Spleck: Simplify Shared Expenses

A 4-week UX design and research passion project using Adobe Illustrator and Figma. Spleck streamlines sharing expenses among friends and family, eliminating the "who owes who" headache. This mobile app allows users to effortlessly split restaurant bills, including tax and tip, and facilitates seamless in-app payments.



Research is always the first step in my design process. I do a full spectrum competitor analysis, looking at their user flows and seeing what does and doesn't work for them. 

In terms of the problem at hand and what I'm solving for: 

While a common rule of thumb is that, unless discussed ahead of time, diners should expect to split a tab equally, research suggests most diners don't actually do this in practice. In fact, two-thirds of those surveyed do not split the bill evenly when dining out with friends. 

The increasing use of smartphones across the world has provided potential growth opportunities for bill splitting apps.

An estimated 46% Growth in this app industry, based on global need.

Competitor Analysis

During the research process of designing this app, I looked at Venmo and Cash app as they are two examples of leaders in this category.

Cash App & Venmo

Both Cash App and Venmo are very popular peer-to-peer payment apps. They offer similar features and functionality, but they have different strengths and weaknesses. Cash App is generally considered to be more convenient and easy to use, while Venmo is more social and has more features for businesses.

How Spleck differentiates itself from Cash App and Venmo:

Spleck focuses on the specific needs of users who need to split bills and delegate tasks. Spleck offers features such as:

In terms of potential business need:

Target Audience

Designed for those who frequently dine out with groups, simplifying bill splitting and avoiding manual calculations.

Key Features

- Bill Calculator: Automates bill splitting based on user input.

- Itemized Orders: Allows users to specify individual orders.

- Flexible Splitting Options: Offers various splitting methods.

- Payment Integration: Facilitates secure, in-app payments.

- Group Management: Streamlines expense tracking for different social circles.

- Receipt Management: Enables easy expense tracking through receipt uploads.

Design Considerations

- User-Friendly Interface: Prioritized an intuitive design for all users.

- Accessibility: Ensured inclusivity for individuals with disabilities.

- Branding: Created a consistent and recognizable brand identity.

- Responsive Design: Ensured compatibility across different devices.

- Security: Implemented robust security measures such as use of biometrics (fingerprint, face ID)

Things I Tried That Didn't Work

- Implementing an elaborate group management feature, which added complexity without significant benefit.

- Overly elaborate branding, causing a distracting visual clutter.

Using color psychology to boost user engagement in Spleck

- I came to the realization that steering clear of red in the context of users sending money is vital. Red, often associated with warnings or penalties, might inadvertently deter users from sending funds as freely as we'd like them to. To ensure that users remain engaged with our app and continue sending money, I explored the possibility of offering alternative color options. This step can play a pivotal role in incentivizing users and enhancing their experience with Spleck.


What I Did Wrong

- Initially, the user interface lacked clarity, leading to confusion during testing.

- Overemphasized complex splitting options, overwhelming users.

The bottom line

Spleck simplifies the process of splitting restaurant bills for groups, saving time and reducing the hassle of manual calculations. With an improved interface and user-centered approach, it's a practical solution for shared expenses.
