🔧 Fix this

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

  1. A mobile app that calibrates wearable calorie data against actual weight loss trends over a 4-week period to provide a 'real' TDEE estimate.
  2. A browser-based calculator that allows users to input their specific age, height, weight, and activity level to generate a more conservative baseline for calorie expenditure than standard watch algorithms.
  3. A wearable integration service that flags when a user's reported activity levels and weight trends diverge significantly, prompting a manual adjustment of the user's metabolic baseline.
