MoneyWise Pro supports multiple currencies and does currency conversions.
Budget periods can be set up weekly, biweekly and monthly, and reports like expenses by budget category or expenses over time can be filtered to show just the data you want to see. MoneyWise Pro lets you define transactions by tag as well as categories, set up recurring transactions and transfer funds between accounts.
You can try the free version of MoneyWise or MoneyWise.eu before buying Pro, with some limits and no currency conversion in the free app. If you decide to upgrade, your data will import into the Pro version. Developed by Handy North.
