Smart wear­ables are grad­u­al­ly tak­ing over the mar­ket. Today, Fit­bit, its leader, intro­duced the new Flex 2 fit­ness track­er, which is rad­i­cal­ly dif­fer­ent from its pre­de­ces­sor.

Flex 2 is a slim fit­ness track­er that tracks laps, dura­tion and calo­ries burned. The track­er itself can detach from the strap, con­nect to anoth­er strap, or be worn around the neck as a pen­dant. It does not use a dis­play, but dai­ly achieve­ments or noti­fi­ca­tions are dis­played using five built-in LEDs.

It does not have heart rate sen­sors and GPS. Instead of the lat­ter, the Fit­bit Track intel­li­gent sys­tem is used, which auto­mat­i­cal­ly deter­mines the begin­ning of a par­tic­u­lar exer­cise. With a long “sit­ting” the bracelet begins to vibrate. In addi­tion, it works up to 50 meters under­wa­ter, and auto­mat­i­cal­ly rec­og­nizes when the wear­er is swim­ming. Flex 2 holds a charge up to 5 days.

The Fit­bit Flex 2 comes in three fin­ish­es: Gold, Sil­ver and 22K Rose Gold. The device costs $99.

Fol­low­ing Flex 2, Fit­bit intro­duced the Charge 2 fit­ness bracelet. The first dif­fer­ence from its pre­de­ces­sor is a four times larg­er dis­play, though not a touch­screen. Man­age­ment is still the same with a sin­gle phys­i­cal but­ton. The track­er menu has a sub­menu sec­tion, which can be accessed by tap­ping the screen.

In addi­tion, the bracelet has a built-in GPS mod­ule that allows you to more accu­rate­ly track the move­ment of the own­er. In con­junc­tion with the phone, he is able to dis­tin­guish between the type of move­ment: walk­ing, run­ning or cycling. At the end of the exer­cise, the result will be entered into the Fit­bit app.

The devel­op­ers have added a Car­dio Fit­ness fea­ture to the track­er that uses data on age, gen­der and weight along with the lev­el of heart rate. Based on them, the track­er sets a car­dio goal that must be achieved dai­ly.

Final­ly, the Relax func­tion appeared, which is respon­si­ble for the user’s breath­ing. It will encour­age the own­er to per­form two to five min­utes of breath­ing exer­cis­es, but some­what dif­fer­ent than in watchOS 3.0 for Apple Watch.

The price of the gad­get starts at $149. Bat­tery life on a sin­gle charge is up to 5 days. [The Verge]
