Ideas a builder, maker or community group could start on:

  1. A browser extension that pulls raw activity data and recalculates calories using standardized metabolic equations (METs) for comparison
  2. A community-driven database that benchmarks calorie burn accuracy for specific devices across different body types and exercise intensities
  3. A mobile app feature that allows users to calibrate their device's calorie algorithm by inputting VO2 max or resting metabolic rate data
