Stat is the ultimate app designed to simplify users' access to short-notice appointments for COVID-19 tests and vaccines. Stat provides users with up-to-the-minute information on COVID-19 test and vaccine availability in their area, so they can find care, fast.


How it started.

In addition to the COVID-19 virus, the emergence of the pandemic caused an outbreak of fear and concern. This resulted in a need for COVID-19 tests and vaccines, which were extremely difficult to come by.

define Problem

There isn't a product on the market that offers a localized view of same-day or next-day COVID-19 tests and vaccines.

Currently, individuals are haphazardly searching for COVID-19 tests and vaccines due to high-demand, little time for preparation, and lack of options.

define Goal

Improve users' experience discovering and booking nearby COVID-19 tests and vaccines.

Users require a self-service app that displays available COVID-19 tests and vaccines at nearby health care facilities.

How might we...

Make COVID-19 testing and vaccinations easily discoverable to locals?

Improve users' experience searching for short-notice COVID-19 testing and vaccinations?

Simplify the booking process for individuals and their loved ones?


Understand users to begin crafting a user-centered experience.

To uncover users' frustrations and feelings around the search for COVID-19 tests and vaccines, I interviewed a user group of 10 participants ranging from 18 to 55 years old. Participants resided in metropolitan and suburban areas.



stated their biggest motivator to get tested and/or vaccinated is their family.

The worried mother

A priority for Gisella is her and her family's health. Gisella and her husband have a 6-year-old son and 10-year-old daughter who mean the world to them. Their goal is to make sure their children live healthy lives.

Gisella recently found out children are susceptible to COVID-19. She disinfected her home and began teaching her children about personal hygiene. They all wear masks when they leave the house, but she still doesn't feel safe.


The health enthusiast

Gabriel considers himself a fitness buff. He loves most forms of exercise, especially aerobic exercises. He believes in looking good, but most importantly feeling good.

Gabriel has a family history of heart issues. He's aware COVID-19 can cause secondary heart-related complications. This makes him extremely worried.


The social butterfly

Melissa loves to be with friends, even if it's just a wine and movie night. She's naturally friendly and very social.

Most establishments require proof of vaccination to enter. Many public events require the same proof or a recent COVID-19 test with a negative result. Because of this, Melissa is in need of continuous testing or a vaccination.


Use research to inform ideation.

After understanding individuals' frustrations around booking last-minute COVID-19 tests and vaccinations, the next step was to develop ideas around a self-service app that would meet their expectations. The sketches evolved into digital wireframes, which eventually became the low-fidelity prototype.





How functional is it?

After nailing down the wireframes, a low-fidelity, or lo-fi, prototype was rendered. The purpose of the lo-fi prototype was to explore how a product will function and how a user will move through the flow, without having to design every detail.

Test & modify.

By conducting moderated usability studies, I assessed how easy or difficult it was for users to complete core tasks. The data from the usability studies was used to create an affinity diagram.

Organize my findings.

To begin analyzing the data, an affinity diagram was used to organize my findings into common themes.

Lo-fi prototype

Let's improve it.

The themes evolved into insights, which drove action and improvements to the overall user experience of Stat.


Users need an intuitive feature when selecting who the visit is for.

The left-to-right swiping function confused most users when selecting who the visit was for.


Listed family members

It wasn't clear to users that they needed to swipe. The design was modified so users could easily select a family member from a list, instead of swiping.


Users should see available visits in a list format instead of on a calendar.

Users were shown a seven-day calendar, despite only seeing appointments for that day or the follow day—causing confusion.


Listed time slots

Because Stat focuses on same-day and next-day visits, displaying a seven-day calendar was redundant. The calendar feature was removed entirely.


Users need a simpler way of selecting a COVID-19 test vs a vaccine.

Several users accidentally selected the wrong one and needed to start their search over.


Toggle button

The original design required the user to select a COVID-19 test or vaccine from a drop-down. This was revised to include a toggle button instead, eliminating an unnecessary step and simplifying the user flow.
