Does smart tech really add that much to your fitness regiment?

I’m pretty plugged into the world of smartwatches and other fitness trackers, and a recurring theme is people crediting them for getting in shape. Apple Watch owners in particular will point to the Activity rings in the Fitness app, which encourage people to move every day. There are equivalents elsewhere, of course, such as the Heart Points in Google Fit, and the incredible amount of data available in Garmin Connect. That’s not even touching on the usefulness of apps like calorie counters and workout loggers.
