Design And Build Quality

Design is unparalleled on the KUMI KU6, the new Apple Watch-inspired design is fantastic it brings a modern and elegant design that makes you want to wear it as an accessory not to mention its functionalities, I can see it as one of the best budget original smartwatches, and you notice a slight difference from the Colmi C60. So the shape is as usual a square with a 1.91-inch screen and 2.5D curved glass in a metal frame with a brushed finish, giving it the look of an expensive watch, and it really is amazing. On the sides, has one rotatable button for on-off, and back. To make calls, just below the button, you’ll find the microphone, plus holes in the left part, which is the built-in speaker.

There’s nothing out of the ordinary on the lower side, just made from Zinc Alloy with a sensor responsible for all the health and sports features on the device, and with magnetic charging pins.

Despite being a budget smartwatch, KU6 feels sturdy yet comfortable, looks elegant, and gives a premium vibe. So, the build quality is high and can be seen through the body, which is slim and light and made of high-quality Stainless Steel with a matte finish. The dimensions are perfect with a 47mm large size and 11.3mm thickness of the frame, and lightweight does not exceed 40g, which makes it comfortable on the wrist.

The strap is one of the important things to complete the overall look of the watch, that’s why it is made of silicone, it’s lightweight and comfortable on your wrist for long-lasting use. And because it’s removable you can use any 22mm belt and is available in colors Black, Silver, And an additional choice you can buy another from metal or leather.

Display Screen

Now, let’s move on to why I fell in love with this smartwatch. The most prominent development of the latest smartwatches is the display, This is what makes the screen in KUMI KU6 my favorite type a 1.91-inch IPS display its larger and slimmer bezels, enabling you to see more content on the tiny display than ever before, it’s a lovely punchy display with vibrant colors and because it is larger than other smartwatches being one of the few original smartwatches that are the same size, the images displayed on the screen are clear thanks to the high resolution of 320*385 pixels and a high pixel density. And with an extremely narrow bezel, the display area is increased by about 20%.

If you think we’re done, you’re wrong because the screen is perfect and that’s what makes it a pivotal selling point. it will provide you the best experience you can possibly get on budget devices, special thanks to the color accuracy and sharpness, the image is clear and rich, and even under direct sunlight, you’ll be able to use your smartwatch with ease whether you want to read notification or check your health stats, you won’t need to get your phone out of your pocket.

And as I always say, the reason makes this type of screen is my favorite is that large and takes over most of the interface, with narrow sides, and this is only found in smartwatches with higher costs. I personally prefer this screen over others and would love to see it used more.

Multi Watch Faces

If you are tired of the system default dial background, KUMI has made a concerted effort to tailor the plethora of watch faces included on the KUMI KU6 that’s why brings you many different pre-installed watch faces to choose from, you can switch between them easily in many ways, by long pressing on the home screen or via the KUMIWear app for more watch faces with over 100 online watch faces are available for download. and it’s included a variety of colors, retro, analog, 3D, and digital faces, or you can even use your own photos as a watch face background or any wallpaper and have the possibility of customization. And with the wrist-raised feature to wake up the screen, that would be great.


KUMI KU6 Smartwatch has IP68 Waterproof, which it means can only handle sweat and splashes of water, although the watch is not approved for swimming but is good for wearing for activities, so, I do not recommend swimming or exposing it to hot water or saltwater to avoid any harm Long or short term and with the presence of a speaker and a microphone, avoiding it will be good, however, if it’s exposed to water in any way, I prefer to dry the watch after immersing it in water and before operating it so that it stays with you for as long as possible.

Although it has a VcareVP60 sensor that is more accurate than other sensors, this does not mean that the measurements provided by this smartwatch are completely accurate, as most of them are largely unreliable because it’s not a medical instrument, but it makes you very aware of your health and physical performance. unfortunately, this is often the case with watches in this price range.

How To Pair The KUMI KU6

For you to enjoy the many benefits of your KUMI KU6 Smartwatch, you would have to connect it to a support app. The recommended app is the KUMIWear app which has loads of beneficial features to keep you fit and healthy, and it’s compatible with Android and iOS, so you would need to download it on your mobile phone. It is available on Google Play and App Store for both Android and iOS users.

For pairing, it’s easy to connect the Btalk to your phone. After installing the KUMIWear app and setup, all you have to do:

  • Step 2: Next, you would need to Sign up for a KUMIWear account. Or, Log in to your existing account (if you already have an account).
  • Step 3: Allow all notification data. A notification interface will pop up requesting your permission to allow the app access to certain functions on your mobile phone. (Denying any of these permission requests might prevent KUMIWear from working properly).

When all this is done, it will communicate directly and without any complications, with automatic setting of time and language, weather, in addition to a phone call feature, and update the smartwatch software if available.


The KUMI KU6 smartwatch works in concert with the KUMIWear app which expands the things you can do with the smartwatch by adding a lot of features, first, the app has the health menu where it displays all the data collected by the smartwatch such as the steps walked today, your daily goal, the number of calories burnt and the distance traveled, you can click on the label to expand it to show you more information on broader time frames such as the weekly and the monthly, right underneath we find the sleep monitoring label, we click on it to expand and it will show us light and deep sleep information, total sleep and awake time and the collected data from a week or a month, all displayed in a nice graph. It also has the heart rate, and blood pressure, each one has its very own label to click and expand then you can either start measuring or check the previously collected data.

Main Features of the App

The app I found perfect through the features and settings equipped which include watch faces, wallet, business card, notifications, health reminders, NFC, and more settings like adding favorite contact lists.

Bluetooth Calling Function On KUMI KU6

The most important feature of the KUMI KU6 Smartwatch is that it’s equipped with an integrated 2 microphone for better noise reduction and a speaker, with the former serving up surprisingly clear sound that can be heard over general din (such as road noise), making it usable, As for the microphone, it’s mainly used for on-wrist calls or, if you’re paired to a smartphone. So it not only displays an incoming call but can also receive and dial calls made via Bluetooth directly from the watch with good sound from the speakers and a mic, and of course, this is done with your smartphone, So you don’t have to take out the phone of your pocket every time you want to make or answer a simple call.

Notifications & Messages

Notifications are clearly visible and easily readable. And you will not miss out on important messages or notifications with KUMI KU6 on your wrist. It syncs up with your smartphone to display incoming calls, messages, social media notifications (Facebook, WhatsApp, Twitter), and other applications, enabling you to stay connected even when you’re on the move.

Battery Life & Charging Time

The battery in smartwatches is no less important than the rest of the functions, the KUMI KU6 offers great autonomy that is considered one of the best amongst the competing smartwatches, it packs a battery with a capacity of 300mAh, and through my personal experience it lasted with me for around 7 days with continuous usage of the sensor for heartbeat monitoring, in standby mode, it is supposed to last around 15 days which just makes convenient to charge it and take it whenever you want to without worrying much about it dying suddenly.

Final verdict
