7. FITBIT CHARGER 2 REVIEW
Ben Sin from Forbs says Fitbit is among the earliest companies to jumpstart
that trend. The San Francisco company's latest product, the Charge 2, is sort
of all-rounded middle brother of the Fitbit family of products, which
includes the smartwatch Blaze and the minimalist wristband Alta. Personally,
I find the Charge line the most useful, since I think smartwatches are
redundant (a smartphone is already in our hands 99% of our waking life so
why do I need a second product to provide "short cuts" to access
smartphone features?) and basic step-tracker bands lack in features. As a
satisfied owner of the original Fitbit Charge HR, I didn't think I'd need to
upgrade to the Charge. But after a week of using it, I'm sold. That doesn't
mean the Charge 2 offers a huge upgrade -- it does most of the same
things the original Charge HR did, but everything is a bit more fine-tuned --
for example, the Charge 2 syncs faster than the Charge HR, and it
recognizes when I've raised my arm to check the time more often to -- like a
better total package. The Charge 2's 1.5-inch OLED screen is four times
bigger (and a bit brighter) than the Charge HR's screen, allowing for a lot
more information to flow through. From step count, heart rate, distance
walked, stairs climbed, calories burned, etc., data is a lot easier to see on the

8. FITBIT CHARGER 2 REVIEW
Otherwise, the Charge 2 isn't a great departure from its original
design, aside from being slightly more slender. The elastomer strap is
comfortable to wear and since it uses a standard watch buckle,
putting it on isn’t fiddly – unlike some previous Fitbit trackers that
used difficult clasps. I didn't encounter any discomfort with it on,
even when I became particularly sweaty during a run says a reviewer
Richard Easton on trusted reviews..

12. GARMIN VIVOFIT 2 REVIEW
A neat little fitness tracker whose battery life and waterproofing
means you never need to take off. And if it were just that bit more
useful and more comfortable, you would never want to take it off
either. Still, a solid effort for the price. This doesn't have to be
accurate to NASA standards, but if I've spent the day walking around
Paris I want the graph to be more virile than if I've spent the day in
bed (both done for the good of this review). And with these
parameters set, the Vivofit 2 delivered; the screen is big and bright, it
can survive in the drink and it doesn't need charging. This is
from Rob Temple on the website TechRadar.

13. GARMIN VIVOFIT 2 REVIEW
Get up and get moving with vívofit 2. It’s the only activity tracker with
a 1+ year battery life and backlit display. It even reminds you to stay
active throughout your day with its move bar with audible alert that
lets you know when you’ve been idle for an hour or longer this comes
from the Garmin website.

19. SAMSUNG GEAR FIT 2 REVIEW
The Fit 2 is more than just a fitness tracker. It's a sort of like a mini
fitness smartwatch. There are a variety of appealing watch faces to
choose from, you can view and respond to notifications from your
Android phone right on your wrist, and there's a built-in Spotify app.
The Fit 2 is like a slimmed-down version of Samsung's Gear S2
smartwatch. It has the same fitness features and notifications (and
those features are both very good), but it's missing app support.
There are some basic apps, like a stopwatch and a timer. The one to
care about is the Spotify app, which lets you control and access your
playlists right from your wrist. Unfortunately, you still need a phone
connected to use it.

20. SAMSUNG GEAR FIT 2 REVIEW
According to a reviewer on cnet Samsung got my attention with the
Gear Fit 2. It had everything I looked for in a fitness tracker: all-day
fitness tracking, heart rate, GPS for tracking pace and distance when
running, smartphone notifications, inactivity alerts and automatic
exercise detection. It even had some features I never even thought I
would use, such as onboard music storage, and water and caffeine
tacking.
