Diet Monitoring Is Where Tracking Becomes Useful

A diet log without weekly review is data with no decision. Most apps optimise for the data step and treat the interpretation step as a Premium upsell. Users end up with extensive logs and no idea whether the diet is working.

The fix is a free dashboard surfacing diet adherence, weight response, and key micronutrient gaps.
