Use of Apple Watch and HealthKit SDK for a project

Hello! We are new on Apple Watch development and we would like to ask some questions about Apple Watch and HealthKit SDK for a project. The goal is to get health data from the watch in order to process them. So:

  1. Can we activate multiple Apple Watches (10) using just one phone?

  2. If we create an Apple Watch App, can we transfer data from the watch directly to a server using an API or we must first transfer the data to the iPhone and then to the server? If yes, can this data be transferred using Wi-Fi or we need the cellular version of Apple Watch?

  3. Assuming that we will use the Apple Watches for research purposes, are there any limitations and/or regulations forced by Apple that we have to follow?

  4. Does HealthKit SDK has any limitations in place that will limit our capability to get all the raw health data?

  5. What health data can we get from the Apple Watch and at what resolution? Can we get the raw data or the data must first be processed by Apple’s Fitness/Health App and then transferred to the server?

Thank you!
