Consider cancelling if…
You mainly want weekly meal ideas and a grocery list, and will manually check portions, ingredients and leftovers.
Keep the app when…
Keep Eat This Much if you rely on its nutrition-based planning, automatically updated grocery lists, delivery integrations or saved weekly plans.

Create a five-day dinner plan for [people] using my pantry ingredients first. Budget: [amount/currency]. Maximum cooking time: [minutes]. Equipment: [list]. Dietary preferences and allergies: [details]. Give me five varied meals with ingredient quantities, clear cooking steps and approximate preparation times. Reuse ingredients sensibly and plan how leftovers fit into the following meals. Do not describe an ingredient as allergen-free without label verification. Produce one shopping list grouped by store section, subtracting ingredients I already have. Separate estimated costs from checked prices; if current prices are unavailable, do not pretend the plan meets an exact budget. Offer cheaper ingredient substitutions and a short batch-preparation plan. Do not make medical nutrition claims. PANTRY: [list with amounts] PREFERENCES: [list]
