Counter
A manual calorie and nutrient log. Pick a food, enter grams, and the day's totals update. All values are approximations from a public food composition reference, not lab measurements of what you actually ate.
What already exists
Calorie and nutrient tracking is a crowded space. This is a small manual log for the food ecosystem, not a competitor to the established apps below; see the full landscape survey for every subsystem, not just this one.

- Custom foods: let people add their own foods and values instead of only the 40 seeded here.
- Barcode lookup via an offline Open Food Facts database dump, so scanning a package fills in values instead of a manual food search.
- Weekly trends: a rolling chart of daily totals instead of one date at a time.
- Diet-profile targets: read the shared diet profile (style, exclusions) to flag entries or show a target range instead of raw totals alone.
