DT No.1 is one of the most popular second-tier China-based smartwatch makers. It is not going to compete with the top brands such as Apple or FixBit or even Xiaomi. Instead, it’s focusing on the mid-range and low-end markets. This also defines its strategy. The company launches a new model monthly. Moreover, there are cases when we see more than one models released in a single month. Of course, this also means those models won’t differ much from each other just because no manufacturer can bring too many innovations in so short period of time. But there is good news as well – when a company is offering so many models, you can find anything meeting your requirements, for sure. Today, we are going to review the latest addition to the company’s lineup, namely the No.1 DT28. Seems there is nothing special on this smartwatch, but the truth is we are dealing with a smartwatch, which is capable of measuring blood pressure.
In fact, we can’t say how many smartwatches with this feature are on the market. But one thing we can claim for sure – most likely, you won’t find anything cheaper than this. In this sense, the No.1 DT28 is considered to be the cheapest smartwatch that measures the blood pressure. But there are other features deserving our attention as well.
No.1 DT28 Appearance
The No.1 DT28 adopts a circular shape. The chassis is made of metal, we guess it’s covered with a zinc alloy. It has acceptable finishes. Due to this, the smartwatch is very lightweight of 59 grams only (with the straps).
The model we are reviewing is the black variant with a steel band. But there are also other versions of platinum and multi chassis and silicone band. The No.1 DT28 uses a standard 22mm detachable straps. So you can replace them with any you like. But we think you won’t because it already comes with quality straps. We have no complains on this occasion.
On the front, the chassis has a few indicative points that should help you know the time. Though the front panel has a circular shape, the screen comes with a square shape of 240 x 240 pixels resolution. It’s clearly seen when the display is on. Moreover, on the model we are reviewing, it was placed roughly. Maybe there is a trick. Say, this is done because the upper area is used more frequently. But we are not sure. Anyways, when using most of the apps, this is not seen. And even if the display occupies the entire front panel, you won’t use the edges.
There are two buttons on the right side of the chassis. The upper one is responsible for returning to the home screen, while the lower one take a step back. Honestly, it’s very convenient to use.
On the back side, we can see a few sensors and two connectors. If the former ones are for various measuring features, the latter is for charging. By the way, the No.1 DT28 smartwatch sports a 230mAh battery, which requires about two hours to charge. And this is sufficient for using 5-6 days.
Apart from this, the smartwatch is equipped with a Nordic NRF52832 chip, if you are interested in hardware. Plus, the No.1 DT28 has an IP68 waterproof rating.
No.1 DT28 Features and Functions
This is a regular smartwatch. So it’s logical to find many features we can find on other models. Say, the No.1 DT28 comes with a sedentary reminder, sleep monitoring, etc. But we are more interested in its core feature, which is the blood pressure measurement. We tested this feature on many people, and we have to say it works quite accurately. Of course, if there are real problems, we recommend to use professional equipment. But those who always want to keep the finger on the pulse (literally) and know everything about their health, can use the No.1 DT28 with no fear.
Apart from this, the No.1 DT28 also comes with ECG and hear rate monitoring. But we guess you are not impressed because these features are available on any smartwatch currently available on the market.
The next set of features belong to the hiking. There are apps for measuring the air pressure, altitude, the ultralight level, etc. These features requires an app connection.
The No.1 DT28 is ideal for any kind of sports as it has apps for walking, running, cycling, hiking, swimming, playing football, basketball, tennis, badminton, etc.
At last, as the No.1 DT28 can bind with smartphones running on Android and iPhones, there are a few useful features for this purpose as well. You can get notification for the most of social channels, see the caller ID, messages, and control music playing on your phone and so on.
No.1 DT28 App
To connect the smartwatch to your smartphone, you have to download the app called DT NO.I. As said above, there are some useful features working with your smartphone only.
The app interface is very simple and all functions are shown obviously. You won’t need much time to learn using this app. What we liked more is the ability of pushing notifications for many social apps like Facebook, Instagram, Twitter, etc.
The Bottom Line
The No.1 DT28 is promoted as a sports business smartwatch. We are not going to tell this true. Undoubtedly, this is not a business watch, and as for the sports watch, it has a more classic look. So what a category this watch belongs to?
This is the most interesting part of this review. The No.1 DT28 has many features for measuring health status including the blood pressure. There are many features for sports activity. It has an IP68 rating. The watch has a good build quality. And at last, it costs around $30. Combining all these, we can say the No.1 DT28 is an affordable smartwatch that is suitable for all kinds of users. The company didn’t put any luxurious feature on it and avoided of making this handset expensive. Instead, it brought many software features to regular customers.
