A pantry-first meal planning app that turns what's already in your kitchen into tonight's dinner. Built to cut household food waste and minimise grocery spending.
Product Intro
Plate Planner is a Web-first digital product that turns what’s already in your kitchen into tonight’s dinner. Users log their pantry by hand or by scanning barcodes, and the app suggests recipes based on what’s on hand, flags items about to expire, and auto-builds a shopping list for anything a recipe still needs. Streaks and badges like “Zero Waste Week” give a long-term sustainability goal an immediate, visible payoff. The biggest payoff of all, is seeing how much money and CO2 one has saved, sitting conveniently at the top of the dashboard page.
It’s built for busy, budget-conscious people who shop with good intentions but lose track of what’s in the fridge by midweek, then end up ordering in or throwing food out. They don’t want a rigid meal-planning system. They want to know what to cook with what they’ve already paid for.
Problem Statement
Roughly a third of all food produced worldwide goes to waste, and households are a major source. That’s rarely carelessness. Busy people simply don’t have time to plan meals, keep track of what’s in the pantry, or use up leftovers before they spoil. The result is wasted food, wasted money, and an environmental cost nobody intended.
People want to cook with what they already have, but lack the time, memory, or tools to know what that is before it's too late.
Users & Persona
Research identified four segments: Busy Families, who juggle shopping, cooking and leftovers for a household; Young Professionals, who are short on time and over-buy convenience food; Students, who need to stretch tight grocery budgets; and Eco-Conscious Consumers, who care more about sustainability than cost.
Persona: Mika, 24, The Budget Student. Alex shops with good intentions but forgets what’s in the fridge by midweek, then orders in or throws food out. Her problem isn’t motivation; it’s memory. She needs the app to tell him what’s about to go off and what to make with it, without having to log every item by hand.
How Might We
How might we help people know what's in their kitchen without pantry tracking feeling like a chore?
How might we turn "use it before it expires" from a guilt trip into an easy win?
How might we get someone from "hungry, no plan" to "cooking something" in the fewest possible steps?
How might we get someone from "hungry, no plan" to "cooking something" in the fewest possible steps?
These map directly onto the research: low-effort tracking, because 54% admitted to overbuying simply from forgetting what's at home; a positive framing for expiry, because guilt doesn't change behaviour but a good recipe suggestion might; and speed, because 72% said meal planning itself feels too time-consuming to bother with consistently.
Research Approach
Before moving into screen design, we validated the concept with a lightweight mixed-methods study: a 12-person survey and 8 in-depth interviews. The goal was to test the core assumption that forgetfulness, not indifference, is what really drives household food waste.
Findings & Insights
Three findings shaped the product more than any others:
People don’t stop caring about waste; they forget what’s in the fridge. 68% of respondents throw out food every week, and almost all blamed missed expiry dates rather than indifference.
Planning feels like homework, not cooking. 72% said meal planning takes too much time to keep up. The hard part wasn’t choosing what to eat; it was the upfront effort of figuring out what they already had.
“If something could suggest meals with what I already have, I’d save money.” This line from Priya, 31, became the app’s core mechanic, not a recipe database, but recipes matched to a real pantry.
From Prototype to Final
Early pantry entry used a full form for each item (category, purchase date, expiry, quantity, brand). It was accurate but hit our biggest constraint: high setup effort; nobody logs a whole pantry with that much friction. The final flow uses a single quick-add field with an expiry date estimated from typical shelf life. The full form is there only for corrections, and barcode scanning is an option for anyone who’d rather not type.
Recipe suggestions first appeared as a plain list, so users had to open a recipe to see whether it used what was expiring. The final cards show the match count up front (e.g. “9/10 ingredients matched”), making the reason for each suggestion clear before a single tap.
The biggest addition came from error handling. Testing showed that adding an item already in the pantry created a duplicate entry, quietly inflating the list and eroding trust in it. The final flow catches this as it happens with an inline prompt: “You already have 1x spinach. Update the quantity instead?”
The Final Product
Seven to eight screens cover the full loop.
Onboarding: three quick steps (goals, pantry setup, permissions), each under a minute, so setup never stops someone before their first useful recipe.
Home dashboard: pantry status, expiring items, and recipes you can make now, all on one screen.
Pantry list: add or edit items manually or by barcode, with colour-coded expiry pills instead of raw dates so urgency reads at a glance.
Recipe suggestions: filterable by time, cuisine and diet, with each card showing its pantry match count.
Recipe detail: ingredients split into “you have” and “you need,” with missing items added to the shopping list in one tap.
Shopping list: auto-generated and shareable, with each item tagged to the recipe that added it.
Expiry alerts: a carousel of soon-to-expire items, each paired with recipes that use it up.
Gamification dashboard: streaks, badges like “Zero Waste Week,” and an impact tracker that makes “less waste” a number worth checking.
Profile & settings: dietary preferences, household size and notifications.
