Competitive Audit

In order to construct a concise and solid foundation for Sammy’s Sandwiches, I had to venture out and see what the prominent restaurant applications were already doing and what user goals they were not reaching. I evaluated several features deemed vital from user surveys and identified which ones Sammy’s Sandwiches could capitalize on to have a leg up over other applications.

I found that only two of the four main competitors offered user profiles.. Even then, the user profile feature is incredibly limited and offers very little in terms of order convenience.

Others refuse to offer any sort of loyalty programs or incentives to customers.

Preparing the Journey

Before moving onto high fidelity wireframes and mocks, I wanted to get a feel for what the core of the app would look like when put in front of me. I also wanted to address how a user could expedite their order.

Digital Wireframe

After ideating and drafting some paper wireframes, I created the initial designs Saammy’s Sandwiches app. These designs focused heavily on the user’s journey to convert previous or favourite orders quickly and have less touch points.
To prepare for usability testing, I created a lo-fi prototype that connected user flow creating a profile and re-ordering from an existing account.

These were the main findings uncovered by the usability study:
  • Creating a new profile was frustrating. Wasn’t obvious how to create one
  • People with vision impairments found the icons too small to see and had to zoom in too often
  • App design was uneventful and tone was too robotic
  • Some tasks took too long to complete compared to other apps because the buttons to press were not in obvious places

Mockups 1

Based on the usability study I created a layout consisting of hiearchy by grouping previous orders together and then adding favourite items with CTAs to quickly repeat the order, all within their account screen.
Login and account creation became easier by adding an account button on the upper right corner of the every screen. Icons and buttons were made larger and more prominent.

5 out of 5 total participants said they found this process easy and enjoyable.

“It really helps that I can easily find my previous or favourite orders and 1-click to start the order” — Participant 5

High-fidelity prototype

The high-fidelity prototype followed the same user flow as the lo-fi prototype, including design changes made after the usability study.

Style Guide

Rustic colours were created to portray authentic italian sandwiches. San-serif fonts were included to give a balance of modern design to an otherwise traditional palette.


The tone and design of the app are easy to follow and make the whole experience enjoyable.

Some tasks need to be more obvious for those users who aren’t as computer literate as others.

Next Step 01

I would further enhance the map section to show best route options after checkout when user is picking up an order

Next Step 02

I would need to add a cart button on the header bar for quick access to order

Next Step 03

I would like to add more menu items and choices for even more customer satisfaction
