I've just asked a question about reliability of heart rate measured by fitness watches. I've noticed there are some question about fitness watches. I think it should be one, because it's quite a broad topic, and it's not limited to running.
Should there be a tag, and how should it be named? I hate the name 'smart' watches, because there's nothing smart in them. They just have some sensors, but this what they make with them is not always smart... GPS Watches is somehow broad in German (GPS Uhr) but it's not just GPS. Fitness watches maybe?
