Expense Register is a very simple but efficient application for keeping daily expenses.

The application is intended to be used in off-line mode. There is no integration with portal(s), web storages, etc.

Personally I am using it together with GnuCash (http://www.gnucash.org) - the greatest financial-accounting software in the universe ;)
I keep my daily expenses in Expense Register and from time to time I export them to GnuCash.
It seems to be a common use case so I believe it can be easily adapted by Quicken, MS Money, etc. users.

The major requirement for the application was to minimize the effort needed to record expenses.
I was fed up with using general purpose notes applications and complex mobile accounting software available on the Android market.
So in Expense Register I did my best to minimize number of operations needed to perform common actions.

No signup needed. No AD. No limited. No fee.
Enjoy !

Features:
* Registration of expenses

Usage Hints:
* You may use TAG field to categorize expenses. E.g. you may mark different accounts or currencies.
* You may define comma-separated lists of descriptions and tags you often use. The application will suggest them later when you start filling information about new expense.
