Healbe GoBe is a project from St. Petersburg. The company has already released 2 smart bracelets that are known for the ability to automatically calculate not only the calories consumed, like most fitness trackers on the market but also the calories after eating. How successful Healbe GoBe 2 copes with the declared functions, and we tried to understand the review of the bracelet.
Healbe GoBe 2 comes in a transparent plastic case, which contains the bracelet itself, a stylized purple Micro-USB cable, a docking station, and instructions. Initially, the device seems very cumbersome, so some time to such a size and weight will have to get used to. Nevertheless, the design is quite strict and versatile, with a bit futuristic. Healbe GoBe 2 comes in black only, but you can buy replacement straps of other colors. The screen has a ribbed texture, information on which is displayed using a group of blue LEDs. In the bright sun, the display will have to peer to see the time or to recognize the data about its activity, in other scenarios the information is easily readable.
Also on the central unit, there is one mechanical button to move between the indicators to display the time. The strap of silicone and, according to manufacturers, hypoallergenic. About the last point, we had doubts, because, with long everyday wear under the bracelet, redness and itching appeared, although using the same Mi Band, such problems did not arise. The manufacturer himself recommends daily wiping the bracelet with a damp wipe without alcohol.
Operation of sensors
Clever Bracelet Healbe GoBe 2 is equipped with an accelerometer, piezo sensor, gyro with a magnetometer, sensors of skin galvanic reactions and bioimpedance. All this, in theory, allows you to monitor consumed and spent calories, monitor the emotional state, monitor the water balance and pulse.
As for the main feature of an intelligent bracelet – calorie counting, then everything is not so unambiguous. As the manufacturer claims, for this is the specially developed Flow technology. After eating, the body begins to convert carbohydrates from food into glucose. Insulin encourages cells to absorb glucose and give off the water. And GoBe 2 fixes these processes and the dynamics of extracellular fluid and using a bioimpedance sensor can determine the number of calories consumed and the level of proteins, fats, and carbohydrates. In practice, information about the energy balance is by no means always believable and correct. Even with a minimum daily load, the balance was negative, that is, in favor of the calories burned, which, by the way, the bracelet thinks is good.
In addition, Healbe GoBe 2 constantly monitors the water-salt balance of the body. When the level of hydration is almost at a critically low level, the gadget notifies the owner that it is necessary to drink water. You can see how things are with the water balance both in the application and on the device itself. This function works quite accurately.
The smart bracelet can follow and stress level during the day. At moments of emotional stress, Healbe GoBe 2 begins to vibrate, and the word “Emotion” appears on the screen, which means that you need to relax and take a deep breath. Track the emotional activity can be and on the chart in the application.
There is a function of tracking the phases of sleep. After waking up in the application, information on the quality of sleep will be available, namely how much time you spent in deep sleep, how easily you woke up, and so on. A detailed schedule will also be available in the application. Also, collecting information about your activity during the day, the bracelet calculates the recommended amount of time for rest. There is also a smart alarm clock – Healbe GoBe 2 vibrates at the moment when you are most ready for it, that is, during a short or easy phase of sleep. The application configures the time interval for waking up.
A piezo sensor helps to monitor the pulse. It measures the heartbeat frequency every 5 minutes, after which the data appear on the graph. Thus, you can have a general idea of the work of the heart during the day. Also recently, in the company application, it became possible to measure the pressure, although, while this function is available only in the test mode and the level of error can be 20 percent, the application warns about it.
I can not help saying that all of the above functions will not work if the sensor does not fit snugly against the wrist. Therefore, the bracelet must be worn very tightly, and this causes discomfort. If the sensor does not recognize the wrist, then after triple vibro-warning is turned off. In the prone position, the hand is recognized by the sensor worse, so with the tracking of sleep in our case a couple of times there were problems. The next update should solve this problem.
The bracelet has a proprietary application Healbe GoBe. It is very simple, intuitive and contains a minimum of settings. The interface is divided into 5 parts: energy balance, current hydration level, pulse, sleep and stress level. In each, you can get detailed information. The downside of the application is that synchronization does not occur in the background, and every time you enter it, you need to wait for it to process the data.
The Healbe GoBe 2 has a 350 mAh battery. On average, the bracelet is enough for one and a half or two days of use, which is very small for a fitness bracelet. It charges about two hours.
The idea with the automatic calculation of derived calories and tracking the energy balance seemed really interesting, however, was the realization of the idea of “raw,” especially given its price ~256$. Healbe GoBe 2 – a device with broad functionality, while there are obvious trade-offs in the form of an inaccurate display of calories consumed, not the best of autonomy and massiveness. It is also important to say that there are no notifications from the smartphone. Otherwise, the device is turned stout, and Healbe GoBe project definitely has a future.
