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. ## Key features - Full HP 10bII+ functionality - Interactive prompts and recipes - Register views for stored values - Basic calculator functions included - Advanced financial worksheets via IAP - Customizable recipe recording ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | 10bII+: Full Functionality | $5.99 | one-time | ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/10bii-plus/id6444637585/reviews.md ### 1/5 — wrong calculations! *2025-11-18* calculations for FV, PV etc are wrong ### 1/5 — Does Not Work *2025-08-26* 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. ### 1/5 — Do not buy, cannot do TVM correctly *2024-08-16* This app cannot accurately solve time value of money entries. It throws answers that are wildly incorrect, verified against known keystrokes for TVM equations. ### 5/5 — Great Financial Calculator! Highly recommend *2024-06-20* 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! ### 1/5 — Not free *2023-09-14* Requires in app purchases for basic functions ### 1/5 — -100 stars *2023-09-10* Puts the main features of a financial calculator behind a paywall. Might as well download a scientific calculator at this point ### 1/5 — Inaccurate *2023-08-08* Waste or money, NPV an internal rate of return formulas are inaccurate, time value of money also completely useless and innacurate ### 2/5 — Error message regularly *2023-05-09* Continues to throw an error message just about every time you use it. Sometimes it freezes the phone. Very glitchy, but I wish it would work properly because it’s a great concept and easier than carrying the physical calculator. ### 2/5 — Errors *2023-05-02* IRR error when using the CFj key and I putting 0 for multiple cash flow. My hp10bii+ does not give me this error using the same keystrokes. Also, this app freezes my iPhone entirely to the point that I have to do a hard reset. Typically happens one per day. ### 2/5 — Kinda works but constantly crashes *2023-03-31* Don’t bother ## Frequently asked questions about 10bII+ ### What financial functions does 10bII+ offer?
