Expenseo leverages modern cloud technologies to deliver a seamless experience in managing personal finances. The app listens for incoming bank email notifications, processes the transaction details, and updates the user's financial data in real-time.

Expenseo listens for incoming Gmail notifications related to bank transactions. Using AWS Lambda, the app processes these emails and extracts transaction details, which are then stored in Amazon DynamoDB.

A flexible and efficient GraphQL API, powered by AWS AppSync, allows users to manage transactions and query their financial data easily.

A native iOS app built with SwiftUI displays the user's transaction data in an intuitive and visually appealing interface. Users can view, update, and manage their transactions effortlessly.
