It's hard to know if I have pressed a function key or not, unless I either go ahead with incorrect input and hence answer, or start again. - There should be colour themes for all your BA II pro, grey one as well as the current black-red, so it's a seamless experience when I move between the app and physical calculator - Finally, if you really want to make it better, consider adding a history feature to be able to go through the last few, say 50-100, calculations ### 2/5 — Wrong calculations *2021-06-08* Wrong calculations. It doesn’t match the answers of my professor!!! Something is wrong **Developer response:** We would like to help you resolve your issue. Please contact us at 1-800-TI-CARES or ti-cares@ti.com so that we can assist you. ### 4/5 — Bond function *2021-04-06, version 1.7* Cannot calculate dates in the middle of the year. For example, I was doing a problem and I was trying to use the bond function with the SDT as 15.1.2020 and it’s giving an error ### 5/5 — Thanks for the big screen *2020-10-31* Thank you for returning the full screen to the best calculator App to me! Finally, I can see the buttons and numbers again. You listened! You care! That’s a strange thing now-a-days. And, appreciated. ### 2/5 — Please allow switching back to BA II Plus *2020-10-30, version 1.6* I am studying for my exam, for which I will use the BA plus, not the pro version. I bought this app for the identical interface to the BA Plus. Please add an option to go back to the no pro version!! ### 5/5 — New design is frustrating *2020-10-29* I don’t understand why the new design of the calculator doesn’t use 100% of the screen’s real estate? The new design has a WORTHLESS black band on either side of the calculator, forcing the buttons to be unnecessarily small. Next “improvement” should be to remove these black bands so that 100% of the iPhone’s screen real estate is used. It seems so logical, a company like Texas Instruments should be able to figure it out. Well done, sirs. Well done. ### 2/5 — Really not worth it *2020-09-08, version 1.5* Its a short of the actual calculator by a lot. Not worth the price, this should be a free download. Horrible business move Texas Instruments. ### 5/5 — Works Great!! *2020-09-03* This is just like professional version I usually use, only it’s way cheaper than buying a replacement. Would definitely recommend! ### 3/5 — Hate the update. *2020-08-26, version 1.5* I love the calculator, but hate the update. Now it is significantly smaller and leaves water space in the margins. ## Most critical reviews (10 lowest-rated) ### 1/5 — Design Looks Horrible *2023-09-03, version 1.7* Go back to the previous design that replicated the physical calculator. ### 1/5 — Inability to use the calculator *2023-01-18, version 1.7* Please I need help with this calculator, I can’t use the bracket key and the *raise to the power of*. I don’t know how this app works and I desperately need it for my finance class. ### 1/5 — Garbage *2022-03-02, version 1.7* Needs lots of work, I want my money back ### 1/5 — Got a refund *2021-03-02* Put off by the 2.5 stars, I bought this app that emulates a calculator whose base functions haven’t improved for the past 30 years. After overcoming the gall of TI’s total lack of innovation while still demanding $15 (and don’t get me started on what they charge for the physical calculators), I expected it would still at least work. But the CF function doesn’t even remember what I just put in and can’t go past CO1. Garbage company, garbage app. I’d almost rather calculate by hand. ### 1/5 — Does not compute *2021-02-20, version 1.7* This has not worked since I purchased it. Gives erroneous answers. Compared it to several others. Waste of money. ### 1/5 — Error 5? *2021-02-16, version 1.7* get error 5 for every question. ### 1/5 — Loved it before *2020-11-25* The new look makes it harder to use and has unbelievable mistakes, like the key that reads “TMV” instead of “TVM”. Please give us back the version that looks like the real calculator! ### 1/5 — Bad views size on iPhone 5s *2020-09-21, version 1.5* The last update in not fit with iphone 5s screen , since it is narrower than the phone screen. Seems only fit with the newer iPhone version only. Get me back the old calculator version ### 1/5 — ugliest layout - why was this “updated”. avoid *2020-09-14, version 1.5* total waste. avoid until they return to its old layout. ### 1/5 — Output wrong Value!! *2020-08-18* Set the BGN mode, enter N=3, I/Y=10, PMT=-200, CPT FV The result is 1997.669 which is totally wrong!! My real calculator with the same entry tells me 728.20 which is correct! Please fix it!! ## Most praised reviews (10 highest-rated) ### 5/5 — Super! *2026-03-12* Sehr guter Finanztaschenrechner! ### 5/5 — Awesome *2025-12-18* Works perfectly. So nice to have this calculator in an app. No idea where the negative reviews are coming from. ### 5/5 — Emulates the Professional version of the BA II Plus *2025-12-06* This app emulates the Professional version of the BA II Plus with two minor but helpful exceptions. I have the app and the physical version of the calculator. The app is excellent. If you need help, the help key actually takes you to TI’s online manual, which is excellent. You can’t do this (obviously) with the physical calculator. The other difference is the COPY command above the IRR key. This command copies whatever is in the app display so you can paste the information into a spreadsheet, word processor, etc. The price of the app is good considering you can use the app on your iPad, iPhone, regardless of how many devices you have. ### 5/5 — Works like the real thing *2025-10-11* Works like the actual calculator. I have been using this as my main calculator app for more than 10 years. ### 5/5 — Well made calculator *2024-02-10* 돈값 합니다 ### 5/5 — Works like it’s supposed to *2023-12-21, version 1.7* No frills, works like it’s supposed to. Used it to prep for all three levels of the CFA. ### 5/5 — Simply excellent *2022-11-08, version 1.7* It’s the TI calculator I’m used to using, in app form. Don’t have to carry a separate calculator. It’s perfect. ### 5/5 — Application deserves 5 rating *2021-10-02* I downloaded this app and it has been absolutely perfect in every way. Perhaps users don’t know how to use it which explains the low rating ### 5/5 — Great! *2020-12-15* Glad to see the professional version as an app. Win win for both sides!! Thanks TI Developers and People in charge for making the decision to make it available for professional version. ### 5/5 — Awesome!! *2020-12-11* Love this app. Functionality just the same as the calculator but I can have it on any phone. I did like the old look. But still works the the same as always! Thanks!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
