With the password, no one else but you can access the app and see your daily expense details. You can change the password later in the help menu.
This app provides you the ability to create not only new accounts (such as Cash, Bank, etc...) but also categories for your expense. The accounts can transfer money to each others (just like you deposit your cash to your bank).
Searching is very easy, just enter what you need to search or all the conditions you need to search, and the results will be there for you. Check it for yourself.
A pie chart is added in order to give you the most visually result of what you've been doing. Taping on the pie will show you your income or expense.
You can backup and import the database just in case you change your device.
If you need any help, please check the Help menu for more information.
