In 2024, I reviewed another YHE blood pressure watch, but while its blood pressure monitoring was solid, the rest of its features and design left much to be desired. I couldn’t continue using it after my evaluation. However, after a month of using the YHE BP Doctor Fit 
The watch body is black aluminum, with two buttons on the right side and a slightly curved glass display. It looks and feels great. However, the clasp is positioned on the bottom part of the band, opposite every other watch I have, so securing it is a bit awkward.

Given that the inflatable cuff is positioned on the back of this part of the band, you cannot swap this half of the band. You can remove the top part of the silicone band with a quick-release pin.
A single press of the top button toggles the display on and off, while a press of the bottom right button toggles between the watch face and the app launcher. Swipe down from the top to view the quick controls, and swipe up from the bottom to view notifications.

Swipe right or left from the watch face to view different tiles that include daily readings, sleep results, heart rate readings, blood pressure results, and more.
Other applications installed on the watch include weather, a calculator, a workout with a wide range of sports, a calendar, a meditation app, and more. Still, I wish there was wider support for third-party applications, especially other health services you may use for logging data. The BP Doctor app is available for free for iOS and Android phones, and all of the data captured by the watch appears in the app.
