The bug happens when I do serial additions and subtractions that should result in the answer of 0. Instead I will sometimes get a very, very small non-zero result such as -1.43665 x 10 to the minus 14 power. This bug was first noticed as I was reconciling my checking account. The bug is repeatable, and is most frequently triggered when negative and positive numbers are added and subtracted as would happen during a financial reconciliation. I was hoping the August 2026 update would fix this problem. I installed the update and reconciled my checking account as I had previously. The error noted above continues to exist so I am lowering my rating because the prime utility of any calculator is accuracy. ### 3/5 — Won’t put a button on my phone *2026-07-18, version 1.7.0* Paid for the upgraded version to avoid the ads. Can’t get this Pro version to appear on my phone. Have to go to App Store every time I want to use Pro version. Very annoying ### 3/5 — What’s wrong *2026-01-18, version 1.7.0* When I try to set the P/Y to 12, the calculator returns a value of 6 (or now 1 after in reinstalled). I’ve cleared all the registers and it still malfunctions. It used to work fine. Now there is this glitch. ### 2/5 — OK - Slow Button Response *2025-12-16, version 1.7.0* I previously used a BA II Calculator app from a different developer, but had to change when my phone updated to IOS 26. Bought this Pro version and disappointed with the slow response of the buttons. Also would be nice to be able to see entered values in the N, I/Y, PV, PMT, and FV functions as other developer versions of the BA II are able to provide. Have not had any issues with incorrect calculations. Will stick with this app since I paid for it. Will update review if I see future improvements. ### 4/5 — 计算error *2025-08-25* 不能计算类似 （-5）^（1/3） ### 3/5 — More digits *2025-08-09, version 1.6.9* I wish it can process numbers in greater than 10B ### 4/5 — When doing a CPT on PV or PMT, the result is coming up negative (right value, wrong sign). *2025-08-03* When doing a CPT on PV or PMT, the result is coming up negative (right value, wrong sign). This does not occur on my physical BA-35 calculator. ### 4/5 — Excellent BAII Plus Emulator *2025-07-13, version 1.6.9* Great app, but can you please add ability to type with keyboard on the iPad version of the app? ### 3/5 — 为什么我算的会出错？ *2025-04-14* 一样的步骤会出现不一样的结果为什么?会出错搞不懂 ### 2/5 — Display forever on *2024-12-09* This app does not allow system to turn off the display, my phone kept lit for entire night because this app was on. There is no setting to disable this also ### 5/5 — Wrong manual link *2024-12-08, version 1.6.3* The Menu button at the upper right has a link to the Non-Pro manual. It should link to the Pro version manual for this BAII Plus PRO Emulator. This quick link to the manual is geared to have as a reference, but please link it to the PRO manual. ### 5/5 — Best one out there *2024-12-03, version 1.6.3* This has been a great calculator. Just like the one I used that I carried in my briefcase only now I have it with me all the time. ### 5/5 — Works great. *2024-11-15, version 1.6.3* Works great. I often forget to keep the BA2 nearby (leave at office for example) so useful to have on the phone ### 4/5 — Identifiers permission? *2024-10-04, version 1.6.3* I enjoy the app on both Android and iOS but what the identifiers permission is used for? ### 5/5 — Good financial calculator *2024-06-02, version 1.5.1* I’m an MBA student and this is exactly what I need for my finance classes. I’m also glad this is a one-time purchase (I am tired of the trend of making everything a subscription) ### 5/5 — Thanks *2024-04-18, version 1.5.1* I appreciate for this app especially when I just lost my BA II financial calculator ;) ## Most critical reviews (10 lowest-rated) ### 1/5 — Update required for IOS 26 for resize the App size on screen for using it Other APPlication *2025-10-21* Update requires for IOS 26 for resize the App size on screen for using it Other APPlication. Like while solving question on other web-page or screen, calculator app does not support for resize the windows as per IOS 26 updates on IPAD and IPhone. ### 1/5 — Time Value of Money Fails *2025-06-28, version 1.6.3* The time value of money calculations don’t work at all making this app utterly useless. It is junk! ### 1/5 — Doesn’t work on iPad *2024-11-29, version 1.6.3* Refer to the title ### 1/5 — Computes incorrect *2024-08-19, version 1.5.1* Any TVM computing is incorrect. At the beginning I tried to calculate TVM and it was fine, but when I bought Pro version every computation is incorrect. Easiest one with compounded rate shows nonsense output. ### 1/5 — Display is terrible for iPad *2024-02-19, version 1.5.1* What a joke. Waste of $ ### 1/5 — Paid for ad removal, ads were not removed *2024-01-15, version 1.5.1* I feel like I’ve been scammed. Has anyone else been ripped off like this? ### 1/5 — Cheating Fake *2021-03-05, version 1.0.8* The system is wholly wrong when performing financial calculations. Cheat! Don’t buy! ### 1/5 — Does not support landscape mode *2021-01-08, version 1.0.8* Can’t believe this does not support landscape mode!! There are better apps out there that show history and support landscape. ### 1/5 — Not intuitive *2020-02-22, version 1.0.5* Doesn't fit ipad. Not easy to use. For a financial calculator its not intuitive. ### 1/5 — Shouldn’t have bought this *2020-02-04, version 1.0.5* It doesn’t do Nominal Rate. I should have looked before I purchased it. ## Most praised reviews (10 highest-rated) ### 5/5 — Just like the real thing *2026-08-16, version 1.7.0* This calculator app works just like my physical BAII Plus calculator. It’s super convenient to have in application form for making quick calculations without having to remember to bring or carry around my physical financial calculator. Well worth the one-time payment. ### 5/5 — One of my favorite apps! *2026-08-15, version 1.7.0* I use this app almost every day. I still remember back in undergrad and grad school days when we had to lug around the actual Financial Calculator. This is so nice. ### 5/5 — Exactly what is needed without adds and extra junk *2026-08-04, version 1.7.0* This got me through my MBA! ### 5/5 — Fantastic App *2026-02-09, version 1.7.0* Reliable, works as it should. I use it all the time. ### 5/5 — Not always accurate *2026-01-30, version 1.7.0* I give this app 4.9999 stars because it is a nice implementation, but with what must be a bug that gives periodically incorrect results. The bug happens when I do serial additions and subtractions that should result in the answer of 0. Instead I will sometimes get a very, very small non-zero result such as -1.43665 x 10 to the minus 14 power. This bug was first noticed as I was reconciling my checking account. The bug is repeatable, and is most frequently triggered when negative and positive numbers are added and subtracted as would happen during a financial reconciliation. ### 5/5 — Solid calculator *2025-10-13, version 1.7.0* The BA II Plus Professional performs well. It’s fast, accurate, and handles complex financial functions. It takes some time to get familiar with the layout. ### 5/5 — Great app *2025-10-12* Although vibration doesnt seem to work ### 5/5 — When doing a CPT on PV or PMT, the result is coming up negative (right value, wrong sign). *2025-08-18, version 1.6.9* When doing a CPT on PV or PMT, the result is coming up negative (right value, wrong sign). This does not occur on my physical BA-35 calculator. *** After communicating with the developer, they explained what was occurring. I have updated the review to 5 stars *** ### 5/5 — Superb Business Calculator *2025-08-17* Super app. Works like magic. ### 5/5 — Better than the actual calculator *2025-03-19, version 1.6.3* I stopped using my BAII Plus because this app is better, easier to see, etc. Awesome and totally worth the money!!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
