SapientNitro challenged our team to envision a new food delivery, shopping, preparation, or consumption service that leverages data from separate service ecosystems into our own service or platform.

This project was advised by Jodi Forlizzi and Leanne Libert.


Why don't patients change their diets?

Health complications can be remedied by changes in diet, and patients only see their doctor yearly for check-ups.

After a trip to the office, there is nothing holding patients accountable to change their eating habits.


Digestible tracks and syncs patients' grocery and restaurants receipts with their electronic health records for their doctor's viewing. The app keeps doctors in the loop year-round for health and keeps patients accountable for their diets.


Doctors, Patients, and Food Providers Benefit From Sharing Data


Patient engagement usually ends at the office doors, and it is difficult to make proper decisions and recommendations with a lack of data.


It is easy to start life changes, but many times, people fall off the bandwagon without continued motivation or a way to track progress.

How It Works

Digestible records food-purchasing behavior via grocery and restaurant receipts updates to their electronic health record found at the doctor's office. According to the diet guidelines set by the doctor, the app provides small recommendations for food substitutions.

View Receipts

Patients can view their past purchases and see the nutritional content of each item by browsing and sorting through receipts.

These receipts are automatically updated after transactions are made.

Get Recommendations

Digestible suggests small changes, like choosing low-sodium frozen corn over canned corn.

Small steps to a healthier diet are less deterring than suggesting broccoli over a bag of chips.

Connect With Doctor

Patients and doctors can interact year-round instead of only at yearly appointments.

This provides motivation to patients and helps improve the relationship between users.

Design + Research Process

Pivoting Ideas

Our team's original goal was to tackle the issue of childhood obesity, but through our research process, we learned that it was a hard one to solve. However, we recognized the relationships people have with food and how that affects health.


Brainstorming With Concept Map

We started ideating with a concept map revolving around food, outlining the areas of availability, affordability, quality, and convenience.


Speed Dating Storyboards At Grocery Stores

We storyboarded and speed dated online via surveys distributed on Reddit and in-person with individuals outside of two Pittsburgh grocery stores to get their thoughts. Our team decided to focus on the themes of access and knowledge.

At this point, we decided to temporarily explore and broaden our scope to "help people eat better".


User Enactment Revealed Impulse Purchases

Speed dating results rated the ideas of grocery store pre-labeling and receipt health scores highest in need and usefulness, so our team performed a user enactment to test these two ideas.

The enactment helped us remember that shoppers make impulse buys. The shopper commented that the shock appeal of a grocery health score might wear out after the first few purchases.


Designing the User Flow

We learned that the strength of our app was in providing users with recommendations of healthy alternatives, and not in displaying data.

Behavior is hard to change--it's difficult to tell someone to give up chips and eat broccoli instead. Because of this, we demonstrated less dramatic changes like the substitution of frozen corn for canned corn, which is an easy change for a low-sodium diet.

Future Work

Exploring Solutions Outside of Technology

From interviews, we learned that there are still many people who suffer from health complications but do not own smartphones or computers. I would like to see how we can help this segment of individuals get the information to improve their diets.
