Bill X
Dice the Bill—Convention of Splitting a Check
Overview
The project, "Splitting a check at a restaurant," is the significance of everyone's assistance in a crisis when a couple of eaters desire a set of equality in their meals.
Bill X provides the separation of the group's orders and the cost owed by the members.
The crucial concept of the design activity was to demonstrate each step of the process to keep track of who has purchased what items and how can each individual owes to the person who will cover the group bill.

UX process
For Bill X, I followed an iterative design process to deeply understand user needs and create a simple, transparent solution. Starting with research and user interviews, I identified key pain points in group bill splitting. Through rapid prototyping, user testing, and refinement, I developed a tool that makes it easy for diners to track and split their shared bills with confidence.
Understanding the Problem
The project aims to develop a more accessible application, and it was designed because the problem is not too known for its solution.
The reason for working on this project was to establish an accession for those who generally need to waste less time on everyone, including servers and the business. Restaurants are a constant business that individuals dine in for celebrations or other events, which is a fast-paced environment.
Desired outcomes for this project are beneficial. It uses the most uncomplicated directions, leading you to a confirmation at the end of the process. Also, a reminder will be sent to your friends, and you do not have to provoke them by disturbing them; it will automatically direct them with a notification on their device.
Target Audience:
The target audience we had in mind while working on the application was friends, families and co-workers aged 18 to 45.
It could be almost anyone who would like to achieve their meals at a restaurant with a group of individuals. The user interaction is occasional, where others come together.
Usually, not everyone meets at a restaurant every day for specific reasons such as celebrations, birthdays, graduations, business meetings, etc.
Therefore, restaurants usually come in a group setting, and it is natural for everyone to discuss affairs depending on their record of having an all-in-one gathering.
Goal:
To design an app that is simple for all users and allows them to track a group's bill to reasonably divide the plans and make it faster to decide whom to take over the check.
Gathering Insights
After collecting informations from user interviews, I conducted a mapping with my teammate to combine the pains identified. This process helped me clearly visualize how users think, feel, and behave during group dining. From this, I noticed key frustrations such as confusion when calculating bills, hesitation in social situations, and the desire for a faster, stress-free solution.
Journey Map
After going through the UX process, I gained a deeper understanding of the key challenges users face when splitting group bills. The empathy map and journey map highlighted common frustrations such as cognitive overload, awkward group dynamics, and delays during payment. These insights reinforced the importance of designing a tool that is simple, transparent, and easy for anyone to use in social dining situations.
Wireframes
I first presented the idea visually through sketches, exploring how the application would guide users through the process. I analyzed several existing applications to understand typical user flows and considered what actions a user would take when first launching the app. One key challenge was designing how group members would owe the individual using the app to pay — ensuring this flow was clear and intuitive. Sharing my sketches with others helped clarify this process.
After conducting a cognitive walkthrough with users, I gathered questions and feedback to identify improvements and gauge satisfaction. I tested the flow with friends who frequently dine out in groups, which provided valuable insights. One major improvement was the suggestion to add a reminder feature, helping users track who owes whom after the meal — a significant finding that influenced the redesign.
Through this process, I learned that both successes and failures play an important role in refining the design and improving the overall user experience.
Final Prototype
I used Figma to create the medium-fidelity prototype, transforming my original sketches into a digital version. During usability testing, users asked questions about the flow and suggested improvements. One important change was redesigning the confirmation page to make it feel more complete and clearly show the split results.
Another key update was changing how tips and taxes are displayed — switching from dollar signs to percentages, based on user feedback. I also simplified the process by combining the payer, item list, and total amounts on one screen, making it easier to review before confirming.
This feedback helped me refine the app into a cleaner, more intuitive experience, as shown in the final prototype. I also learned the importance of preparing well for user testing and how valuable small adjustments can be in improving the design.
