Is there an open source #Android app (preferably via #fdroid) which allows you to track how much money you spend? Something like #HomeBank or #gnuCash but for the mobile phone?
The features I'd like to have: Multiple accounts (e.g., bank, cash, savings), categories for each transaction, recurring transactions (e.g. for rent)

Thus, the BasicCashFlow app from the fdroid store is not sufficient for me.
