2. Wearables Integration as Competitive Differentiation

TeamBuildr's Phase 1 and Phase 2 wearables integration leverages iOS and Android health kits rather than direct device manufacturer integrations, a deliberate architectural choice reflecting market realities.

Core Metrics (Phase 1): Exertion Score (0-10) calculated from:

Average heart rate
Heart rate variability (HRV)
Passive calories (BMR) and active calories burned
Step count
Sleep hours

Supported Devices:

Apple Watch (fully compatible, automatic sync)
Garmin
Whoop
Polar
Oura Ring
Other devices syncing through Apple Health/Google Fit

Evidence of Market Fit: The documentation states this approach accommodates "95% of sports programs that lack resources for single-vendor equipment purchases, enabling broader participation through devices athletes already own."
