According to the latest Power On newsletter from Mark Gurman, Apple is working towards turning its upcoming non-AR smart glasses into another platform for health and fitness – though these features likely won’t debut with the first generation model in the coming year.

Per his reporting, Apple had already been working towards using Vision Pro as a health platform. The company was apparently working on a version of the Fitness+ app that would run on the headset, allowing users to watch workout videos, track their movement, and close their rings inside of Apple’s first generation spatial computer.

There was going to be some special body tracking analysis to set it apart from something like an iPad or Apple TV. However, due to the weight of the headset, the company abandoned its plans:

One initiative was a version of Apple Fitness+ that could run inside the headset. The idea was to let users wear the device while working out and following classes, with the headset using its body-tracking technology to analyze movements. But this never launched due to technological hurdles and the headset itself being too heavy.

Nonetheless, the company is revisiting a similar idea with its upcoming smart glasses – though it’ll have to be a bit different due to the lack of displays.
