Overview W / Me2 is the first tracker to measure pressure. And also the pulse. And records an ECG

    Good morning!

    Today I will share with you my personal impressions that I received during the use of W / me2, a universal and transformable bracelet and the first gadget that I took for personal use for 4 years of work in Medgadgets.




    As a short introduction, I’ll say that I have been working in Medgadgets from the very beginning and to the envy of many of my friends, I always had unlimited access to all kinds of pieces of iron, but somehow they all returned to our shelves, because they seemed unattractive, uncomfortable, not applicable, etc.

    So W / me2 is also a milestone in my biography, as this is the first bracelet that impressed me and hung on my wrist for a long time. There are several reasons for this, and I will try to briefly tell you about each of them. I also ask you to pay attention that I write this post as a private person and do not attach it to our corporate blog on GeekTimes, although I will be forced to refer to it.

    Packing and equipment

    The first kits that we brought to Russia have an “overcomplectation”, and this will continue until special instructions from the manufacturer.

    A complete set of the first delivery looks like this:



    In the kit you will find:

    • Sensor
    • Two sets of bracelets
    • Chest strap
    • Dongle
    • Charging cable


    I want to note that W / me2 is charged with a special cable , and it cannot be recharged from standard mini / micro USB.



    Dongle mounts are universal, and it can be “stuck” on any chest belt. Here, for example, you see it on the Runtastic belt:



    For all its brevity, the large box was not as practical as we would like, and many packages were slightly wrinkled upon delivery, but this is not critical, since the box with handles is disposable, and it is practically impossible to open it without damaging it completely:



    The main features of W / me2 are briefly listed on the box, screenshots of the application are shown, the “composition” is indicated, and the specific equipment is marked with a sticker: with a T-shirt, with a top for girls, with a chest strap. The front part is transparent.



    The sensor itself is packaged separately in its box. It looks like this:



    A couple of days ago we received a teaser of a box in which a new batch of W / me2 will come. It will be a little more concise and practical when transporting:



    Everything is in its place.

    Appearance

    For me it was important how the device looked, and I definitely did not want this or that gadget to impose a wardrobe on me, to force it to hide or to veil. In this sense, W / me2 completely suited me and during the reporting time I went to two weddings in two different costumes, went to the office in CKjeans super-heavy jeans, went to the country in galoshes and boots, changed the mass of jumpers and shirts, and not one Of the cases I did not experience anything close to “don’t sew the mare’s tail”.



    Taking into account the fact that the trends in men's accessories do not change so much from season to season, I don’t think it at all necessary to bother: black with steel is always relevant. In the same year, trends on geometric and asymmetric patterns were marked on the catwalks and even more so, and Tom Ford returned the “Soviet Christmas tree” to outerwear, so everything is in order with the design. I even allowed myself to dream a little and went through the new collections of accessories.



    So, W / me2 is a gadget with a “broken” shape of a regular roof, or arrow, the front side of which is decorated with a functional circle that stands out on a common surface due to two factors. It is slightly indented and has a glossy texture, unlike the matte surface of the device.



    The black square of the display is framed on both sides by a steel case and does not light up (to save energy) constantly, and together with the bracelets forms the following composition of colors:

    • black - steel - black - steel - black
    • white - steel - white - steel - white




    The bracelets themselves have an individual fastening, and it is impossible to mix up “holes”: The



    clasp is made in the form of a steel rectangle with a logo on it.
    Silicone bracelets are decorated with thin stripes.



    Over time, bracelets change shape. Compare: the black that I wear and the white are just out of the box.



    * Note

    I am talking about a bracelet that I wear on my left hand, but there is a choice in the settings. If you are comfortable wearing accessories on your right wrist or you are wearing a watch on your left hand, you can change the location of the device. Then the only button you will have is not on the right side of the sensor wall, and not the left.



    The second remark, it seems to me, is important, which prompts you to make the design of the device: this geek-accessory does not give out to the user a person who takes special care of his health. This idea is familiar to me from the review of Lumo lift , a posture corrector, where no stranger will know that a person has any problems with his back or that he uses additional means of motivation.

    It is very ethical in relation to future owners, in my opinion. Outsiders see a stylish accessory, cool watch, and not the problems that they need to solve.

    Control

    Access to the sensor functionality is opened in a special application, but the bracelet is equipped with a button, and it also has several features. Firstly, a long retention cuts down the bracelet and restarts it, while erasing the daily statistics.

    The button also switches between six screens:

    1. Time. This screen after a brief inactivity is replaced by battery statistics. However, only a battery strip is visible, without interest.
    2. Steps
    3. Calories
    4. Distance
    5. Stopwatch
    6. Shutdown screen

    • To see the number of steps or distance, just linger for a second on the screen you need.


    At the same time, a long hold on each of the screens causes additional functions.



    1. Time. Long hold puts the bracelet in sleep tracking
    2. Steps. Long holding puts the bracelet in sleep tracking.
    3. Calories A long hold shows some numbers. Until I guessed what they mean.
    4. Distance. Long hold shows your W / me2 name
    5. Stopwatch. Long hold starts the stopwatch
    6. Shutdown - shutdown.

    • To turn on the screen and switch between them, you can use the double “tap” on the tracker or, as is realized, for example, in the Moto360, turn the wrist. However, this function is not "by default" and is enabled in the settings. At the same time, you will see a warning that it is energy intensive.





    Software

    Functions that attracted me are available using the W / me2 application:



    * Applications we Russified!

    In general, it should be noted that W / me2 is the first gadget with which we have gained such experience. The kit includes a brief Russian-language manual, where on the front page Medgadgets is presented as an official distributor.



    We continue to constantly communicate with the development team, exchanging ideas to improve the quality of the device and services. We rewrote software in our language. In general, it was cool.

    The main functions of

    Pressure

    I slightly deceived, saying that this is the first bracelet that measures pressure. Before that, we tested Healbe Gobe, where this function was also announced, but, in our opinion, Healbe showed a serious error. So for justice: W / me2 is the first bracelet that measures pressure accurately .

    For me, this function turned out to be decisive when I chose a gadget, as it seems to me that this is exactly what wearable bracelets have been missing all this time. The only thing is that the pressure is indicated in the appendix by the term from hemodynamics “SPV”, or the pulse wave propagation velocity, which, if you find fault, is not the same thing. But in the testimony this should be read precisely as pressure.



    To measure the pressure, I recommend completely exposing the gadget by removing the belts and other accessories, since W / me2 is quite sensitive to various kinds of interference. Here, for example, is what the “life line” looks like if you forget to disconnect the charging cable, and next is a screenshot of the “normal” display.



    The measurement is not in real time, and to get health data, you need to spend a little more than a minute.



    It is important to take the device with two different hands and make sure that they do not touch each other. Next, start the measurement mode and hold both contacts on the top and bottom with different fingers. As a guide: circles above and below.



    For the sake of fidelity, I try so that the fingers of one hand do not touch each other.

    • Not forget


    If you started the measurement process, but for some reason got distracted, you need to get out of it! Click back or remove the application from the processes.



    If you just close it, returning to the initial screen, the bracelet will not stop waiting for you, and this will leave you a battery:



    The

    W / me2 pulse has two modes: normal and sports. The latter starts at the moment of training in the corresponding tab, where you can select various types of activity. In this case, you simply hang the belt on your chest, fasten the sensor using a special dongle and begin to train.



    Total in the "Training" tab:

    • Bike ride
    • Run
    • Aerobics
    • Training (gym)
    • Yoga
    • Dance
    • Other (you can enter the desired type of activity)


    An inconsistent heart rate can also be measured with a strap on your chest, or by holding the tracker with two fingers. I apologize for the details:



    ECG

    Actually, both pressure, pulse, and ECG are a single process, and you cannot measure something separately. All data is displayed in a list and stored in the measurement history. The sensor takes a two-channel ECG for you, with which you can contact a cardiologist. There are enough parameters to determine the pre-infarction state. You still have the medical transcript and schedule on your hands. To go to the extended measurement window, you need to click on the "rainbow".



    Autonomic nervous system

    The sensor offers a quick analysis of your autonomic nervous system, characterizing it as sympathetic or parasympathetic and encourages you to maintain balance in it, helping you regulate your condition at this particular moment.



    A system of breathing exercises is proposed as one of the methods for improving the condition.

    Breathing exercises

    In order to understand how correctly and accurately you follow the prompts of the application, while carrying out breathing exercises you also need to hold the sensor in your hands, holding it with your fingers, just like when taking measurements.



    Steps

    With W / me2, I began to walk less. I noticed that the sensor is less sensitive to “false” steps, slight swings and movements of the hands during the work process, which significantly affected the number of steps taken. It seems to me that this metric is more accurate than other pedometers.



    All data is issued per day in general and in detail, for every 20 minutes.

    Calories

    The sensor records calories based on your activity.

    Distance

    Here, perhaps, everything is clear too.

    Sleep

    Tracking sleep is not in "smart mode", and this is very good. That is, to run the analytics of the time that you spend in a dream, you must switch W / me2 yourself. Considering both the reviews and my own experience about the errors of smart devices that try to independently distinguish the time when you fall asleep, this proposal seems to me correct.



    Data is saved to history.

    In history, you can find all your measurements of ECG, pulse and pressure, and in order to get to the date you are interested in, you need to double-click on this number with your finger.



    Alarm clock

    W / me2 does not have a smart alarm clock, but you can set the vibration signal at the right time.

    Inbox

    Also in the application settings you can set a notification about incoming calls.

    Guest mode

    It turned out to be convenient for me that with the help of one tracker I can quickly measure the pressure of all family members, and although the statistics of the guest mode are not saved, I like to have this opportunity. In this case, the data is submitted in the same expanded form as for a registered user.



    To improve the quality of readings in this mode, an “express calibration” is recommended, which is performed each time for a new guest measurement.

    Main menu and settings

    The “Main tab” shows your statistics for the current day, but for a quick comparison with the past days, you can swipe it up.



    On the left there is a full-fledged menu, from where you can get to the settings, where to specify the W / me2 operating mode convenient for you.



    Here you select the necessary notifications and reminders, set an alarm and manage some functions of the tracker. Here, as you said earlier, you “change hands” so that the display is equally convenient, regardless of whether your bracelet is on your right or left hand.

    On the right is the “express information” page: there are notifications, rise times, charge status and information about your profile.



    Profile Settings and Goal Setting

    The profile is filled in during registration in the device’s system, but during use you can change the parameters and refine them. W / me2 also gives you the ability to customize your desired goals.



    Conclusions and observations

    In my memory, this is the first bracelet with such characteristics, and here for me is an example of syncretism, since some functions were familiar to me, embodied in other forms. For example, ivansychev mentions Scanadu in a selection of mobile medical gadgets .



    The device is a compact sensor, very mobile, which facilitates the transportation of it from a business trip to a business trip. It measures heart rate, pressure and body temperature, as well as the level of oxygen in the blood. And everything would be fine, but not a bracelet, and I would still have to look for him some special place in the suitcase. To take it with you simply to the street, so that, stopping on the way to work, to measure the pressure - no longer with your hands. So, it remains to be recognized, a thing exclusively for the home. In this case, the pressure readings are quite plausible. Devices that W / me2, that Scanadu even cost ten rubles the same: 14,900 / 14,990 rubles.

    However, difficulties may arise during use. If you remember, Scandu must be applied to the forehead and also sit for about a minute, but it is important to guess with a point and sit almost motionless. Otherwise, the process can be endless, stretching all the time.



    Convenience

    Besides the fact that W / me2 fits perfectly into my value system, it is perfectly applicable in everyday life, and the family practically abandoned the usual electronic blood pressure monitor after we compared several times all the data on each of us. Moreover, we don’t have any special tradition to measure pressure, and we do this from time to time.

    Measuring pressure with W / me2 is a whole interactive process, with music, the rhythmic heartbeat, a floating jellyfish, an ECG pattern and a constant pulse display. And, despite the fact that the guest data is not stored, it was still very convenient for us.

    • Pacemaker


    My mother lives with a pacemaker, and we were not able to take any measurements using W / me2. The ECG line fluttered like crazy, with a huge spread of heart rate, and in the final we were never shown pressure!

    Comfort

    It is quite convenient for me to wear a bracelet as an accessory, periodically look at the watch and synchronize it without fanaticism, while maintaining the activity “home - work” in steps and distance. At first, I took measurements every day, now - less often, depending on the sensations of necessity. The tracker does not rub his hand, does not interfere with walking, and in combination with other bracelets or rings closes a peculiar composition. Here I even allowed to dream, and W / me2 as a whole in its place:



    Disadvantages

    In my opinion, the bracelet is easily soiled, and I have to wipe it with a napkin for glasses once every 2-3 days. Since he calmly tolerates the spray, I don’t take it off when I wash my face / brush my teeth; moreover, dust particles can collect during sleep. If you look closely, you can distinguish droplets, dots:



    Also, a couple of times I left him at home, forgetting, after taking a shower. But can’t I say if this is a lack of a bracelet?

    Need to do an action.

    We have long concluded that any additional action has become very burdensome. And no matter how convenient the bracelet is, it’s becoming more and more difficult to find a minute for it, so, of course, everyone would like it to measure in real time at some interval, and in the evening we just looked at the phone. But, unfortunately, this is still unattainable.

    Price

    Rooti

    W / me2 was made in Rootilabs, which before the change of name was known to you from the W / me bracelet, the stress tracker, which we wrote about on Habrahabr . Already under the Rooti brand came a miniature weather station Climate, an overview of which appeared on our blog thanks to marks . And the first review of the W / me2 tracker with a detailed description of what the autonomic nervous system is, how the gadget measures ECG and calculates pressure, wrote PetrosyanArsen .



    I stop here, as my experience with this is limited.
