Fitbit Blaze: The New Face of Smartwatches

The Blaze is the newest smart fitness watch on the market and “smart” is the key word when describing it. From a bold, fashion-forward look to never before seen technological features, the Blaze is the quintessential workout companion for fitness and fashion-minded people.

It was designed to make exercise not just easier, but a priority and it accomplishes all that and more. If you want or need to lose weight this is the device for you.

While it has enhanced smart notifications, its real merit comes from the way it makes you focus on fitness. In addition to 24/7 tracking and sleep monitoring, the Blaze has the following features and benefits:

Design: Sporting a first-ever color touchscreen, the Blaze has multiple bands, including leather and stainless-steel, putting it on par with Misfit, Apple and other stylish devices.

Pure Pulse Technology: The Blaze has Pure Pulse technology to track heart rate when active and resting, but they’ve improved the sensors for more accurate readings, which is great for anyone monitoring their health or serious about fitness.

Using optical sensors, it continually tracks heart rate when moving and idle. As a result, you can see with pinpoint accuracy your overall cardiovascular health, for enhanced performance numbers that reflect your movements.

Smart Track: This is one of the Blaze’s best features and it’s quite impressive. Smart Track is an exercise recognition feature, so your device can record your activities even if you are not logged in.

It automatically recognizes activities (running, hiking, basketball, soccer, and tennis) and records according to movements for those activities. This is great if you tend to forget to program your device or don’t want to be hassled with always having to.

FitStar App: The FitStar app is a cool, new feature, one that turns your device into a personal coach. The FitStar app is built right into your device, which means you don’t need a phone or any other device to access it.

The app gives you on-screen access to 3 different sets of exercises and instructions on how to perform them. This is a big plus for beginners or those who need a push because it helps motivate you and keep you on track. It’s like having a trainer right on your wrist- so there’s no reason not to get in-shape.

Enhanced Idle Alert: in addition to all these new add-ons Fitbit also improved many of their standard features, like idle alert. The new and improved idle alert really helps to make you active and get you moving all day long.

Before, you would get a silent buzz to move after a set amount of time of being inactive and just had to get up and walk a few steps. Now, the Blaze quietly alerts you every hour until you move- and will keep buzzing until you walk at least 250 steps. This is great and makes it easier than ever for you to get in your daily activity.

Smart Notifications Upgrade: while the Blaze has text and phone notifications, it also has a way to silence them- just one more way of helping you concentrate on your workout. With this feature you can be notified of incoming calls when you need to and exercise without interruption when you don’t.

This feature works well for moms and dads who need to exercise and keep close for their kids.

Plus you can remote control your music player on your phone. How cool is it when you work out along with your favorite music?

The Fitbit Charge 2 versus Blaze: What They Have in Common

The Charge 2 and the Blaze are 2 very different devices in terms of looks, but they do share some features that can make a difference in deciding between the two. Let’s review what they have in common:

• Both provide you with Pure Pulse technology so you can monitor heart rate day and night. The Blaze’s is a bit more advanced, but they both get the deal done.

See Best Price
Each has Smart Track, so you can automatically track various exercise routines like Walking, Cardio, Biking etc, ideal for anyone who wants real-time stats that are more accurate than other devices.

• Each has the ability to show you the steps statics, and send you notifications when you get incoming calls, but the Blaze gives you the added choice of turning it off, so no interruptions when you’re getting in your work out.

• The Blaze and Charge 2 do not have GPS, but they can be synced with the GPS on your phone. Although carrying your phone can be a bit of a bother, for serious runners it makes the Surge a viable option.

The Key Differences between Blaze and The Charge 2

Now that you see how similar they are, let’s compare their differences in key areas:

Design and Look-and-Feel

The Blaze has Fitbit’s signature elastomer band and a slim, octagon shaped frame, and rectangle color touchscreen. The device also has several other colored bands as well as leather and stainless-steel bands, perfect for a night out. The screen is clear and vibrant for easy reading and it has a stylish overall look.

The Charge 2 has several colored bands for exchange and an OLED screen with minimal glare. The bands are comfortable and move with your wrist, so they are easy to wear around the clock.

Both are adjustable and can be fitted to your wrist.

For design, the Blaze has the edge. The color screen and multiple bands allow it to be worn in more settings.

Core Features

The Blaze has several great features, most notably the FitStar app with multiple coaching modes. This gives you a wide range of exercises to choose from and makes exercise accessible and more approachable. Combined with the enhanced Pure Pulse and idle alert, it really makes a difference when it comes to weight loss.

The Charge 2 has sleep and heart monitoring, for accuracy when exercising. However, it lacks the extra motivating features of the built-in FitStar app to make you move.

In this area, we like the Blaze, as the coaching features and added alerts are essential to helping you lose weight.


The Blaze’s battery can last for up to 5 days on a single charge, while the Charge 2 lasts up to 5 days. So, it’s a tie here.

Water Resistant

Both the Blaze and Charge 2 are water-resistant, but not water-proof. So you can wear them when you are exercising, but not in the shower or pool.


The Blaze comes in at $199, while the HR goes for around $150, making it the more affordable option.

What To Consider When Buying an Activity & Fitness Tracker

Before you buy either device you need to think about why you need one and how you want to use it to choose the best one. Here are some things to consider:

How active are you?

If you don’t exercise much, or don’t know how to start, then you want a device that can guide you, like the Blaze.

On the other hand, if you are active and want something simple but effective you may want the Charge 2.

What exercises do you want to do?

If you like to do a lot of different activities you want a unit like the Blaze, which is made for multiple sports.

If you prefer standard exercises or working out indoors then check out the Charge 2.

Do you need a fashion piece?

If you need a tracker that can go from work to a night out look at the Blaze, which is quite versatile in that department.

If you want something classic and simple, the Charge could be a great fit.

What is your budget?

If the price is a factor you should be happy with either device, as they are both quite affordable thanks to all the Fitbit discounts currently available.

The Blaze, Charge HR vs Charge 2

For those really looking to save, you can also look at the Charge HR, the earlier version of the Charge Series. It has all the same features as the HR, minus Smart Track and continuous heart-rate. While that may not appeal to more serious-minded workout enthusiasts, at under $100 it is more than enough for everyday workouts.

When looking at the Charge 2 and the Blaze there are lots to consider. Lifestyle factors play a pivotal role, as all the bells and whistles mean nothing if they don’t fit your needs. That is why despite all the extras that come with the Blaze it is not the clear-cut winner when choosing between the 2 devices.

The Charge 2 is simple, but effective in helping you track, analyze and monitor your health and weight loss goals, making it a smart choice for those who are on a budget or not in need of added guidance. Conversely, the Blaze is ideal for those who need an extra push or want help exercising properly. It is designed with an enhanced screen, coaching guides and is also the more stylish of the two, making it a hit with fashionistas.

In the end, when it comes to the Fitbit Blaze and Charge HR comparison it all comes down to what makes you happy. Whether you want something that looks as innovative as it performs or like a no-nonsense, practical device, the choice is yours. Whichever you choose, you can be sure that you will see results, as the one thing both devices Fitbit Charge 2 or Fitbit Blaze have in common is the ability to make exercise and healthy living a staple in your life. So choose the one that’s best for you and start getting “fit”.

    Does the Charge 2 have calendar notifications? Seems like you said it, but not seeing it come through on my tracker.
    • Emery December 20, 2017 at 11:59 am
      Hi Rachell, The Charge 2 does have calendar notifications. I found this article: You may need to modify settings on your phone (there are steps for Android, iPhone, and Windows 10). If it still doesn't work, I'd definitely contact Fitbit. They are really helpful if you go through the chat feature on their site.

    My paгtner and I absolutely love your blog and find almost all оf your post's to be exactly what I'm looking for. Dߋes one offer guest writers to ᴡrite content for you pеrsonally? I wouldn't mind writing a post or elaborating on a lot of the subjects you write with regards to here. Again, awеsome bⅼоg!
  • Lee November 18, 2017 at 8:15 pm
    Does the blaze give email, or Facebook notifications?
    • Emery November 20, 2017 at 3:56 pm
      Yes, it does both! Here's some info from Fitbit about getting and viewing notifications:
  • Beka October 29, 2017 at 5:18 pm
    Are you able to view entire text messages & review again or is it once & done like the charge 2?
    • Emery October 30, 2017 at 2:58 pm
      Hi Beka, On the Blaze, you can review texts after you've already seen them. However, the Blaze stores notifications for 24 hours, then deletes them. It also only stores 30 notifications and deletes the earlier ones as new messages come in. Hope that helps!
  • Dave Blackhall August 31, 2017 at 8:55 pm
    Which fitness tracker has the best (i.e.most accurate) heart rate monitor? As I am just recovering from a heart attack, heart rate mo nitoring is very important to me.
    • Emery September 11, 2017 at 7:40 pm
      Hi Dave, I'd definitely recommend checking with you doctor to see if there's one they prefer or find to be most accurate. I've read that most HR trackers are accurate enough for users to get a sense of their heart rate, and I've also read criticism about the heart rate tracking on fitness trackers. Heart rate monitors you wear on your wrist (like Fitbits) tend to be less accurate than chest straps, too, so keep that in mind if you need an accurate reading. Having said all of that, if it's a Fitbit you're after, we've found that the Blaze and Charge 2 are pretty similar in how they monitor HR -- you'd be okay going with either of them (permitting your doc gives the go ahead, of course). We also like the TomTom Cardio trackers for HR monitoring if you want to look outside the Fitbit line!

    This review is very helpful. I am not the typical investor as I am still a teenager. Money is not a problem so much as making the right decisions. I'd like to believe the Blaze would motivate me, but I'm also known to be stubborn. I would like to lose weight before senior year so I'm looking for anything to make the battle easier.
  • Sneha Shastri May 13, 2017 at 10:34 pm
    Hi, Thanks for the info. Helped me decide what to get myself. I decided to get Fitbit Blaze which has feature that motivate me to work out more.
  • dave griff February 20, 2017 at 12:35 pm
    Hi, Thanks for the comprehensive review. Just one question. Do both watches have built in GPS or do you have to sync it to your smart phones GPS? I want to go running and be able to track my route but not have to take my phone with me. Thanks for any advice Dave
    • Ken L. February 21, 2017 at 2:14 am
      Dave, thanks for your questions. Both would need to sync with your smartphone. I believe <a href="" target="_blank" rel="nofollow">Fitbit Surge</a> and <a href="" target="_blank" rel="nofollow">Garmin Vivosmart HR+</a> are your better beat.
  • LaNetta February 7, 2017 at 6:20 pm
    thanks for the info. helped me decide what to get for my husband. was going to get the charge, thats the one i have. I think he would like the blaze better.
    • Ken L. February 9, 2017 at 5:20 pm
      I have both and either way looks great and remind me to have this Fitness healthy life-style. I love Blaze Color Screen and Charge 2 Slim and Smart.
      • Connie August 9, 2017 at 3:20 pm
        I also have both the Charge 2 and Blaze. One thing none of the comparisons seem to mention is that Blaze can also control your music which is a nice feature. I love both of these trackers for the reasons you gave - Blaze's colors and extra features vs Charge 2's slim and smart feel
