From the developer:
If you use Intuit Quickbooks but your online banking exports to the common Quicken (pre-2004 'QIF') text format, you can use Quiff to convert your transactions for import.
Quiff presents a familiar register-style preview of your data, but does not create or edit financial data; it is not a replacement for financial management programs nor does it convert ‘native’ data files.
You may want to check out more Mac applications, such as Personal Finance, Putler or Investors Toolbox, which might be similar to Quiff.
