Sustainability

Problem

Sustainability and nutrition are seen as expensive, time consuming, and overwhelming.

91% of users report feeling guilt around their food habits.

Making better choices feels like a luxury when budgets and schedules are already at their limit, and navigating conversations around food habits often demands too much from people who are already stretched thin.

Goal Statement

Give people a way to do just a little better within their real circumstances, and make that feel worth celebrating.

Outcome

A mobile app that helps users make small, budget-conscious swaps in their grocery choices, showing the compounded impact of those swaps over time without pressure, guilt, or the need to be perfect.

72% of users stated interest following initial demo, with 85% stating special interest in personalized product suggestions.

Discover

Gotta eat to live, gotta live to eat

Research shows that above all else, people are doing what they know to be the best they can.

They're tired, and the framing of these conversations treat socioeconomic realities and cultural perception as a choice or personal shortcoming.

Literature review

A comprehensive literature review on nutrition and food sustainability revealed three consistent themes.

These would serve as the foundation of all design decisions moving forward.

Research Findings

Cost

Consumer culture has made expensive synonymous with better, causing the assumption that you have to spend more to eat better.

Labor

When you already assume the better option costs more, researching it feels like an additional problem and adds mental and emotional labor.

Perception

The rhetoric surrounding sustainability is commonly built around sacrifice and failure, prematurely shutting people down.

Expert interviews surfaced this consistently. Guilt tripping has a boomerang effect, producing no change or actively negative outcomes.

"Sustainability is a need proven by science. The public dispute is all about communication."

"Consider the lens of 'Ok, you failed, now what?' Maybe the target audience is people who feel ashamed and don't know how to come back."

Core pain points

The research revealed my core goals for the product.

Most sustainability messaging assumes ideal circumstances. without providing alternative options .

Convenience is often the only realistic option, but nothing helps users make the best of it.

Pass/fail goal frameworks make progress feel binary and failure feel inevitable.

Defining the user

The user persona placed what I'd discovered into context and define the core goals moving into ideation.

"I know I should eat better and be more conscious about it. But by the time I'm done with everything, I just grab whatever's there."

I don't have the time or energy to figure out what the 'right' choice even is."

Goals

Convenient meals that don't require major sacrifice

Sustainable habit that make sense for him

Save money without giving up time

Choose the best options when access is limited

Celebrate small wins

Pain Points

Strict budget makes sustainable options feel inaccessible.

Guilt when convenience wins.

Juggling multiple apps that each only solve a singular need

Generic tips that don't account for his budget or schedule

No way to compare options quickly when he's out

People already want to do better, I need to make it easy

How might we help users make small, meaningful improvements without adding to their cognitive load?

Why current apps don't solve it

Nutrition apps alone can only solve part of the problem. Many of these tools only address one part of the problem, or just add more tracking, more judgment, and more opportunity to fail.

market sentiments

40% of users who had previously used a nutrition app stopped due to loss of interest or relevance.

Design principles

Based on the research, I set 3 principles for every layer of the design.

Flexibility

Features need to adapt to real life circumstances without requiring perfection.

Simplicity

Only information that directly pertains to the user should be shown, anything else is visual clutter.

Balance

Everything should prioritize the balance of cost and convenience without inherently requiring sacrifice.

Key features

A prioritization grid determined my MVP features.

Scan and compare

Barcode scanner for quick, in the moment decisions.

Smart lists

List building that can be optimized for cost, sustainability, or a customizable balance.

Suggest and swap

Product swaps compare similar products that vary in price and sustainability.

Design

Not perfect, just greener

A system of features designed around real life, not ideal conditions

Greener addresses the most common barriers within users' lives. Real-time comparisons, one-tap swaps, and a tone that treats any improvement as progress.

Low stakes, high impact

Onboarding

A short onboarding quiz collecting dietary preferences, monthly budget, and sustainability goals to power the personalization engine right off the bat.

App onboarding screens with questions about user preferences.

Options to continue as guest keep the experience low pressure and ensure that convenient features such as "scan and compare" are accessible right off the bat.

Progress isn't linear

See your progress compound

A simple chart on the home screen frames every choice as movement toward being Greener.

Any swap improves your baseline. There's no floor to fail through.

Pass/fail goal frameworks make progress feel binary and failure feel inevitable, so users need evidence that small choices have momentum that's adding up over time.

76.6% said they value insight visualization in apps they frequent.

flexibility and balance

Lists built for flexibility

Smart lists suggest swaps and alternatives, ranking similar product along a dynamic scale that balances users' budget and sustainability.

No option is wrong, you just pick what works best for you,

Users didn't have a quick way to evaluate their options against cost and sustainability at the same time.

In early feedback sessions, 85.1% stated personalized grocery suggestions had the most positive impact on their sustainability habits.

Conevenience is crucial

Compromise doesn't mean giving up.

Scan and compare measures any two products side by side across sustainability, nutrition, and cost in order to help users still know their best options in limited selections.

Convenience stops like gas stations, vending machines, unplanned bites, etc. are where users feel the most guilt and have the fewest tools to help them.

Vibecoding

I was interested in testing the capabilities of AI tools that would allow me to make a more developed prototype and better understand the technical limitations of my goals.

I used Figma's MCP integration with Cursor to test how the scanner, list logic, and goal balancing would potentially function.
