### 1/5 — not connected

*2026-08-21*

this app isnt working at all

### 1/5 — smart watch

*2026-07-17*

dosent connect my apple phone

### 1/5 — disappointing experience

*2026-05-03*

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.

### 1/5 — Wallpaper changed automatic

*2025-08-12*

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

### 5/5 — Very good app

*2025-06-18*

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.

### 1/5 — Kieselect

*2025-06-05*

### 5/5 — Not opening app

*2025-06-03*

Last updates not working my phone.Not open this app from last update.

### 1/5 — HORRIBLE!

*2025-05-25*

This is literally the WORST app I have ever used and the watch is equally as bad. I can’t believe I wasted money on this. If I could give it negative stars I would.

### 1/5 — Not opening app

*2025-05-25*

Last updates not working my phone. Not open this app from last update

### 1/5 — App crash

*2025-05-23*

I used the app normally before updating it, but now the program crashes immediately when I open the app and I can't use it at all!
