Accounteer makes use of many of the features of iOS5, including iCloud. Some users may not want or be unable to upgrade to iOS5, and so Budgeteer was developed as a new app.
You can override the currency Accounteer uses from the settings screen.
Accounteer can export a report for printing, or a tab delimited file to import into a spreadsheet.
You can disable a category from the settings screen. You cannot delete a category as it may have expenses booked against it.
There are a number of things you can try. See the Accounteer iCloud help page to try and determine the problem.
