Splity makes shared money simple. Friends, families, flatmates, and teams use it to split bills, track group spending, send money, and ask to be paid back.
Devnori designed the product with the client. It brings payments, a digital wallet, expense tracking, and paid membership plans together in one mobile app.
The challenge
Sharing costs with other people gets messy fast. Someone pays for dinner, someone else buys the tickets, and soon nobody remembers who owes what.
People end up doing sums by hand, keeping notes in a spreadsheet, or paying each other through different apps. It is slow, and it causes awkward conversations.
The client wanted an app that makes this easy while keeping everything transparent. It had to handle bill splitting, direct payments between people, group expenses, and a subscription plan.
The hard part was fitting real financial features into an app that still feels light and simple for everyday use.
What we built
We designed a mobile-first money app. Users can pay someone instantly, split a bill with a group, ask for money back, and see all their activity in one dashboard.
Digital wallet
Check your balance, add money, withdraw, and see every transaction in one place.
Group expenses
Create a group, add people, record what was spent, and let the app work out who owes whom.
Bill splitting
Split evenly, by percentage, by shares, or set custom amounts for each person.
Send money
Transfer funds to another user instantly and securely.
Payment requests
Ask someone to pay you back and see which requests are still unpaid.
QR payments
Scan a code to pay quickly, without typing details.
Transaction history
Every payment, expense, and transfer is listed and searchable.
Contacts
Keep the people you pay most often close at hand.
Premium plans
Extra features are available through a paid subscription.
Security
Safe sign-in, account controls, and payment method management.
Design approach
Money apps often feel heavy. Too many numbers, too many screens, and it is never clear whether a payment actually went through.
We took the opposite path. Navigation is simple. Every transaction shows its status in plain words. Payment journeys guide the user step by step, so nobody has to guess what happens next.
The visual design is built to feel trustworthy, because people need confidence before they move their own money. A shared design system keeps every screen consistent, and we designed with accessibility in mind so the app works for as many people as possible.
Architecture and delivery
The app is built from separate modules, so features can grow without disturbing the rest.
The main parts are sign-up and onboarding, the digital wallet, person-to-person payments, payment requests, group expenses, the bill splitting engine, QR payments, contacts, subscriptions, notifications, security controls, transaction reports, and an analytics dashboard.
The structure was designed to keep the speed and security that people expect from a financial product as the number of users grows.

Conclusion

By combining expense management, payments, a wallet, and subscriptions in one clear app, the platform gives people control over both personal and shared money. Devnori provided the product thinking and design behind it.
