The app does work, but to get the correct connection to your GPS watch requires some admin setup. Like everyone else, my watch did not work out of the box. I contacted Wonlex directly for help. I had to provide them with my country (USA) and service provider (AT&T), and they have made a code to text to the watch. After that, it started working. The app itself does function, but its not intuitive to use. To make the app better, someone with English as their first language should go through and re-word everything to sound more natural for English speakers.
