Recently, I have received the Doctor V DV-1 Personal Fitness Tracker device from a Taiwanese tech firm called ViseeO of which I used to purchase their wonderful Bluetooth handsfree car kit for my Mercedes.
Doctor V DV-1
My first fitness tracker is a Mi band and Doctor V unlike any other health related trackers on the market is unique in the way it measures the heart rate, and and also it has UV sensor and an alcohol breathalyzer which you can use to test your Breath Alcohol Content level (BrAC) or Blood Alcohol Concentration (BAC) through conversion from BrAC.
The first impression of Doctor V DV-1 is the fee of Apple's white packaging quality and a window display of the product. When you open the box, you will find the main product, an instruction guide and a protective flannel bag for the DV-1 unit if you wan to want to carry it with you all the time.
Setup Doctor V DV-1
The setup is easy and very straightforward. Plug Doctor V into the bottom of your iPhone (packaging says it is compatible with i7, i7 plus, SE, i6s, i6s plus, i6, i6 plus and i5s). iOS will ask if you would like to install the App for Doctor V and re-direct you to the app store.
After installing the app, Doctor V app as it is called will launch automatically every time you plug in the device to your iPhone.
UI and UX
Doctor V's app user interface is a simple 4 icons UI which is very easy to operate and understand. Each function has its own user interface and user can switch between the different function without going back to the home menu.
You can customize the background color in the home setting or change the sound of the heart beats in the heart rate setting which is a small bonus. However, while the home menu is in the portrait mode all four other functions' screen are in the landscape mode only. I guess it's because the company wants you to operate the device in a landscape mode.
Features
Doctor V contains 3 major & 1 minor functions: 1. Heart rate measurement, 2. Alcohol Breathalyzer, 3. UV level detector, and 4. History.
Heart rate measurement which according to the specification is similar to a Fibit band which use a PPG based solution however a big difference is Doctor V use finger instead of wrist to measure the blood flow rate controlled by the heart pump using light and sensors. PPG can give you heart rate/pulse rate and blood oxygen information. What is unique about Doctor V's PPG solution is that it also allows user to see their own pulse curve in real-time, which is rarely seen on any of the fitness device on the market. What's more, the entire session of the heart rate measurement including the pulse curve can be recorded by simply press the recording button on the app screen, and user can play it back from the History function of the App. If you do not record the session Doctor V will simply display the max, low, and average hear rate or blood oxygen level observed.
Alcohol Breathalyzer in Doctor V is another unique and unseen feature in any fitness tracking device throughout the market. Doctor V has an alcohol sensitive gas sensor that can be used to test the alcohol concentration level detected in the air. This allows Doctor V to measure the breath alcohol content (BrAC) or blood alcohol content from blowing the air from your mouth. I have tested the Doctor V against a pro-commercial grade breathalyzer from ACS and I would say 8 out of 10 times it is showing a similar reading as ACS unit (with 5% difference). However, the App warns you that if you are in a smoking room or if you have just smoked at the time of testing Doctor V will pick up the smoke concentration too which affect the accuracy of the alcohol concentration result. As I am not smoker so I am not sure what's the real effect of smoking on the accuracy of the sensor.
UV measurement is useful function that Doctor V provides. The UI has a distinctive circle which measure the maximum UV observed during a testing session while the bar on the right give you a real-time change in the UV level observed. You can test the environment UV level and Doctor V will give you suggestions such as the time that you will get tanned under the detected UV level. It also has more complicated setting such as skin type, terrain, and SPF selections to give more accurate information of the sunburn calculation. It also suggests protection wear or measurement such as hat, sunglasses, and required SPF sunscreen for different level of UV.
History function is where you can view all your measured data. One particular feature which has been mentioned earlier is the playback button in the heart rate data if you have recorded a particular session of heart rate measurement you can playback the entire recording from here including the pulse curve. Otherwise the heart rate will be recorded in a simple data format such as max, low, and average heart rate and blood oxygen level observed.
Conclusion
Doctor V DV-1 personal fitness tracking device is a compact, cool and very easy to use device that can be easily carried in your pocket. The functions are unique and useful for our everyday use and can be used to assist us for having a healthy and good life style.
