In effective and confusing – WearHeart Review

Both the user guide, and the prompts in the app are unclear. Should be reviewed by an English speaker. I have successfully charge the watch, and paired it with my phone, but the information that shows up in the app on my phone does not change. The charger is difficult to attach to the watch for charging. I plan to return the watch.
