GnuCash

GnuCash Android is a companion expense-tracker application for GnuCash (desktop) designed for Android. It allows you to record transactions on-the-go and later import the data into GnuCash for the desktop.

Features include:

An easy-to-use interface.

Chart of Accounts: A master account can have a hierarchy of detail accounts underneath it. This allows similar account types (e.g. Cash, Bank, Stock) to be grouped into one master account (e.g. Assets).

Split Transactions: A single transaction can be split into several pieces to record taxes, fees, and other compound entries.

Double Entry: Every transaction must debit one account and credit another by an equal amount. This ensures that the "books balance": that the difference between income and outflow exactly equals the sum of all assets, be they bank, cash, stock or other.

Income/Expense Account Types (Categories): These serve not only to categorize your cash flow, but when used properly with the double-entry feature, these can provide an accurate Profit&Loss statement.

Scheduled Transactions: GnuCash has the ability to automatically create and enter transactions.

Export to GnuCash XML, QIF or OFX. Also, scheduled exports to 3rd-party sync services like DropBox and Google Drive

Reports: View summary of transactions (income and expenses) as pie/bar/line charts
