Splitwit.app

Share costs, not the stress. Splitwit makes sharing expenses effortless.

Overview

Track group expenses, split bills fairly, and settle up with friends—whether you're travelling, living together, or simply splitting dinner.

Tech Stack

  • Frontend: React Native (iOS & Android)
  • Backend: Node.js, Express, PostgreSQL
  • Offline Support: WatermelonDB

The Problem

Existing bill-splitting apps often require constant internet connectivity, are bloated with ads, or have confusing interfaces that make settling complex group debts a headache.

The Solution

I developed Splitwit with an offline-first architecture. You can add expenses while hiking in remote areas or travelling abroad without a data plan. Once reconnected, the app seamlessly syncs with the server. The algorithm automatically calculates the most efficient way to settle all debts (minimizing the total number of transactions).
