Apple Expands GymKit to iPhone and AirPods Pro 3

Apple expands GymKit support to the iPhone and AirPods Pro 3 with iOS 27, extending the gym equipment connectivity feature beyond Apple Watch for the first time.

GymKit originally launched in 2017 and has, until now, been exclusive to the Apple Watch feature, requiring users to wear the watch and tap it against compatible equipment to pair. The expansion means that iPhone and ‌AirPods Pro 3‌ users can now also connect to supported cardio machines, including treadmills, ellipticals, bikes, and stair-steppers, for more accurate real-time workout metrics, without needing an Apple Watch on their wrist.

The feature works via two-way data exchange, syncing metrics such as speed, pace, distance, calories, and heart rate between the device and the machine in real time, with the goal of aligning what the user sees on their device with what the equipment displays.
