### 5/5 — Just like the real thing

*2026-08-16*

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*

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.

### 3/5 — Won’t put a button on my phone

*2026-07-18*

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

### 5/5 — Fantastic App

*2026-02-09*

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.

### 3/5 — What’s wrong

*2026-01-18*

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*

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.

### 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.

### 5/5 — Solid calculator

*2025-10-13*

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
