlike its predecessor, the Sense 2's new continuous EDA sensor helps manage stress all day long

This can help you recognise possible stress triggers and come up with a plan for dealing with stress that will make you stronger over time

Along with the Versa 4, it offers 40 exercise modes (twice the previous number), GPS, and over 1,000 workouts and mindfulness sessions

It gives exact sleep tracking and the Daily Readiness Score, which tells you "whether to push hard or take a break day." Fitbit won't cancel its premium subscription

None of these devices run Wear OS because they were in development when Google bought Fitbit. Google promises Maps and Wallet apps for the Versa 4 and Sense 2

These two have 24/7 heart rate monitoring, real-time information, and "over six days of battery life." Fast charging gives one day of power in 12 minutes

Fitbit's entry-level tracker, the Inspire 3, captures activities, heart rate, calories, distance, sleep, and stress in a redesigned tiny, light, and colourful compact

Depending on how you use it, it can last up to 10 days on a single charge and at least 3 days with the always-on display function

The Versa 4 is $229.95, the Sense 2 is $299.95, and the Inspire 3 is $99.95. In all cases, you get a free six-month Premium membership that automatically renews

All three models can be pre-ordered at fitbit.com and "select global retailers." The Inspire 3 will be available in September, and the other two will come "this fall."
