Fantastic App
Reliable, works as it should. I use it all the time.
Not always accurate
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.

Whatβs wrong
When I try to set the P/Y to 12, the calculator returns a value of 6 (or now 1 after in reinstalled). Iβve cleared all the registers and it still malfunctions. It used to work fine. Now there is this glitch.
OK - Slow Button Response
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.
