Device compatibility & analytics capabilities — questions before full integration

Hi all,
I’m building OrgHub, a SaaS platform for endurance sports clubs in Greece (running, cycling, triathlon).I’d like to confirm a couple of things before we go deeper with the integration:

  1. Device sync coverage
    When a coach pushes a structured workout to an athlete’s Intervals.icu account, does it sync automatically to all major devices? Specifically:
    Garmin ✓ (I assume yes)
    COROS
    Suunto
    Wahoo (ELEMNT / Bolt / Roam)
    Polar
    Apple Watch (via any workaround?)
    Any known limitations per brand?
  2. Analytics & charts
    For a coach dashboard showing athlete progress, what’s available via the API? I’m mainly interested in:
    Fitness / Fatigue / Form (CTL / ATL / TSB)
    VO2max estimates
    Power curve & pace curve
    Training load distribution
    Can I pull these as data (for my own charts), or is there a way to embed the Intervals.icu charts directly?
    Thanks!
