Cash Expenses is a smartphone app that helps you track your daily cash expenses. Use this app to manually enter in your expenditures.
All your expenditure data is saved only on your phone. No sign up required. No Internet connection required. Ad free.
Customize spending categories anyway you like. And you'll get reports of your monthly spending by category.
The expense database can be exported to Quicken, GnuCash, and Excel in QIF (Quicken format) and CSV (Comma Separated Value).
