iOS 18 brings GymKit to iPhone and AirPods, but what does it actually do?

Apple has expanded its GymKit platform, previously exclusive to the Apple Watch, to now include iPhone and AirPods. This update allows users to sync their fitness data directly with compatible gym equipment without needing a wearable device. By leveraging the sensors and connectivity within the iPhone and AirPods, Apple aims to make workout tracking more accessible and seamless for a broader range of users. GymKit facilitates a two-way communication between the user's device and the gym machine, enabling real-time data exchange such as heart rate, calories burned, and workout duration. While GymKit has historically struggled with widespread adoption in fitness centers, this expansion signifies a strategic shift to integrate Apple's ecosystem deeper into the health and fitness space. Users can now enjoy a more unified fitness experience, bridging the gap between their personal devices and professional-grade exercise equipment.
