A quick UX project demonstrating the design process and voice assistance integration as a part of solutions.

Project Overview: 

This is a quick project case study based on Julia, a busy career woman with a young child. She is a coffee lover and needs a quick way to order coffee from her favorite nearby shop so that she can stay motivated and energetic during the day.



Waiting in long lines is miserable and skipping coffee in the morning could ruin her whole day. She wishes there was quick, simple way to order coffee from either her favorite cafe or from a local shop in her neighborhood (she loves to support local businesses!).


Blinki is a mobile app that offers a simple, quick way to order coffee in the blink of any eye from any coffee shop nearby. The key features include:

  • Hands-free ordering by voice assistant

  • One app service from any local coffee shop

  • Shows how many orders are in ahead of you and estimates the pickup time

  • Order from your favorite menu from your favorite shop

  • Instantly search stores nearby

My role: 

To provide mobile solutions for users. My role includes:

  • User & competitor analysis

  • Workflow identification

  • Prototyping

  • Wireframing

  • User interface design

  • Style guide creation

Project time: 2 days


Understanding Users & Competitors:

Competitor Analysis: 

What's out there in the market:


  • Order coffee ahead of time from any local store in the neighborhood

  • Offers promotions and rewards


  • Users need to search for stores and menus

  • No way of knowing how many orders are ahead of you

  • No voice assistant; users need physical interaction with the app

Persona: Julia, a dedicated working mom

About: Julia is a young professional growing in her career while balancing parenthood. She sacrifices for her family and work. She is an energetic, multitasking woman who needs a cup of coffee to power up her day.

"I wish there was an easy way to order a coffee from my favorite store or shop nearby when I need it. I don't have time for long lines."



Getting a favorite coffee every day helps boost her energy and creativity and keeps her focused.

Need & goal:

She wants a quick, easy way to order a coffee no matter how busy she is, where ever she is.

Pain points:

● Waiting in a long line just to get a coffee

● Can't order ahead or plan when to order and pick up

● Unable to find other nearby coffee shops 

● Difficulty interacting with the screen while on the go

What's the user problem?

Problem Statement:

As a dedicated working mom and career woman, Julia needs a quick, convenient solution to order coffee with an estimated pickup time. She doesn't have time to wait in lines, is often on the go, and her hands are always busy. When she misses her morning brew, her busy life could quickly drain her energy and may ruin her day.

Hypothesis Statement:

Creating a coffee network mobile app where users can easily order from any store, view estimated pickup times, create a reminder schedule to place daily orders, and interact with a voice user interface would help save 10-15 minutes that would've been spent waiting in line.
