Smart Expense Tracking Made Simple
Minty is a powerful, privacy-focused expense tracker that automatically reads and categorizes your transaction SMS messages. Built with React Native for a seamless mobile experience on Android, Minty turns the tedious task of expense tracking into an effortless, automated process.
The Problem It Solves
In India, every UPI transaction, credit card payment, and bank transfer triggers an SMS notification. These messages contain valuable financial data, but manually tracking them is time-consuming and error-prone. Minty solves this by automatically parsing these SMS messages, extracting transaction details, and organizing them into a comprehensive expense tracking system, all while keeping your data completely private and offline.

Privacy-First Philosophy
In an era where fintech apps demand bank account access and send your data to the cloud, Minty takes a different approach. Your financial data is sensitive and personal, it should never leave your device. Minty processes everything locally on your phone, stores data in a local SQLite database, and requires no internet connection to function.
This is expense tracking reimagined: smart, automatic, and completely private.
