reviews and complaints

I purchased a. I pad version of the calculator. I have used it for several years. In addition I have two of the physical TI ba 11 plus. The latest update 12-2019, I am unable to change settings in the 2nd level. Specifically changing payments per year to 12. The default is one payment per year. The instructions are the same for my hand held and for the I pad version. The hand held works fine. I can adjust to 12 payment, or 4 payments. The latest version DOES NOT WORK for the iPad. Very disappointed.

Clearing multiple times still doesn’t reset the functions properly. Calculating known equations consistently brings up incorrect calculations. You have to go through the entire reset function every equation to ensure you get the correct answer. The reliability of this is extremely poor. For the price, you are better off getting a real calculator or downloading a different app for the assurance that you will actually get the correct calculations. Very disappointed

As a financial professional, this app had the same look and feel of the actual BAII calculator, which was very useful on a day to day basis. I updated today, and I get this garbage layout with tiny buttons that you can’t hit, and the entire screen is MUCH smaller than the other. I paid for this app 8 years ago, paid $14.00 the full version, and have used it on a daily basis. This is an absolute slap in the face to everyone who paid for this app. TI needs to fire the person who greenlit this. Go spend your money elsewhere.

I purchased this app for a college class that I'm taking. I was excited when I found the app and I didn't needs to purchase the calculator, as I didn't need another item to lug around. It worked great when I installed it; however, since the multiple IOS updates it is not functioning properly. The keys are very small and the readout screen is very hard to read. I haven't had any troubles on my iPhone, but this is getting ridiculous! I would gladly give this app a 5 star rating when it is returned to its original means of functioning, until then it gets 1 star. Get on the ball, Texas Instruments!

This is a great calculator app from TI that says exactly what it does: it represents the TI BA II Plus which is used within the business and finance field everyday. As a CFA candidate this is an invaluable tool when it isn't feasible to carry your own stand alone calculator and you want to run through some practice problems. It's also a great tool for Mortgage Banker/Loan Officers who prefer TI's design over HP's products. The app works well and fast. It is accurate and was tested through problems from CFA course work with both this app and the real life counterpart. It starts quickly. And that's pretty much it. Enjoy.

This iPad version of the TI BA II Plus is just as good and accurate as the handheld version. I read all of the posted reviews, but couldn't believe that the ap had the problems and glitches described. I suspected that the reviewers just didn't know how to work the sophisticated tool. All of the features about which previous reviewers complained are simply the result of not knowing how to use the calculator. Amortization works fine, payments are computed correctly when the proper number of payments per year is entered. I suggest that the operating manual be made available to those who can't work this valuable tool.

I am very happy to have this ap on my iPad.

I've used TI real-world calculators for many years and like them. Sorry to say, this program has problems and I do not recommend it.

1. Slow: It is slow and sluggish. Example: Enter 10 digits just a little too quickly and it will often miss two of them!

2. Precision: It is limited to just 10 digits of precision and a decimal exponent of 99. This was cool circa 1985.

3. Value: As iPhone apps go, this is an expensive one and its defects make it a poor value.

Tip 1: For those of you looking for documentation on this calculator, get the PDF for the real-world TI calculator from the TI website.

Tip 2: I kept looking and found PCALC which is everything this TI calculator is not: Fast, responsive, high precision (15 digits), decimal exponents to 260, unit conversions, keypad layouts, highly customizable and polished.

I don't need precision to 9 decimals because I'm not sending man to the moon using my iPhone. I don't mind the couple seconds that the screen takes to load because my job doesn't require me to load and close this app constantly all day long. It is expensive for an iPhone app, but way less so than buying the actual calculator. That is a great value; after all we aren't buying Angry Birds here! It is a financial calculator! As such it simply and easily illustrates financial scenarios. Those change constantly in real life, so as long as its close enough I don't understand all the crazy reviews freaking out about the values being off by a ten-thousandth or whatever. If you are going to write a contract with legally binding numbers go get the real calculator, or buy industrial strength software and stop crying about this really fine looking (pixelation and blurry - seriously?) and fine working application that is way easier to have at a meeting away from the office than the big real calculator!

This app works just like my real ti baii plus calculator, and i have used it frequently when i don't have my standalone on hand at the ready. However, this app has one bug and it's a major drawback for me.

I am a mortgage loan officer and I have the need to use a financial calculator on-the-fly. I'm using the app on an iPhone 4S with the latest iOS update as of Jan 2, 2012. Frequently I need to use this calculator during an iPhone cellular phone call. And this is when the bug occurs.

For example, a call comes in on my iPhone and I need to use the calculator. I hit the home button then launch this app. The far left side of the screen which makes up the left column of buttons on the calculator is blank (black). No graphics are rendered.

If you already own this app, call 611, then try to open the app while on the phone. This bug occurs. To restore the calculator, one has to subsequently shut down the app, disconnect the call, and the relaunch the app.

FYI, pressing the home button won't completely shut down the app. U need to double click the home button, find the app in the bottom row, press and hold down the app until the minus sign appears, then press the minus sign. Otherwise when u relaunch the app, the left column of the screen from the calculator will still be missing.

Once this bug is corrected my rating would be 5 stars. I hope this is corrected soon.

For those that were critical because the "out of the box" interest setting payment was 1 payment per year, just change this setting to 12 payments per year. The calculator app will stay this way unless you change it in the future. Loan calculations will compute perfectly.

I am like so many users who loved the look of the app when it looked just like the Business Analyst and the UI was perfect - it has now been ruined with an amateurish UI that takes away its unique look among Apple calculators. Bring back the old UI PLEASE!

Why did you change a perfectly fine app that actually resembled the calculator into some low qualify sci fi phablet looking device? This app was not broken, and somehow you made it worse. The best perk of the app was that it looked like the physical calculator.

I agree with others that paid for the app that replicates the actual TI BAII Plus. I paid for an app knowing what I was getting, and I now feel I have been cheated from my money. This new user interface is terrible. Please, bring back the old app, or give the app user the ability to use the old version. I have to question who at Texas Instruments thought this new app looked good.

The update is not good.
The keys are microscopic.
It doesn’t look or feel correct.
Why pay for a BA II Plus app if it’s just another lame calculator app?

We originally paid for a BA II plus EMULATOR.
And it WAS but now it isn’t.

Guys... lame.

Seriously where are the updates. The application does work. But it has some lag to it. The normal calc runs so much faster. Common TI you guys need to push some updates here. Your stock is doing decent so please push out updates and be regular on it. Thanks

I loved this app for years because it is like having my normal BA2 plus in my pocket at all times. Out of nowhere they change the look and add useless black bars to the sides. I started using the free Apple calculator. Don’t buy it until they change it back.

I just purchased this product and to learn the use of the app I've followed the example provided under the help key. When I enter the information shown, and them press the "cpt" (compute) key + "pmt" key to calculate payment I get -5,052.39... Which is WAY OFF!

This app opens full screen on an iPad with no way to be used split screen with other apps. For a calculator app, that is ridiculous.

Also, the majority of people who are purchasing this app are professional users since clearly students wouldn’t be able to use it on exams anyway. So TI, please give us the professional functions!

Dudes! What in the world are you thinking? The whole point of this app is to emulate the old calculator that we all loved. By making it look like any other calc, I might as well use the built in Apple calc. So disappointing. If I could have written the review with NO stars I would have done it. Way to screw-up a great app. “Thanks a pant-load!”

Overall very good but very disappointed that the calculator only works in portrait mode (like an i-phone-only app). So when I have it on my keyboard, the calculator is on its side!

Would give it 5 stars if it had landscape display. As it stands, they should be selling this as an i-phone app only. I suggest you get the 10bii Financial Calculator, it displays landscape!

This has not worked since I purchased it. Gives erroneous answers. Compared it to several others. Waste of money.

The app is not able to correctly calculate annuities, which is obviously a serious problem. Do NOT buy this calculator until this error has been corrected.
