Fitbit Charge HR已经推出几个月了，所以这篇评论对你来说可能是旧消息。但是，我们敢打赌，我们的评论将脱颖而出，因为它是基于几个月的日常使用该设备的经验得出的。如果您想了解它的工作原理，它是否可以帮助您改善健康状况(health and wellbeing)，以及它是否是一种在佩戴时不会引起任何奇怪皮疹和健康问题的设备，那么您应该先阅读这篇评论购买Fitbit Charge HR。有很多地方需要覆盖，所以让我们开始吧：
拆箱 Fitbit Charge HR
Fitbit Charge HR使用的包装与其他Fitbit设备的包装非常相似。您可以轻松查看设备及其最重要的规格。
在包装盒的背面，您可以找到有关其所有主要功能的更多详细信息，并提供多种语言版本。
打开包装盒后，您会发现Fitbit Charge HR、无线同步加密狗(wireless sync dongle)、充电线、保修和快速设置指南(setup guide)。
现在您已经了解了该设备的外观，让我们来看看它在规格方面提供的功能：
硬件规格
首先(First)，Fitbit Charge HR提供三种尺寸：小号、大号和超大号。为了正确选择适合您的尺寸，您应该阅读本指南(this guide)。该设备具有一定程度的防水(water resistance)功能，但只能吸收少量的水，例如汗水、雨水和水溅(rain and water splashes)。你不能戴着它游泳、洗澡或洗碗。您必须在此类活动期间将其取下。
在传感器方面，Fitbit Charge HR包含一个光学心率监测器(heart rate monitor)、一个 3 轴加速度计、一个高度计和一个振动电机(vibration motor)。
腕带由类似于许多运动手表中使用的柔性弹性体材料制成。(elastomer material)Charge HR 还有一个外科级不锈钢扣(stainless steel buckle)。该设备有五种颜色可供选择：黑色、蓝色、李子色、橘色和蓝绿色(tangerine and teal)。不幸的是，Fitbit仅提供其中四种颜色的图片，如下所示。
该设备有一个简单的OLED 显示屏(OLED display)，您可以通过点击它或按下其左侧的按钮来打开它。承诺的电池寿命(battery life)长达 5 天，充电时间为一到两个小时。为了给它充电，您必须使用包装中包含的充电电缆。您不能使用其他任何东西进行充电，因为该设备有自己的专有电源插孔(power jack)。
为了向其他设备发送和接收数据，Fitbit Charge HR具有蓝牙 4.0(Bluetooth 4.0) 无线电收发器(radio transceiver)。在内存方面，该设备可以跟踪多达 7 天的详细运动数据、多达 30 天的每日总计和心率数据，在(heart rate)运动跟踪(exercise tracking)期间以 1 秒为间隔，在所有其他时间以 5 秒为间隔。Fitbit Charge HR的一大亮点是其出色的设备支持(device support)。它提供适用于Windows、Android、iOS、Windows Phone 和 Mac(Windows Phone and Mac)的应用程序。但在本次审查的稍后部分会对此进行更多介绍。
您可以在此处查看完整的官方规格：Charge HR 规格(Charge HR Specifications)。
使用 Fitbit Charge HR
使用Fitbit Charge HR唯一复杂的部分是设置它。首先(First)，您需要使用Fitbit创建一个帐户，然后添加您的设备并首次同步它。在继续使用它之前，最好设置您希望它的工作方式。这是使用可用的众多应用程序之一完成的。
您应该设置以下内容：您的主要目标、点击显示屏时的功能、您希望Fitbit如何跟踪您的心率(heart rate)、您佩戴设备的手腕、设备同步(device syncs)方式、您的体重、身高、您要使用的测量单位等。列表很长，我们强烈建议您花一些时间(quality time)进行设置，否则您将不会对您将获得的某些结果感到满意。
设置完成后，关闭您正在使用的Fitbit 应用程序(Fitbit app)并恢复您的正常活动。稍后，当您再次查看Fitbit时，请查看它是否根据您的喜好报告和测量事物。在获得您感兴趣的数据之前，不要犹豫，尝试许多可用的设置，尽可能精确。
对于可穿戴设备而言，非常重要的一个方面是您的皮肤对它们的耐受程度。我们很高兴地报告，在使用Fitbit Charge HR(Fitbit Charge HR)几个月后，我们没有出现皮疹和刺激问题。只要您每周清理一次设备，就应该没问题。此外，橡皮筋(rubber band)不会粘在您的手臂上，也不会留汗。
如果您想从Fitbit Charge HR获取数据，您可以使用显示屏并让它分享今天(share today)的总体数据，例如：卡路里、步数等，或者您可以使用Fitbit 应用程序(Fitbit app)并获取详细的统计数据在。我们在Windows Phone 智能手机上使用(Windows Phone smartphone)Fitbit Charge HR时遇到的一个问题是，我们无法让来电显示在Fitbit上工作。即使我们禁用了 All Day Sync也是如此。显然这些功能不能同时工作。
我们注意到的另一个小错误是，当您拍手时，例如去听音乐会时，显示屏会自动打开，Fitbit可能会在此期间计算一些步数，即使您只是在移动您的手。在我们看来，这是一个小问题。
关于您从Fitbit Charge HR获得的数据，您必须知道，无论您测量什么，它都不是 100 % accurate首先(First)，衡量你一天中的步数通常是好的。是的，如果您在音乐会期间拍手，它会测量步数，但这并不会真正以有意义的方式影响您的整体数字。您从Fitbit获得的数据足以让您了解自己的活跃程度并帮助您采取改进措施。
我们对Fitbit(Fitbit)提供的睡眠跟踪(sleep tracking)非常满意。您可以为自己设定睡眠目标，并跟踪您每晚的睡眠时间、焦虑程度等。Fitbit Charge HR帮助我们改善了每晚的睡眠时间，并让我们决定为这项“活动”留出更多时间。结果，我们每天早上都感觉更好，而且我们一整天的工作效率都更高。
在我们看来，Fitbit Charge HR的主要弱点正是让它与众不同的地方：心率监测。首先(First)，与使用身体其他部位相比，测量手腕区域的心率会导致结果的准确性降低。此外，准确性受到皮肤色素沉着、移动方式、移动量、佩戴设备的确切位置以及它在身体上的紧贴程度等因素的影响。Fitbit 甚至创建了有关如何使用该设备的指南最好的结果，你应该阅读它：心率常见问题解答(Heart rate FAQs)。
我们对它的静息心率(heart rate)测量感到满意，它显示了你静止时的心跳，它可以成为你心脏健康的重要指标。这些报告似乎与现实足够接近，并提供了对我们有用的数据。
关于承诺的电池寿命(battery life)——除非我们停止心率监测，否则我们永远无法让Fitbit Charge HR持续使用 5 天，这违背了购买(Fitbit Charge HR)Fitbit Charge HR而不是Fitbit Charge的目的。在现实生活中，您应该期望 4 天的电池续航时间(battery life)，或多或少需要几个小时。但是，充电通常很快。在大多数情况下，Fitbit Charge HR会在大约 1 小时内充电。使用几周后，我们养成了在淋浴时让它充电的习惯。通过这种方式，我们保证了它的安全，远离水，并且在我们没有采取很多步骤时它正在充电。您可能想养成类似的习惯。
用户体验(user experience)的很大一部分是您正在使用的可穿戴设备的软件生态系统。(software ecosystem)有些设备具有出色的传感器和硬件，但应用程序却很差。幸运的是， Fitbit(Fitbit)并非如此。有关此主题的更多信息，请参阅本评论的下一部分：
A long-time user's review of the Fitbit Charge HR
Fitbit Charge HR has been launched for a couple of mоnths now so this reνіew might be old news for уou. However, we bet that our review will stand out from the rest, as it is made bаsed on a couple of months of daily usage experience with this device. If you are curious to learn how well it works, if it might helр you improve your health and wellbeing, and whether it is a deviсe that wоn't cause any weird rasheѕ and health problems while wearing іt, then you should read this review before purchasing Fitbit Charge HR. There's lots of ground to cover, so let'ѕ get started:
Unboxing the Fitbit Charge HR
The packaging used for the Fitbit Charge HR is very similar to that of other Fitbit devices. You can easily see the device as well as its most important specifications.
On the back of the box you will find more details about all its major features, in several languages.
When you open the box, you will find the Fitbit Charge HR, a wireless sync dongle, the charging cable, the warranty and a quick setup guide.
Now that you got an idea of how this device looks, let's take a look at what it has to offer in terms of specifications:
Hardware Specifications
First of all, the Fitbit Charge HR comes in three sizes: small, large and extra-large. In order to correctly choose the size that fits you, you should read this guide. The device has some degree of water resistance but it can only take small quantities of water, like sweat, rain and water splashes. You can't swim with it, take a shower or wash the dishes while wearing it. You must take it off during such activities.
In terms of sensors, Fitbit Charge HR packs an optical heart rate monitor, a 3-axis accelerometer, an altimeter and a vibration motor.
The wristband is made of a flexible elastomer material similar to that used in many sports watches. Charge HR also has a surgical-grade stainless steel buckle. The device is available in five colors: black, blue, plum, tangerine and teal. Unfortunately, Fitbit offers pictures only for four of these colors, as you can see below.
The device has a simple OLED display that you can turn on by tapping on it or by pressing the button on its left. The promised battery life is up to 5 days and the charging time of one to two hours. In order to charge it, you must use the charging cable included in the package. You can't use anything else for charging because this device has its own proprietary power jack.
In order to send and receive data to other devices, Fitbit Charge HR has a Bluetooth 4.0 radio transceiver. In terms of memory, the device can track up to 7 days of detailed motion data, up to 30 days of daily totals and heart rate data at 1 second intervals during exercise tracking and at 5 second intervals all other times. One area where the Fitbit Charge HR shines is its excellent device support. It offers apps for Windows, Android, iOS, Windows Phone and Mac. But more on that later in this review.
You can view the full set of official specifications, here: Charge HR Specifications.
Using the Fitbit Charge HR
The only complicated part of using the Fitbit Charge HR is setting it up. First, you need to create an account with Fitbit, then add your device and synchronize it for the first time. Before moving forward to using it, it is a great idea to set how you want it to work. This is done using one of the many apps that are available for it.
You should set things like: your main goal, what the display does when you tap on it, how you want Fitbit to track your heart rate, on which wrist you are wearing the device, how the device syncs, your weight, height, the units of measurement that you want to use, etc. The list is long and we strongly advise you to spend some quality time setting things up, otherwise you won't be pleased with some of the results you will get.
Once you set it up, close the Fitbit app that you are using and resume your normal activities. When you check back on Fitbit, later on, see whether it reports and measures things to your liking. Don't hesitate to experiment with the many available settings until you get the data you are interested in, as precisely as possible.
One aspect that's very important about wearable devices is how well they are tolerated by your skin. We're happy to report that, after several months of using Fitbit Charge HR, we had no issues with rashes and irritations. As long as you clean up the device on a weekly basis, you should be OK. Also, the rubber band doesn't get sticky on your arm and it doesn't have the tendency to trap sweat.
If you want to get data from the Fitbit Charge HR, you can use the display and have it share today's overall numbers like: calories, steps and so on, or you can use the Fitbit app and get detailed stats of what is going on. One issue that we have experienced when using the Fitbit Charge HR with a Windows Phone smartphone is that we couldn't get the caller ID to work on the Fitbit. That's even though we disabled All Day Sync. Apparently these features don't work simultaneously.
Another small bug we noticed is that, when you clap your hands, like when going to a concert, the display turns itself on and Fitbit may count some steps during that time, even though you are moving only your hands. It's a minor quibble in our view.
Regarding the data you get from the Fitbit Charge HR, you must be aware that it is never 100% accurate, no matter what you measure. First of all, measuring the number of steps you do in a day is generally good. Yes, it measures steps if you clap your hands during a concert but that doesn't truly impact your overall numbers in a meaningful way. The data you get from Fitbit is meaningful enough for you to understand how active you are and to help you take measures for improvement.
We were very pleased with the sleep tracking offered by Fitbit. You can set sleep goals for yourself and track how much you sleep each night, how agitated you are and so on. Fitbit Charge HR has helped us a lot in improving how much we sleep each night and made us decide to allow more time for this "activity". As a result, we felt better each morning and we had better productivity throughout the day.
In our view, Fitbit Charge HR's main weakness is exactly what should set it apart: heart-rate monitoring. First of all, measuring heart-rate in the wrist area leads to less accurate results than when using other areas of your body. Also, the accuracy is hit by skin pigmentation, how you move, how much you move, where exactly you wear the device and how tight it stays on your body, etc. Fitbit has even created a guide on how to use the device for the best possible results and you should read it: Heart rate FAQs.
We were pleased though with its resting heart rate measures, which show how your heart beats when you are still, and it can be an important indicator of the health of your heart. These reports seemed close enough to reality and provided data that was useful to us.
Regarding the promised battery life - we could never get our Fitbit Charge HR to last 5 days unless we stopped its heart-rate monitoring, which defeats the purpose of buying Fitbit Charge HR instead of Fitbit Charge. In real-life you should expect 4 days of battery life, give or take a couple of hours. However, charging is generally fast. In most cases, Fitbit Charge HR charges in about 1 hour. After a couple of weeks of use, we developed the habit of leaving it to charge while we showered. This way we kept it safe, away from water and it was charging while we were not taking many steps. You might want to develop a similar habit.
A big part of the user experience is the software ecosystem of the wearable device that you are using. Some devices have great sensors and hardware but very poor apps. Luckily, this is not the case for Fitbit. More on this subject, in the next section of this review:
