## Overview

MoneyMatev2 appears to be an Android personal-finance app. Its likely user flow is entering or scanning a transaction, then reviewing spending and budgets; the tree also shows account, category, recurring-transaction, reminder, security, statistics, and sync features. The README provides no capability or wiring details, and no runtime source was excerpted, so relationships below are dashed and unverified rather than asserted as inspected calls.
