Why NOM exists
Most meal-planning apps are calendars with recipe photos. Most nutrition apps are spreadsheets with guilt. NOM is the missing middle: plan the food your household will actually eat, and let the software carry the nutritional and logistical bookkeeping.
That means the boring-but-hard parts are the product: merging three recipes' ingredient lists into one shopping trip, knowing a “cup of flour” is about 120 grams but stores sell it in 5-pound bags, remembering that your daughter's nut allergy applies to every search, and not suggesting salmon twice in a week when the plan says fish once.
NOM is built and run as an independent product. It's Apache-2.0 open source because food logistics software is infrastructure for a household, and infrastructure you depend on should be something you can inspect and take with you.
The name
Officially: Nutrition Optimization Machine. Actually: the sound dinner makes when the planning part is already done.
