The 10bII+ is a complete reimplementation of the full functionality of the popular HP 10bII+ financial calculator. In addition to providing 10bII+'s look & feel and functionality, we have modernized the app with features such as recipes, interactive prompts, and register views. This free version provides basic calculator functions, Math, Trigonometry, Memory, Interest Conversion, and Date functions. A one-time In-App-Purchase is required to access the Time-Value-of-Money (TVM), Amortization, Cash Flow, Bond, Depreciation, Statistics, Profit Margin, and Breakeven worksheets. The 10bII+ modern addresses two critical issues for the user: (i) knowing what is stored in each of the calculator's internal registers, (ii) remembering the exact key sequences for getting specific calculations done. The register views, accessible in the main screen, provides visibility into various register groups. You can switch between different groups of registers (such as Financial, Cash Flow, Bond, etc.), and inspect stored values. The recipes which you can record and store remove the burden of remembering the exact keystroke sequence for your tasks. You simply select a pre-recorded recipe (builtin or your own) and run. When running a recipe, the app visually prompts you with the keystrokes to press and guides you along in getting the results. The app comes with 25 built-in recipes and allows you to add/record/edit/delete your own recipes. The convenient register view on the screen allows you to view register contents as your operations proceed.
