Apple took a big step into the health market on Monday with Health and HealthKit, a new app and platform for iOS 8 which will work to record all the fitness tracking information you rack up during the day. Health could potentially replace a number of popular third-party iOS apps, but in a series of interviews with 9to5Macs these developers say they’re looking forward to working with HealthKit in the future.

Several companies including Withings, RunKeeper, Strava and iHealth all say they’re looking forward to integrating into Apple’s Health app and developing for Health. “We are thrilled by the announcement of HealthKit’s availability,” says Withings CEO Cedric Hutchings, adding that a unified app for storing all your health data is exactly what its users want. That seems to be the general sentiment from all these companies, though several note that they still need to do a bit more research.

HealthKit has the potential to revolutionize mobile fitness tracking, and Apple is already striking partnerships with the medical industry starting with the Mayo Clinic. Whether third-party health apps can carve out their own slice of Apple’s Health app remains to be seen.
