Function:
1. Synchronize and display the movement data on the watch.

### 2/5 — Worked great til it didn’t

*2025-11-02, version 1.7.7*

I didn’t mind the occasional connection drops, considering the price of the device. However, now it will not connect to the app so I am update the time. Went through all the recommended steps and nothing. Maybe they stoped supporting this watch. Disappointed.

### 3/5 — Error

*2023-07-09, version 1.7.7*

It used to work fine but now it will send a message that reads “error cocoa 500”. It won’t register my workouts ir steps. It does sync to the watch but nothing registers.

### 2/5 — Cannot manually add steps

*2023-06-29, version 1.7.7*

I got this watch to track my fitness journey. I walked three miles today and it picked up no steps. You cannot manually add steps unless I’m missing it somewhere. It seems to not pick up basic activity
