AI-Powered Expense Tracker That Makes Financial Management Effortless
AI-Powered Expense Tracker That Makes Financial Management Effortless
Lumispend is an intelligent expense tracking application that eliminates the friction of manual data entry through AI-powered voice recognition and receipt scanning, making financial management truly effortless.
Lumispend is a personal finance app that tracks expenses and income with unprecedented ease. Using AI technology, users can add transactions via voice commands or by simply scanning receipts, removing the tedious manual entry that makes people abandon expense trackers.
Most expense tracker apps fail because they require too much effort from users. Every transaction means stopping what you're doing to manually type details. This friction causes abandonment. Lumispend solves this with AI-powered input methods that take seconds, not minutes.
As the Product Designer and Developer, I handled the complete product lifecycle from user research and interface design to building the mobile app with React Native and integrating AI features for voice recognition and OCR receipt scanning.
Strategic objectives focused on removing friction and making expense tracking a habit, not a chore.
Design input methods that take seconds, not minutes. Voice entry and receipt scanning should feel faster than buying the item itself.
Create an experience so smooth and rewarding that users actually want to track expenses rather than avoiding it.
Transform raw data into clear, visual insights that help users understand and improve their spending patterns.
Offer both light and dark modes to ensure comfortable use in any lighting condition, day or night.
A user-centered approach from problem discovery to solution implementation.
Why do people abandon expense tracker apps?
AI-powered input that makes tracking effortless:
Understanding our primary users through detailed research and interviews.
Deep dive into understanding our user's thoughts, feelings, and daily experiences with money.

The game-changing feature that makes Lumispend different. Simply speak your transaction naturally — "I spent 5000 naira on groceries at Shoprite today" — and AI extracts amount, category, merchant, and date automatically. The system processes your voice, validates the data, then presents a pre-filled form for quick confirmation. No typing required.
Turn paper receipts into digital records instantly. Point your camera at any receipt and OCR technology extracts merchant name, purchase amount, date, and even individual items. Perfect for post-shopping logging without manual typing. The AI automatically categorizes based on merchant recognition.
View your spending history two ways. Detailed List shows every transaction with category icons, amounts (color-coded red for expenses, green for income), and timestamps. Calendar View displays a monthly calendar with date highlighting — pink for expenses, blue for income, yellow for mixed days. Tap any date to see that day's transactions below.
Home screen displays category chips (Food, Transport, Shopping, etc.) at the top. Tap any category to instantly filter all transactions. The balance card shows current balance, total expenses, and income at a glance. Budget progress bars visualize monthly spending limits with percentage indicators.
Full light and dark mode support with beautiful gradient accents that work in both themes. Dark mode features the signature pink-to-purple gradient against deep backgrounds, perfect for late-night expense logging. Light mode offers a clean, professional look for daytime use. Switch instantly in settings.
High-fidelity screens in both light and dark modes.
Building a product that people actually want to use every day.
The biggest insight from designing Lumispend was understanding that people don't hate tracking expenses — they hate the work it requires. The solution wasn't better charts or fancier analytics — it was making input so fast it feels invisible.
Voice entry and receipt scanning aren't just "nice features" — they're fundamental to solving the abandonment problem. When logging a transaction takes 5 seconds instead of 30, users actually do it. When the app extracts data automatically instead of forcing multiple form fields, it respects people's time.
Building the AI integration taught me the importance of graceful error handling. The key was designing the confirmation step — letting AI do the heavy lifting but always giving users a chance to review and correct before saving. This balance between automation and control is crucial for trust.
Looking forward, I want to explore predictive features — using transaction patterns to automatically suggest budgets, warn about unusual spending, and forecast month-end balances.
Let's discuss how I design products that eliminate friction and create delightful user experiences.
