Apple (AAPL.O) is developing a screenless health and fitness tracker similar to
Whoop, sources say. The device is part of a retooling of Apple’s smartwatch
product line and an exploration of new wearable technologies. Sources say the
company has spent months researching the area and is building prototypes. The
project has senior management backing but Apple has not decided whether to
launch it. The initiative is in an early phase internally dubbed "technology
investigation." If Apple decides to release the product, it is unlikely to ship
before 2028.
