In this case it might not be as complicated as it seems, they might be using a Polar device for workout tracking, Suunto for marathon training/hiking, a Garmin as daily watch (payments, music etc). Add to that a Withings scale and an iPhone, and you're dealing with a melting pot of apps.

Yeah that's exactly that: - Polar watch + Verity Sense for workouts / running - Garmin pedals / monitor for cycling - Withings for the scale And I had to integrate .fit file upload for Zwift / Trainerroad trainings.
