Real-Time Expense Tracker for Individuals & Families
Problem
A growing family-focused fintech startup needed a mobile solution for collaborative expense tracking, AI-powered budgeting, and real-time alerts. Existing apps were too complex or lacked family sharing features.
Challenge
Build an intuitive, multi-user mobile app that enables real-time, collaborative budgeting for families, with seamless data sync and actionable insights.
Solution
Megicode partnered with the client to design a React Native app supporting both iOS and Android. We integrated Supabase for real-time data sync, built ML-driven budget forecasting, and implemented notifications for overspending. The UI was tailored for multi-user (family) scenarios, with intuitive category tagging and a shared dashboard.
Impact
The app reached 1,200+ beta installs in the first quarter. 85% of users reported improved budget awareness. Family sharing and AI insights were the most-used features. App Store rating: 4.7/5.
Implementation
The app was developed over 8 weeks, with continuous feedback from beta users. Key milestones included the launch of the family dashboard, successful real-time data sync tests, and the integration of AI-driven insights.
