### 1/5 — 语言无法设置

*2026-07-13*

手表上都是英文，简体中文无法设置，也不知道在哪里设置，都找遍了就是没有，

### 3/5 — 总是断开连接

*2026-07-09*

有时候总是无法连接，连接上也不同步手机，用着用着自动断开

### 4/5 — Bien

*2026-06-13, version 1.61.14*

Cumple con lo básico, fácil de emparejar con el reloj. 
*Recomendación: NO actualicen el firmware del reloj porque borra algunas opciones como el oximetro y no hay vuelta atrás.

### 3/5 — Connect to watch issue

*2026-05-31*

Totally blank to my watch

### 5/5 — Cool watch

*2026-04-08*

I got a watch for Christmas and this watch was amazing to me and this app really helped me understand how to work my watch and how to keep track of my health

### 4/5 — Ok 👌

*2026-04-01, version 1.61.10*

I think that the app could use some work. I don’t always receive my calls but other than that the app is pretty good not great but good . It’s hard to sign in so I had to you the guest profile but connection is good .🙂

### 5/5 — A very good watch

*2026-03-28, version 1.61.10*

It is the probably the best watch I ever got!!!!!!!!!!!

### 5/5 — Запрос на предоставление информации

*2026-03-22*

Уважаемый разработчик, подскажите почему перестали синхронизироваться новые дисплеи часов? И пропали из собственной истории ранее сохраненные циферблаты. Почему это происходит. Вы больше не будете поддерживать приложение?

### 1/5 — Ошибка

*2026-03-18*

Почему часы отображают информацию на день раньше!
То есть, вчера 17.01, часы показывали информацию как за 16.01, хотя часы были активированы только
17.01.
За 18.01 часы отображают информацию, как будто это было 17.01
Из за этого, скорее всего, не происходит синхронизация по шагам с телефоном, прошу сообщить, как это исправить.

### 3/5 — 𝓢𝓪𝓽𝓬𝓱
