33CmHub vs Bulyvo

33CmHub is an expense-tracking application designed for managing personal income and expenditures, currency exchanges, and multi-currency accounts. The app features five main sections: Overview, Transactions, Currency Exchange, Analytics, and Management. For each entry, the original currency amount is preserved; users can manually input an exchange rate to calculate the equivalent value in their base currency. Transactions awaiting conversion still affect the original currency balance, and reports clearly highlight any records that have not yet been converted. The currency exchange function links the outgoing amount, the incoming amount, and any associated fees, ensuring that the principal amount is not categorized as an expense. Historical exchange rates are managed separately from the rates used for balance conversion; bulk conversions require a preview before confirmation, and all modifications to records remain traceable. The application supports account archiving, customizable currency precision settings, various data visualizations (bar charts, donut charts, line graphs, and area charts), theme switching, a privacy lock, and local backup and restoration. All monetary calculations utilize decimal arithmetic with consistent rounding rules. Data is stored locally on the device, and the codebase is structured by functional modules to facilitate readability, ongoing maintenance, and future expansion.

Bulyvo is an application designed for tracking expenses, managing credit bills, and scheduling payments. Its overview dashboard provides a consolidated view of the current month’s spending, available funds, and outstanding balances. Transaction records are categorized by type, ensuring that repayments are not erroneously counted as new expenses. The bill management feature supports billing cycle adjustments, reconciliation of actual amounts, snapshot confirmation, and installment payments; any modifications to transaction details trigger a prompt for re-verification. Analytical tools—including bar charts, donut charts, and area charts—visualize spending and cash outflows, with options to toggle how refunds are accounted for. Users can attach receipts to entries via their camera or photo library, manage accounts, categories, and themes, set up privacy locks, and export data as local backups or spreadsheet files. When an account is archived, its transaction history is preserved, along with any remaining balances resulting from overpayments or refunds.
