Apple has published a new ad to appeal to customers in the market for an iPhone and Apple Watch pairing, highlighting the insights it can offer for your health.

Titled simply "Health with iPhone + Apple Watch," the half-minute ad focuses on a woman waiting in line at a cafe who begins receiving unsolicited health and fitness advice from other people in the queue, as well as local residents, drivers, and passersby – and even accompanying pets.

Amid the cacophony, she suddenly receives an Apple Watch notification about her new cardio fitness trend, and then looks into the Health app on iPhone to learn that her cardio fitness is above average. "Listen to your body. Not everybody," says the onscreen slogan, as she grabs her coffee and goes about her day. The YouTube blurb reads:

With iPhone and Apple Watch, you get science-based insights about your health. You see data on things like your heart rate, cycle tracking, cardio fitness, and sleep quality. So you can be more aware of what your body is telling you.

Apple Watch Cardio Fitness determines cardiorespiratory fitness as measured by VO2 max. VO2 max is the maximum amount of oxygen that the body is able to use during exercise, and it can be improved through physical activity. Apple introduced the feature in 2020.

Cardio Fitness is a category in the Health app on iPhone, and fitness level is classified as high, above average, below average, or low relative to people in your same age group and of the same sex. Users can also track how their cardio fitness levels have changed over the past week, month, six months, or year, and if fitness levels fall into the low range, they can get a notification on Apple Watch that includes guidance on improving it.
