I have not exactly had any problems with the Swatch Touch Zero One watch itself. I was confused, I’ll admit, by the swiping movement to navigate the menus, having read the manual, so I looked up a video on YouTube and was fine after that. However, when it comes to the app for iOS, it simply doesn’t work. I can see my iPhone 7 Plus connecting in the Bluetooth part of “Settings”, so at least the watch is unlikely to be at fault, but the Swatch app doesn’t see the watch. I did see it briefly once, but each time since then it hasn’t appeared. On that one occasion, the watch went out of Bluetooth mode very quickly when I clicked on it in the app. Also, each time I restart the app, I have to scroll down the terms of use to agree. So that’s it: I simply cannot use the app on a new iPhone. A total failure of an app, and it made me think of the Star Wars line “What a piece of junk!” in the exact tone: fitting for a youth product, I’d say (I’m 36.)
