disappointing experience

Very disappointing experience with KStyle OS. My Balancer watch does not stay connected unless I keep the app open. The moment I close the app, the watch disconnects immediately. This makes basic features like notifications and syncing almost unusable. An app for a smartwatch should run reliably in the background, not require constant manual intervention. Needs serious improvement.

Hand shake Wallpaper changed automatic. Very disappointed because I can’t put my favorite wallpaper

Very good app

With it, I have developed a healthy lifestyle. I go to bed on time, drink water on time, exercise on time, check my health data last year, and my weight data of daily exercise. I can watch the alarm clock and answer the phone.
