Olyo

Designing a seamless way to split group travel expenses

I was responsible for ux research, mapping user flows and designing the UX/UI of the app. My work included translating insights into wireframes and prototypes, shaping both the structure and the visual identity of the product.

Olyo transforms the stressful process of cost sharing into something simple and seamless. It’s not just an expense tracker — it’s a tool for happier, more harmonious group travel.

PROJECT OVERVIEW

Olyo is an AI-powered travel expense splitter — a mobile-first app designed to make group trips easier by transforming messy receipts into clean, shareable summaries.

The goal was to create a seamless, stress-free way for travelers to track shared costs in real time, ensuring fairness and transparency for everyone involved.

The goal was to create a seamless, stress-free way for travelers to track shared costs in real time, ensuring fairness and transparency for everyone involved.

During group trips, tracking shared expenses often turns chaotic. People lose receipts, forget who paid what, or feel awkward discussing money. Someone always ends up paying more, someone less — and in the end, the confusion overshadows the fun.

This led to a simple but important question:

How might we help travelers keep track of their expenses in real time and split them fairly, so everyone can relax and enjoy the trip?

An intelligent expense-sharing app that takes the stress out of settling costs.

Each traveler uploads their receipts – and Olyo’s AI does the rest:

  • Scans and itemizes expenses, including tips
  • Categorizes and records each transaction
  • Keeps everyone updated instantly
No awkward math, no forgotten payments — just clarity, fairness, and peace of mind. With Olyo, group travel becomes about memories, not money.

Research

The analysis revealed that while there are both general and travel-focused expense-sharing apps available, none of them provide a complete, travel-first experience that truly covers every traveler’s need.
Examining the main players showed a recurring pattern: most applications focus on the core functions of expense splitting — such as receipt scanning and balance tracking. Although some solutions are designed specifically for travelers, they often fall short in the areas that matter most in real travel contexts: offline functionality, multi-currency and multilingual support, and a clear, easy-to-use interface.

I conducted interviews with 10+ participants to uncover the real challenges behind splitting expenses.
In-depth user conversations helped confirm my initial assumptions and provided deeper insight into how travelers manage shared expenses during group trips — what tools they use, and where they typically run into problems.

According to participants, tracking expenses while traveling is never easy. They try to keep receipts, make mental notes, or track who paid what — but in the excitement of the trip, things quickly get forgotten. Once home, it all turns into post-trip math and confusion, as they try to piece everything together.

Once home, it all turns into post-trip math and confusion, as they try to piece everything together.

The biggest challenge during group trips is that it’s almost impossible to keep accurate track of shared expenses.

Since everyone pays for different things — sometimes one person, sometimes another — by the end, no one really knows who spent how much. This isn’t just caused by missing receipts or forgotten amounts, but also by the fact that spending habits vary widely between people at meals, activities, or events. As a result, the final settlement often feels chaotic and unfair for everyone involved.

If we can’t track who paid what, it becomes impossible to split expenses fairly.

Additional Key Findings
Fair splitting is difficult
Dividing bills equally often feels unfair when individual spending differs significantly — this creates tension and frustration within the group.
Multiple currencies cause confusion

When a trip involves several different currencies, the constant conversions add unnecessary complexity and often lead to mistakes.

Sara

21, Student

Sara’s main goal is to make sure that expenses are split fairly based on actual consumption, not just evenly divided. She wants to track spending in real time during the trip to avoid unpleasant surprises or unnecessary tension afterward.

David

32, Lawyer

David doesn’t want expense tracking to become an extra burden. He’s not overly worried about every penny balancing out — he believes it evens out over time. For him, the key is clarity and transparency during the trip, so he doesn’t have to deal with complicated calculations after the trip.

Through feature prioritization, I identified which elements are essential for usability, which enhance the overall user experience, and which can provide added value over time.

To organize the features, I applied two methods:

  • The MoSCoW framework, which categorizes features based on their importance and necessity.
  • The Impact–Effort matrix, which balances user value against implementation difficulty. 

This process helped reveal which features would deliver quick wins and which would require long-term investment for greater user benefit.

AI in Olyo isn’t just an extra convenience — it’s the key to fast, accurate, and user-friendly expense sharing.
Artificial intelligence supports the app where manual processes would otherwise be slow or error-prone, making the experience not only smoother but also more reliable.
Receipt Scanning & Text Recognition → Fast and Error-Free Data Entry

AI automatically detects the contents of receipts — items, prices, taxes, tips, and currencies — ensuring quick and accurate data input.

Itemized Splitting → Fair Expense Distribution

AI can assign individual items to people, calculate proportional tips, and handle spending differences, ensuring a fair and transparent split.

Categorization & Tagging → Organized and Clear Expenses

AI suggests categories (e.g., food, transport, accommodation), helping users keep their trip expenses structured and easy to review.

Error Detection & Trust → Accuracy in Settlements

AI flags inconsistent or uncertain data, provides explanations, and increases transparency — helping build trust within the group.

The final product

Users can easily set up a new group trip, define the base currency, and customize expense-sharing preferences — all within a clean, intuitive flow.

The invitation process is quick and flexible, letting users invite friends via link, QR code, or by entering a unique trip code in the app.

When scanning a receipt, the app automatically detects key details and evenly splits the total amount among all members for effortless balance tracking.

When scanning a receipt, users can assign each item to specific members, making it easy to split costs accurately based on what everyone ordered. The app highlights any unassigned items and lets other participants review and confirm their share later.

Designing for collaboration means designing for trust

Throughout this project, I learned that expense tracking isn’t only about numbers — it’s about people feeling confident that everything is fair and transparent. The biggest challenge was finding a balance between automation and control: making the AI smart enough to simplify tasks, yet leaving room for users to stay in charge. This insight shaped my approach to the final design — one that prioritizes clarity, shared understanding, and a sense of ease within group interactions.
