HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (0.3 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

wrong calculations!

Does Not Work

Purchased to use on my MacBook to calculate IRR/NPV problems. Half the time when trying to calculate IRR, it gives me an error. Putting the same keystrokes in on an actual calculator gives me the right answer. App does not work half the time, and would not recommend.

★★★★★Aug 16, 2024
Do not buy, cannot do TVM correctly

This app cannot accurately solve time value of money entries. It throws answers that are wildly incorrect, verified against known keystrokes for TVM equations.

★★★★★Jun 20, 2024
Great Financial Calculator! Highly recommend

I use this constantly and find it so helpful to not have to carry around my physical 10BII+. Seriously, this is a very cost effective solution for regular users. I’m very happy to pay a 1 time fee of around $5 or $6 especially compared to the subscription models. If I want just a “regular, free” calculator I use the one built in to my phone. Great product developers! 👏Please keep it up!

★★★★★Sep 14, 2023
Not free

Requires in app purchases for basic functions

-100 stars

Puts the main features of a financial calculator behind a paywall. Might as well download a scientific calculator at this point

Store description

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.
