Overview

If you live with other people, you've experienced the chaos: someone buys milk when there's already milk in the fridge, nobody knows who ate the last eggs, and the grocery list is a text thread that nobody reads. Food management in a shared household is a coordination problem, and most tools treat it as a single-player game.

Tuna is built for households. One shared pantry, one shared grocery list, one shared meal plan — with everyone seeing the same real-time data on their own device.

Setting Up Your Household

Getting your household connected takes about a minute. One person creates the household in Tuna, then invites other members by email. Each person gets their own Tuna account with access to the shared household.

You can have up to six members in a household. Everyone downloads the app, accepts the invite, and immediately sees the shared pantry and grocery lists. No complicated setup, no syncing hassles.

If someone already has a Tuna account with their own pantry, their existing items can be merged into the household pantry when they join. Nothing gets lost.

Shared Pantry

The shared pantry is the single source of truth for what's in your kitchen. When anyone adds an item — by scanning a barcode, logging a grocery receipt, or manually entering it — it appears in the household pantry for everyone to see.

When someone uses an item, the quantity updates for everyone. If your partner uses half the block of cheese for dinner, you see the updated amount when you open the app. No more guessing whether there's enough butter for your morning toast.

This works for all pantry actions:

Adding items — scan a receipt after a grocery run, and the whole household sees the new items
Using items — cook a recipe or log a meal, and the ingredients deduct automatically
Expiration tracking — everyone sees what's expiring soon, so anyone can plan a meal around it

The shared pantry eliminates the most common household food frustration: not knowing what you have.

Shared Grocery Lists

The grocery list is shared in real time. When one person adds "chicken thighs" to the list, everyone sees it immediately. When someone picks it up at the store, they check it off and it disappears from everyone's list.

This means:

No duplicate purchases — if it's checked off, it's been bought
Anyone can contribute — noticed you're low on olive oil? Add it from your phone
Shop together or separately — two people at different stores can split the list and check items off as they go
Recipe integration — when you plan meals for the week, the missing ingredients auto-populate the shared list, minus what's already in the pantry

The days of texting "did you get eggs?" from the grocery store are over. The list is the list, and everyone's looking at the same one.

Individual Meal Logging

Here's where shared and personal meet. The pantry and grocery list are shared, but meal logging is individual. Each person in the household logs what they eat from the shared pantry.

This matters because not everyone eats the same thing. Maybe you had the leftover soup for lunch and your partner had a sandwich. You each log your own meal, and the pantry updates accordingly. Your individual nutrition dashboards reflect what you personally ate.

When you cook a recipe for the household, everyone who eats it logs their own portion. If you made a pot of chili that serves 6, you might eat 2 servings and your partner eats 1. Each person's calories and macros reflect their actual intake.

Privacy

Tuna respects that sharing a kitchen doesn't mean sharing everything. Here's how it breaks down:

Shared with household

Pantry inventory (what's in the kitchen)
Grocery lists (what needs to be bought)
Meal plans (what's planned for the week)
Recipes (the household recipe library)

Private to each person

Nutrition goals (your calorie or macro targets)
Meal logs (what you personally ate)
Nutrition dashboard (your individual numbers)
Spending insights tied to personal meals

Your partner can see that there are 4 servings of chili left in the pantry. They can't see that you ate 2 servings and are 200 calories over your daily target. Personal health data stays personal.

This balance matters. Shared logistics, private health. Everyone benefits from coordination without anyone feeling monitored.

Stop buying duplicates and guessing what's in the fridge. Set up your Tuna household in under a minute and get everyone on the same page — one pantry, one list, zero confusion. Download Tuna and invite your household today.
