Salary Recorder
An app for recording the information on the pay slip you receive each month. You can aggregate and chart the recorded data by pay-slip item to track how your salary changes over time. Four income and four deduction items are provided by default, and via in-app purchase you can increase them to up to 20 items; you can also record your work status (days worked, overtime hours, and so on).
There are many kinds of household-budget apps on the App Store, but I couldn't find one specialized in recording pay slips, so I developed this app. It is useful when filing my tax return.
