What Happens When I Receive A Heart
When your Fitbit device detects your heart rate goes above or below your personal heart rate threshold while youre inactive, you receive a notification on your Fitbit device. Tap Open, and then tap the notification in the Fitbit app to learn more about your data and complete a survey where you log any potential factors, medications, and symptoms. You can use the info you log in the survey to track your heart health trends and share it with your healthcare provider.
Ways Continuous Heart Rate Tracking Gets You Closer To Your Goals
In the past, knowing how fast your heart was beating involved wearing an uncomfortable chest strap. But now, continuous heart rate tracking is available on a variety of wrist-based Fitbit devices thanks to PurePulse Technology. That means whenever youre wearing your compatible Fitbit tracker or smartwatch, your pulse is automatically tracked 24 hours a day, seven days a week.
You may think thats just a cool perk, but continuous heart rate monitoring is actually integral to many of the other functions your device performs. From sleep stages to calorie-burn tracking, using a device with 24/7 heart rate tracking can help you get a leg up on your health and fitness goals. Heres how:
Goal: Weight LossTry This Heart-Rate Powered Feature: Calories burned
How it helps: Anyone who wants to drop pounds knows its all about the calorie deficit: Your body needs to burn off more calories than youre taking in. Gauging how much you eat is relatively easy but knowing how many calories you burn? Because the body burns more calories at higher heart rates, thats a bit more difficultunless you have access to continuous heart rate monitoring.
To estimate your calories burned, Fitbit takes into account your basal metabolic rate , activity recorded by your tracker, and any activities you manually log. Together, this data helps your device better estimate your daily calorie burn. Give it a shot: 3 Stair Climber Workouts to Help You Get Fit, Fast.

How Easy Are They To Charge
Both the Fitbit Charge 3 and the Charge 4 use a similar clip-on charger that attaches to the back of the watch face and powers up the device. It is simple to attach and is secure so you do not need to worry about it coming detached during the charging time.
You will know that the devices are charging as a battery symbol will show on the face when the charger is initially connected. The battery life on the Fitbit Charge is up to seven days, whereas the battery on the Fitbit Charge 4 is just four days. The reason for the difference is the introduction of GPS on the Charge 4. However, both devices charge quickly, meaning you do not need to be without them on your wrist for long!
Fitbit Vs Jawbone Accuracy
According to the Human Performance Laboratory paper, the Fitbit Flex is more accurate at counting steps than the Jawbone UP24. When compared to manual step counting, the Fitbit came within 10% of the actual number of steps that the research subjects took. On the other hand, the Jawbone UP24 underestimated steps by as much as 34%.

Does Heart Rate Even Matter
The truth is, however, most people dont need the Alta HR, or any other wearable, to be quite that exact, experts say.
Knowing your precise heart rate during workouts is probably most useful if you fall into one of two camps: You have a heart condition, or youre a hardcore athlete. In the first case, youd want to avoid pushing yourself beyond your safety zone, and in the other, youd want to make sure your heart was pumping at a high-enough intensity to adequately prepare for, say, a marathon.
Otherwise, if youre young and healthy, you dont need to know your heart rate, Marc Gillinov, a cardiac surgeon at the Cleveland Clinic in Ohio, told BuzzFeed News. You might find it interesting its not bad to know your heart rate but it has no likely health benefits to you or me.
That said, experts say a strong indicator of your heart health is your average resting heart rate, which is the number of times your heart beats per minute when its at rest . And the Alta HR, in our experience, handles this just fine.
If someone measures your resting heart rate as 110, thats probably indicative that something is not good, Gillinov said. Alternatively, if you measure your resting heart rate as 60, its probably good news.
Vo2 Max For Serious Fitness Data
While VO2 Max – the metric which essentially calculates the maximum amount of oxygen that an individual can utilise during intense exercise – has made its way onto a large number of sports watches and even hearables, Fitbit has a different name for it – Cardio Fitness Score.
To access your score, simply head to the heart rate section of the Fitbit app and swipe the graph across. The higher your score, the better your fitness, and Fitbit will help determine where you sit on the scale by looking at your age, gender and resting heart rate. For more on understand the metric, read our VO2 Max guide.

Sensors As Accurate As Ever
Like other fitness trackers in this price range, the Charge 2 uses an accelerometer to record distance. During a walk, it measured 500 steps as 462, which is a bit less accurate than other fitness trackers, but not appreciably so.
I also took the Charge 2 on a 3-mile run, while wearing the Garmin Forerunner 235 GPS running watch on my other wrist. Here, the Fitbit overcounted my distance, giving me credit for having run 3.34 miles. The same thing happened on a second run, but this isn’t too unusual for accelerometer-only fitness trackers. Fortunately, Fitbit allows you to fine-tune the Charge 2 by manually inputting your stride length. Still, if you want to precisely measure how far you’ve run, you’re going to need a GPS watch, as we outline in our guide to using tech to run a 5K.
The Charge 2’s heart rate monitor proved more accurate. On my run, it measured my average heart rate at 150 beats per minute, with a max of 181 bpm. That’s pretty much in line with the Forerunner 235 , which measured my average heart rate at 154 beats per minute, and a max of 182.
Fitbit made a few tweaks to its already great app to make your data more accessible, and more user friendly.

Fitbit Charge 3 Or Charge 4
As one of the worlds biggest makers of fitness trackers, Fitbit is always under pressure to deliver new and innovative options for consumers. The Fitbit Charge 3 has been a highly successful device for the company. And, if you own one, you will appreciate the number of features you can use to ensure that your health and wellbeing take center stage.
However, you may be wondering if it is time to upgrade. Rather than being uncertain, we have the answers to your questions so that you can make your decision with confidence!
Fitbit Accuracy For Sleep Tracking
Fitbits track your sleep based on your movement at night. If you dont move at all, your tracker assumes youve fallen asleep. If you move without taking any steps, it assumes that youre restless. And if you are walking around, it assumes that youre awake.
There are three interesting facts to consider when judging Fitbits sleep tracking function.
First, the accuracy of Fitbits sleep tracking was studied in 2012, and the results are not positive. The study found that the Fitbit was frequently innaccurate. It often said that the research subjects were awake when they were actually asleep, and therefore overestimated sleep duration and quality. Second, Fitbit is the subject of a class action lawsuit, first filed in 2015, that claims that the sleep tracking function doesnt perform as advertised. Fitbit says that this lawsuit is without merit. Third, Fitbit received help earlier this year from sleep scientists from Stanford, Johns Hopkins, and the University of Arizona in order to improve the accuracy of sleep tracking.
Step Tracking Accuracy Verdict: Its difficult to say. Fitbit has revamped its sleep tracking feature since the 2012 study and the 2015 lawsuit. Its possible the upgrades have improved the feature and erased previous flaws, but the new version hasnt yet been independently tested.

Beefed Up Notifications And Exercise Tracking
Smartphone notifications have been beefed up on the Charge 2. As before, you get call and text notifications, but now the watch will show calendar events, too. That’s still more limited than the vivosmart which also shows Facebook and Twitter, as well as the weather but the Charge 2’s screen at least gives a bit more info at a glance than before.
If you use the Charge 2 in connection with your Android or iPhone while running, it can tap into the smartphone’s GPS to give you a more accurate distance and pace measurement. This is a nice feature, but if you’re already carrying your phone, there’s no real reason to also have a separate fitness tracker.
Fitbit has expanded activity tracking to include running, weights, treadmill, workout, elliptical, bike and interval training. However, unlike the vivosmart HR, which will automatically increase your steps target based on the number of steps you take each day, the Charge 2 will keep your goal at the same number until you change it yourself.
Another feature missing from the Charge 2 that’s included on the vivosmart HR is the ability to control music from the band. This is a really handy feature if you like to run with an iPod.
Fitness Trackers ‘overestimate’ Calorie Burning
Popular brands of fitness trackers can overestimate the number of calories burned while walking by more than 50%, tests have found.
Researchers at Aberystwyth University found all products – ranging from £20 to £80 in price – were inaccurate during walking and running tests.
Dr Rhys Thatcher said devices had an “inherent tendency” to over-measure.
Fitbit said its product was based on “extensive research”, but others said theirs were “not medical devices”.
The tests, carried out for the BBC X-Ray programme, measured the amount of oxygen a volunteer used during ten minute walking and running sessions on a treadmill, before comparing it to the various fitness trackers.
The Fitbit Charge 2, which is the best selling fitness tracker on the market, was very accurate in testing calories burned while running, underestimating by 4%. But when measuring walking, it overestimated by more than 50%.
Cheaper devices – the Letscom HR and the Letsfit – underestimated the number of calories burned while running by 33% and 40% respectively.
But both were far more accurate in the walking test. The Letscom overestimated by 15.7% while the Letsfit was only 2% above the official measurement.
“If you want to know the exact number of calories that you are burning during an exercise session then it doesn’t matter which device you use, you have to interpret the data with some caution,” Dr Thatcher said.

Fitbit Heart Rate Zones
Heart rate zones are essentially groupings, which allow you to adjust the intensity of your training based upon how long you spend in certain stages.
When you set up a Fitbit account you’ll be assigned your maximum heart rate, which is configured by the usual method 220 BPM minus your age and from there your heart rate zones are also established.
How Does Fitbit Measure Heart Rate
Similar to how we covered the tech for the Apple Watch heart rate monitor, let’s give a quick breakdown to how pretty much all wrist-based heart rate monitoring works.
Photoplethysmography essentially works upon one simple premise: blood is red because it reflects red light and absorbs green light. So by using green LEDs and pairing them with photodiodes, Fitbit uses its own in-house PurePulse technology to detect the amount of blood flowing through the wrist.
When your heart beats, this flow, and as a result the green light being absorbed is greater. These lights are then flashed hundreds of times per second in order to gain the most accurate BPM data.
Naturally, while every company dabbling with this optical sensor technology is working from the same blueprint, the accuracy of the readings will come down to how each company’s algorithms interpret the data.
