01 Overview

Tracking calories shouldn't feel
like a second job.

Most nutrition apps overwhelm users with data and underdeliver on guidance. Calorie Wise bridges the gap between awareness and action giving people the tools to understand what they eat, why it matters, and how to improve without obsessing over numbers.

72%
of users abandon nutrition apps within the first two weeks

more likely to reach health goals when using consistent tracking tools
02 The Problem

Overnight we need tracking calorie intake regularly, eating quality, and physical health but getting there is the hard part.

Users know what they should do. The barrier isn't knowledge it's friction. Too many taps, too little context, too much shame built into the experience.

"I want to eat better but I don't have time to manually log everything after every meal. By the time I get around to it, I've forgotten half of what I ate."

User interview participant, 28, working professional

Three problems emerged consistently from research:

Pain Point 01
Manual food logging is time-consuming and tedious. Users abandon the habit when it interrupts their day.
Pain Point 02
Calorie numbers without context don't motivate change. Users feel judged, not guided.
Pain Point 03
Apps fail to adapt to different eating cultures, lifestyles, or flexible goals.
Pain Point 04
No feedback loop. Users don't understand the relationship between their meals and how they feel.
03 Research

Listening before designing.

Conducted 12 user interviews, a survey of 60 respondents, and a competitive audit across 6 leading nutrition apps. We synthesized findings into clear themes.

01
User Interviews
12 in-depth interviews across age groups, dietary goals, and tech comfort levels
02
Survey
60 respondents on current habits, frustrations, and unmet needs in nutrition tracking
03
Competitive Audit
Analyzed MyFitnessPal, Cronometer, Lose It!, Noom, and two emerging apps
04
Affinity Mapping
Synthesized 200+ data points into 6 core themes through collaborative clustering
04 Persona

Designing for one person
means designing for many.

Our primary persona consolidated the most consistent patterns from our research a busy adult who wants to be healthier but has real constraints on time and attention.

Primary Persona

Maya, 29 Marketing Manager

Wants to lose 10 lbs before summer but can't commit to rigid meal plans. Cooks 3 4 times a week, eats out the rest. Tried MyFitnessPal twice, dropped it both times.

Goals
Lose weight gradually · Understand what she eats · Build sustainable habits without obsessing
Frustrations
Too many steps to log a meal · Feels judged by the numbers · App doesn't understand restaurant food
Behaviors
Checks her phone 80+ times/day · Cooks on weekends · Often forgets to log until evening
Needs
Quick logging · Gentle nudges · Progress that feels real · Flexibility for imperfect days
05 How Might We

Turning pain points into
design opportunities.

HMW framing helped reframe every frustration as a solvable design challenge shifting the team from problem-mode to possibility-mode.

HMW 01
How might we make food logging fast enough that users don't skip it when they're busy or distracted?
HMW 02
How might we present calorie data in a way that motivates rather than shames?
HMW 03
How might we help users understand the relationship between what they eat and how they feel?
HMW 04
How might we accommodate diverse eating habits, cuisines, and lifestyle constraints?
06 Journey Map

A day in the life of a user
trying to eat better.

Mapping Maya's day revealed critical moments where the current experience breaks down and where Calorie Wise has a chance to intervene.

Morning Rush Lunch Break Afternoon Snack Dinner Out End of Day
Action Grabs coffee, skips breakfast Orders at desk, eats quickly Vending machine, doesn't log Restaurant, unsure of portions Tries to recall everything she ate
Feeling Rushed Uncertain Guilty Anxious Defeated
Gap No quick log option No restaurant lookup No gentle reminder No portion estimation Opportunity: end-of-day recap
07 Solutions

Four problems.
Four focused answers.

Solution 01

Quick-Log

One-tap food entry with AI-powered suggestions based on time of day, past meals, and location context. Log a meal in under 10 seconds.

Solution 02

Progress Framing

Replace hard calorie limits with a flexible daily "budget" visualized as momentum rewarding streaks and consistency, not perfection.

Solution 03

Smart Nudges

Contextual reminders that know when you've eaten but haven't logged. No shaming just a gentle tap at the right moment.

Solution 04

Meal Intelligence

Restaurant menu scanning and portion estimation using computer vision. Works even when nutritional data isn't provided by the restaurant.

08 Key Features

Features that make
Calorie Wise different.

Barcode + Photo Scan
Instantly identify packaged foods or restaurant meals using the camera. No typing, no scrolling through a database of 8 million items.
Flexible Goals
Set calorie goals by week, not just day. Ate more on Friday? Saturday balances it without guilt or penalty.
Mood + Energy Log
A 5-second check-in connects how users feel to what they ate surfacing patterns most trackers miss entirely.
Weekly Review
A Sunday summary that's honest but encouraging. Highlights wins, flags one area to improve, and sets the tone for the week ahead.
Recipe Builder
Log a home-cooked meal once and save it forever. The app remembers proportions so re-logging takes one tap.
09 Pretotyping

Validating demand before
writing a single line of code.

Calorie Wise fake front door landing page

Before building, we launched a fake landing page to measure real-world interest. The numbers confirmed there was genuine appetite for a better calorie tracking experience.

Insight 1 Mechanical Turk

A drop in sustained
interest over time.

Mechanical Turk engagement charts

The pretotyping phase using Mechanical Turk provided key insights into user interest and engagement. Initially, users showed moderate interest, but this declined over time, along with their energy levels. While the concept initially engaged users, sustaining their interest proved challenging their experience became less positive as time went on. These findings highlight the need for improvements to maintain consistent user engagement.

10 Usability Testing

Moderated tests
with five users.

I conducted moderated usability tests with five users to identify interaction gaps and problem areas within the app. The process yielded valuable insights into certain features, leading to design iterations informed by user feedback.

11 Takeaways

What this project
taught me.

01
Employing a structured approach, such as the Double Diamond Method and the 5 Elements of UX Design, facilitates the development of a well-rounded, user-centric product.
02
Prioritizing features using methods such as the KANO model and the MoSCoW methodology ensures the development of a streamlined and effective product that addresses users' most critical needs.
03
Conducting comprehensive usability testing and pretotyping during the design process is crucial for refining the prototype and ensuring its functionality and user-friendliness.
12 Final UI

From wireframe to
a living product.

Every screen went through multiple iterations shaped by research, usability feedback, and a relentless focus on reducing friction. The final UI is clean, warm, and built around the user's daily rhythm rather than rigid tracking rules.

Statistics Dashboard
A single-glance overview of calories remaining, macros, and daily progress designed to inform without overwhelming. The donut chart anchors the screen with one clear number.
Recipe Unlock System
Users earn points for consistent logging, unlocking curated recipes from global cuisines. Gamification as motivation not pressure.
Meal Log by Category
Breakfast, Lunch, Snacks, and Dinner each have their own entry point with calorie targets. Adding a meal is always one tap away.

13 Reflection

What this project
taught me.

Calorie Wise pushed me to think carefully about the emotional weight of health products. Every design decision either added to someone's anxiety or reduced it. There's no neutral choice when the subject is someone's body.

The biggest shift: moving from "how do we track more?" to "how do we make users feel capable?" That reframe changed everything the visual language, the copy tone, the onboarding, the feedback loops.

The next step is integrating with HealthKit and Google Fit, and running a longer retention study over 90 days. The design is ready. The question is whether the habit sticks.
