I asked our friends over at TomTop if they had a spare fitness band they could send me to review since the previous one that I had cracked after dropping it near a pool, water finally made it’s way into my old smartwatch and destroyed it so I needed a new fitness band. I like fitness bands that are simple and used for tracking steps, heart rate and when they told me about the V07 and also noted that it supported blood pressure monitoring I was very interested as I had not reviewed a smart watch with blood pressure monitoring before.

Unboxing the V07 Smart Band
When opening the box for the V07 Smart Band what you get is the disassembled watch with both bands off of it, and the manual.
I prefer watches that slide out of the band and directly plug into a USB port myself, I never did like the watches that use clamps or clasps to pin and hold the watch in place to charge it as lining up the pins can be inconvenient.
The center part of the V07 has a blue tab and black tab, the blue tab is the USB plugin part which you use to charge the V07 Smart Band. All you need to do is make sure it charges for a few hours until fully charged before you start using it.
Plug it into a computer, a wall outlet or in my case a USB Hub and it will start charging, you can see the battery indicator light on the watch which let’s you know that it is charging.
The V07 Smart Band is a fitness watch that sports the NRF51822 chip and it has Bluetooth 4.0 technology for low power usage. This is one of the few fitness watches that features blood pressure monitoring manual or automatic which constantly tests the user’s blood pressure throughout the the day and reports it in the app. You also get heart rate monitoring both manual checking and constantly monitoring throughout the day as well.
V07 Smart Watch Daily Use and Battery
So in using the V07 for about 5-7 days between charges but this is also depending on how many alerts you have setup and how frequently it is buzzing or using up some of it’s battery vibrating and giving off alerts, it will have a longer lasting battery the less frequently it has to go off with vibrations.
The V07 fit band also sports the standard features like Pedometer / Sleep monitoring / Sedentary reminder (remind you to be active if sitting too long) The app and watch track and allow you to review your steps, heart rate, blood pressure and sleep habits. Though I was having some trouble getting the sleep data to sync to my iPhone 6 but it did sync some days and not others.
You also can get an estimate on calorie consumption with estimated calorie burn but it is only a loose estimate. The V07 smart watch also features call alert & Push Messages the watch face can display someones name or tel No. for call and also displays SMS content right on the watch itself. The watch supports notifications from Wechat, QQ, Facebook, Twitter, LinkedIn, WhatsApp, Instagram, Snapchat, Skype, Gmail and more. The V07 has a waterproof rating of IP67 which means it can resist splashes and rain but it is not waterproof and you cannot submerge the V07 in water. It is not a swimmers fitness band. The V07 is compatible with all Android Smartphones running Android 4.4 and later, as well as iPhones running iOS 8.0 and above.
To get the watch paired, download and install the Hband app from iTunes or Google Play
When you first setup the app it only allows you to set your height and weight in centimeters and kilograms, but you can change it to the imperial system after you setup the app the first time. The V07 pairs as the V07S with the phone and you can access a wide range of settings after pairing your watch with the app.
Brightness I find is an issue with all smart bands, and by default the brightness is set to auto, but you can adjust it manually to have the brightness as high as possible all the time though it decreases battery life. I still found in broad daylight the watch face was almost unreadable with sunlight out or direct bright light and you often have to cover the watch with your hand to shade it so you can see the time or data on the watch.
You can set the watch to go off just by turning your wrist and it can shine a light at night in the dark even if it is hard to read during the day, so you can set it so it won’t constantly light up if you move a lot in your sleep. You can have HR automatic monitoring constantly take your heartbeat as well but again when you have active automatic monitoring it does drain battery life more since it has to use more power to take the automatic measurements.
You have a Stopwatch function and a find my cell phone function in the watch, plus you can use the Hband app and watch to act as your camera snapshot button so you can use the watch to take photographs instead of tapping on your phone. When it comes to message notifications you can display phone calls, SMS, and various other messages on the V07 Smart Watch face itself, each notification you enable will show you messages from that app/service on your watch and the more you enable the more times your watch will go off for those services so pay attention to battery usage. It is nice though to be able to see who is texting or calling you just by turning your wrist instead of having to dig your phone out everytime.
The analytics you get from wearing the watch breaks down your daily activity and metering into days, hours and minutes.
You can even see your activity times and get a good pattern for when you are active and when your sleep activities are.You notice just below it says no sleep data, but that was because it didn’t pick up sleep data on 12/27 for some reason but it did on 12/28 which you will see below. You can see how it is constantly taking measurements on heart rate and blood pressure as well.
Here is the snapshot of my sleep data from 12/28 showing I had 7 hours and 15 minutes of sleep, and my 5 hours of deep sleep and just over 2 hours of light sleep.
Looking at my heart rate monitor for 12/30 you can see how it breaks it down every half hour and then shows you a bar graph showing you mow much is in the rest state, to strenuous state.
Blood pressure is very interesting for a fitness watch and it automatically takes it every hour, it is accurate within +-5 when comparing it to a wrist pressure cuff, but I am not quite sure if it is using the same green laser light to read the blood pressure as the heart beat. See my blood pressure normally falls within these ranges when I am using my wrist monitor and the times of day seem to be pretty on point. I would not however trust the blood pressure monitor as a medical device myself, there just isn’t enough information and I don’t think the same sensor as heart rate can give a very accurate blood pressure read. I think it could give general reads giving you an overall indicator when looking at analytics over time, but I wouldn’t rely on the blood pressure data.
Heartbeat readings however were fairly accurate and similar to a red finger light heartbeat monitor as well as the iPhone heartbeat reader apps which have you hold the phone camera to your finger so it can shine a light and detect your pulse. The blood pressure was interesting and surprisingly within range, though it showed my highest BP was 148/99 which may have been an anomaly. It also states you have to be completely still for any degree of accuracy on the blood pressure monitoring part.
Overall at $36.16 USD this V07 Smart Watch which you can pick up on TomTop was very impressive with it’s feature set and usability for the price. I like the Hband app better than VeryFit 2 and this is my new go to fitband that costs under $40.
