You planned the week. You built a shopping list. Then you opened Instacart and spent twenty minutes fixing quantities, deleting duplicates, and guessing which "chicken" the recipe meant. App to Door is the opposite: your meal plan becomes a pre-filled grocery cart with store-ready items — one tap from MealPrept AI to checkout.

What "App to Door" means

Four steps, no manual searching:

1. Plan — AI generates a weekly meal plan tuned to your household, diet, and budget.
2. List — ingredients merge into one shopping list with store-friendly quantities.
3. Cart — tap Shop on Instacart to open a pre-filled cart.
4. Door — check out on Instacart for pickup or same-day delivery.

Why Instacart carts go wrong without a smart list

Manual meal planning and generic shopping lists cause the same problems every week:

• Recipe units vs store packages — three cups of milk across four meals should not mean three separate milk searches.
• Duplicate lines — olive oil for tacos and pasta should be one bottle, not two cart lines.
• Vague names — "chicken" and "oil" match dozens of products; retail-specific names match faster.
• No meal context — merged items are hard to sanity-check without knowing which dinners use them.

How smart meal planning fixes ingredient matching

1. Ingredients aggregate across meals

MealPrept AI collects ingredients from every recipe in your plan and combines them into a single buyable list. Shared staples — rice, eggs, olive oil — appear once with the total you need for the week.

2. Store package sizing

Recipe amounts convert into what you actually buy: gallons instead of cups, dozens instead of individual eggs, pounds of chicken instead of abstract "servings." That cuts waste and prevents under-buying mid-week.

3. Retail-friendly product names

Lists use names Instacart can match — for example boneless skinless chicken breast instead ofchicken. Units follow grocery standards (lb, each, package) so quantities land correctly in search.

4. One-tap Instacart handoff

From any saved shopping list, Shop on Instacart opens Instacart with items pre-filled. Optional address lookup lets you pick a nearby store before checkout. MealPrept is free — we may earn a small commission at no extra cost to you when you order.

Your App to Door workflow

1. Generate or build a weekly meal plan in MealPrept AI.
2. Create the shopping list from your plan (or edit items first).
3. Review quantities — adjust anything your household already has in the pantry.
4. Tap Shop on Instacart on the shopping list page.
5. Confirm substitutions on Instacart, then check out for delivery or pickup.

Before you check out on Instacart

• Scan merged items — quantities should reflect the whole week, not one recipe.
• Swap brands if your store is out; Instacart substitutions are normal.
• Pick your preferred store if you used address lookup — pricing varies by location.
• Keep your MealPrept list as the source of truth if you add impulse items in-store later.

Fits the rest of your meal planning habits

App to Door works alongside the guides you may already use: saving money on groceries, cutting food waste, and getting started with meal prep. The list is the bridge between planning and delivery — not a separate chore.
