Multi-Currency Support

​

Overview

Money Tracker provides native support for multiple currencies, allowing you to track transactions across different countries and currencies without manual conversion. Each transaction stores its original currency, and you can filter and analyze by specific currencies.

​

Supported Currencies

Money Tracker supports these currencies out of the box:

​

How Currencies Work

​

Transaction-Level Currency

Each transaction stores:

• Original amount: The exact value in the transaction
• Currency code: 3-letter ISO 4217 code (USD, EUR, etc.)

This approach preserves the integrity of your financial data without lossy conversions.

​

Example

If you have transactions in multiple currencies:

• $100 USD lunch in New York
• €80 EUR dinner in Paris
• $500 ARS groceries in Buenos Aires

Each transaction retains its original currency and amount.

​

Currency Detection

When transactions are automatically extracted from emails, the AI:

1. Looks for explicit currency codes: USD, EUR, ARS, etc.
2. Identifies currency symbols: $, €, £, and converts to ISO codes
3. Uses context clues: Email language, sender domain, country-specific formatting

​

Working with Multiple Currencies

​

Filtering by Currency

On the Transactions page:

1. Click the Currency filter dropdown
2. Select a specific currency (or “All” to see everything)
3. The transaction list updates to show only that currency

​

Manual Currency Selection

When adding transactions manually:

1. Select currency from the dropdown (shows symbol + code)
2. Enter amount in that currency
3. Transaction is saved with selected currency

​

Document Upload

When uploading receipts or invoices:

• The AI automatically detects the currency from the document
• No manual selection needed

​

Currency Display

​

Transaction List

Transactions display with:

• Currency symbol: $ € £ etc.
• Amount: Formatted with 2 decimal places
• Currency code: 3-letter code (USD, EUR)

Example: $ 49.99 USD

​

Transaction Detail

The detail panel shows:

• Full currency name (United States Dollar)
• Currency code (USD)
• Formatted amount with symbol

​

Currency Formatting

Money Tracker applies locale-appropriate formatting:

​

Multi-Currency Analytics

​

Metrics Dashboard

The Metrics page includes a Currency Comparison card that shows:

• Transaction count by currency
• Total amounts per currency
• Percentage breakdown

This helps you understand your spending patterns across currencies.

​

Subscriptions by Currency

The Subscriptions page groups recurring transactions by currency, showing:

• Average amount in original currency
• Occurrences count
• Next estimated payment date

​

Currency Conversion

Transactions are stored and displayed in their original currencies. If you need aggregated totals across currencies, you’ll need to:

1. Export transaction data
2. Apply exchange rates manually
3. Calculate totals in your preferred base currency

​

Future Enhancement

Automatic currency conversion with real-time exchange rates is planned for a future release.

​

Best Practices

1. Let the AI detect currency: When possible, rely on automatic extraction rather than manual entry
2. Keep receipts: Upload receipts for accurate currency documentation
3. Filter by currency: Analyze spending patterns per currency separately
4. Use consistent accounts: Connect Gmail accounts specific to each currency region
5. Review AI extractions: Verify currency was correctly detected, especially for ambiguous symbols

​

Common Currency Scenarios

​

Travel Expenses

If you travel and spend in different currencies:

• Each transaction captures the local currency
• Use date range filters to analyze spending during your trip
• Filter by currency to see all expenses in that region

​

International Subscriptions

For subscriptions billed in foreign currencies:

• The AI detects recurring charges in the original currency
• Subscription tracking works per-currency
• No conversion confusion

​

Multiple Gmail Accounts

If you have Gmail accounts in different countries:

• Each account’s transactions retain their local currency
• Use email filters to see transactions by account/currency
• Dashboard shows totals per currency

​

Currency Validation

​

On Manual Entry

The app validates:

• Currency must be selected from the dropdown (no free text)
• Amount must be a positive number
• Maximum 2 decimal places for most currencies
• CLP and COP typically have no decimals (integer values)

​

On AI Extraction

The AI ensures:

• Currency is a valid 3-letter ISO code
• If currency is ambiguous, defaults to USD or uses context
• Invalid currencies are flagged for manual review

​

Troubleshooting

​

Wrong Currency Detected

1. Edit the transaction
2. Select the correct currency from the dropdown
3. Verify the amount is correct for that currency
4. Save changes

​

Missing Currency Symbol

If a currency displays without a symbol:

• The currency code (USD, EUR) is always shown
• Symbol mapping may be missing for rare currencies
• Functionality is not affected

​

Currency Filter Not Working

If filtering by currency doesn’t show expected results:

• Check that transactions actually exist in that currency
• Verify the currency code matches (e.g., USD vs. US$)
• Clear all other filters to isolate the currency filter
