For this project, I was tasked with developing a coffee app for a seaside café. To simplify the project, the store only sold three drinks: Brewed, Espresso, and Cappuccino, - but allowed for extensive customizations. To successfully finish this project, I needed to create a comprehensive prototype that incorporated multiple user flows based on thorough user research and testing.

To start off this project, I began by sketching out initial screen designs and mapping out the user flow. Additionally, I conducted interviews with four potential users to understand their preferences for a coffee app, with a particular focus on drink customization.

To most people, drink customizations are essential. Here is what I gathered:

Participants Requested:

• Plentiful Customizations: Different milk types, sweeteners, temperatures, and add-ons.

• Exact Amounts: Users wanted to customize the volumes of ingredients.

• Easy Reorder – Users wanted an efficient way to reorder their drinks.

• Payment Made Easy – Users wanted to scan gift card or credit cards for easier payment.

Once I gathered input from potential users, I started with the initial design process.

To begin the design process, I created quick sketches of the potential user experience, utilizing insights from the interviews.

For my design, I aimed to create a playful aesthetic. To achieve this, I illustrated unique icons for all customization options in the app.

After finishing my initial designs, I held usability tests with 6 potential users. Utilizing feedback from the tests, I started work on my final designs.
