About Splita

A small, focused tool for splitting shared expenses.

Splita is a lightweight web app for splitting shared expenses in a group — built for the moments when you and your friends just need to track who paid for what, without anyone having to download an app or sign up for an account.

Why Splita exists

Most expense-splitting apps assume everyone in the group will install software, create an account, and learn a new interface. That works for some groups. But for one-off trips, casual dinners, or short collaborations, asking everyone to sign up is too much friction.

Splita takes a different approach: one person creates a group, gets a shareable link, and sends it to the rest. Everyone who opens the link can add expenses, view balances, and see who owes whom. No download, no login, no account.

What Splita does well

• No sign-up. Create a group in seconds. Share a link. Done.
• Trilingual. Splita works in English, Japanese, and Chinese, designed for people who live across languages.
• One currency per group. Choose JPY, USD, EUR, GBP, CNY, or KRW when creating a group. Expenses, balances, settlement suggestions, and CSV exports then stay in that currency.
• Mobile-first. The interface is designed to work well on phones, because that's where most expense-splitting actually happens.
• Single-link collaboration. Anyone with the link can edit. No permission systems, no roles, no friction.

What Splita is not

Splita is not a bank, a payment processor, or a financial service. It does not move money. It is a tool for tracking expenses and showing settlement suggestions — the actual transfers happen between you and your group members directly, however you prefer.

Who built it

Splita is built and maintained by Weishi Wang, an independent product builder based in Japan with a background in digital transformation, AI, and product work. The project started from a simple personal need — splitting expenses on a group trip — and grew through continued use by friends and their networks.
