The problem

It started with my own fridge

I kept throwing away food because I forgot it was there or missed the expiry date. When I asked around, almost everyone struggled to remember what was in their fridge. It was a solo project done over one week, on a prompt of my choice.

Research

Why existing apps don't stick

I mainly followed design thinking. Before touching any design, I read up on the motivations behind goal setting, then looked at which food-tracking methods already work and where they fall short.

What gets in the way

01

Too much typing. Apps ask for a lot of manual input, which takes time.

02

Constant checking. You have to keep opening the app to track expiry dates.

03

No next step. No suggestions for food that is about to expire.

Interviews

Talking to people about their fridges

User interviews30+

data points from primary interviews. The questions I asked:

  1. How often do you throw away expired food from your fridge?
  2. How do you track expiry dates today?
  3. Would notifications about expiring food help you?
  4. Would you use an app that scans grocery receipts to update your fridge inventory?
  5. Would rewards for wasting less food motivate you?

What I heard

Organisation habits
  • Label items with purchase dates
  • Organise the fridge by expiry
  • A digital note on the phone
  • No tracking, just occasional checks
  • Rely on memory
Technology
  • Already use an app to track expiry
  • Scanning receipts sounds convenient
  • Love tech solutions
  • Would try scanning if it is free
  • Depends on how easy the app is
Food waste
  • Once a week
  • At least twice a week
  • Every other day
  • Often vegetables
  • Rarely, thanks to meal planning
  • Hardly ever, I eat out a lot
Notifications
  • Definitely helpful
  • A game-changer
  • Good for items hidden at the back
  • Need reminders
  • Maybe, if not too frequent
  • Not needed, I am organised
Motivation
  • Love rewards
  • Environmentally driven
  • Rewards are a win-win
  • Grocery discounts as rewards
  • Only if rewards are substantial
  • Not a deciding factor

Personas

Designed for students and young professionals

The research pointed to two groups who waste the most food for lack of time and planning. Click any image to see it full size.

Opportunities

From opportunities to product structure

I mapped the opportunities from research and turned the strongest ones into a simple product structure before designing screens.

The design

Five features, less typing

FEATURE 01

Scan receipts to add items

Scan a grocery receipt and the items go straight into your fridge inventory, instead of typing them one by one.

FEATURE 02

Notifications before food expires

FridgeBuddy tells you when something is about to expire, so you don't have to keep checking.

FEATURE 03

Track and deal with food

See everything in your fridge at a glance, with guidance on what to do with food that is about to expire.

FEATURE 04

Add or edit custom items

For homemade food or anything without a receipt, add or edit items by hand.

FEATURE 05

AI recipes from your inventory

Recipes suggested from what is already in your fridge, so expiring food becomes dinner instead of waste.

Prototype

The flow in motion

Scan a receipt, get the items in, see what expires first and turn it into a recipe.

Next steps

What I would add next

Product features
  • Group items by kind, placement and more
  • Coupons or points for wasting no food
  • A dashboard of what was eaten and what was wasted
  • Double confirmation to prevent mistakes
  • Partner with online stores, so there is no receipt to scan
Design
  • Higher colour contrast for text and icons
  • Voice: an Alexa or Siri skill to ask what is in the fridge
Honest noteWith only 7 days, I skipped usability testing. It would be the first thing I do next.
