Ttrufle Financial Calculator

About

The app interface is available only in English and Korean. Ttrufle Finance by Gorae Labs brings everyday arithmetic and financial calculations into one workspace. Calculate the time value of money (TVM), work with present and future values, interest rates, payment amounts and periods, and explore cash flows with net present value (NPV) and internal rate of return (IRR). Use dedicated worksheets for bonds, loan amortization, depreciation and statistics. Review the values you enter, move between related fields, and return to the calculator to continue your work. Guided practice helps you learn key sequences and work through financial problems step by step. Keep calculation history on your device, reopen saved work and export results as text or CSV. Your calculations work offline, without an account, ads or a subscription. Choose the display and number formats that suit your work, and switch between English and Korean in the app settings.
