Produces incorrect result
Kept giving incorrect answer
Worthless
This is horrible... does not work when I want to use for conversion.
Simply excellent rendition of classic
The 10bii is the financial calculator for people to compare financial opportunities and products. This app is an excellent version of my trusty physical 10bii. The calculations are accurate. Great additional features in the worksheets.
The best 10bii ever
I have been using it for years, it works great. The calculation is fast and the UI is clean and easy to use. The developer listens to you when you have any suggestions. Thanks for great app.
When trying to calculate standard deviation
Sigma button doesn’t work!

Incorrect calculations
This calculator produces incorrect results beware! A simple Rate calculation, with PV -1757, N 19, PMT 0, FV 8,254 produced a I/YR of 101.8! The correct answer is 8.7. If you are doing several calculations and rely in this calculator you might be embarrassed when presenting your results so don't trust this app!

New user
I’m a new user, but became facile in minutes. Great app!
The free apps are better
A bad purchase, I was so frustrated with it I ended up using a free app. Apple should have a money back guarantee on paid apps.
숫자가 대충 10~12개 넘어가면 앱에서 튕김
이럴줄알았으면 계산기 살껄
Keeps crashing
Was working great for a while but now keeps crashing when doing certain calculations like amortization
App is back
After it crashed and burned on iOS 13.1, latest update has fixed the problem. Very clean financial calculator emulator.
アップデート万歳！
先週（2020.2末）ようやくiOS13で起動するようになったようです。
ちょっと対応に時間かかり過ぎでしたがとりあえず使えるようになってよかったです。

Works again
Hooray!
Doesn’t work with iPhone IOS 13 !!!
The app was great until my iPhone X was upgraded to IOS 13. Now it won’t load!! I’ve sent multiple emails to support, but it’s like a black hole!! No response whatsoever.
I saw your response today, Feb 26th, and tried the app. Yes, the app now works on my iPhone X. Unfortunately, I needed the functionality for the last 3 months and had to purchase a 10bii app from a competitor. I was NOT HAPPY. You should have fixed the problem in a timely manner. 3 months is NOT timely.

Doesn’t load after recent Apple software updates
I’ve been using this app for several years and have been very pleased with how it performs and how it closely mimics the HP 10b calculator. However, after several recent iPhone software updates, the app is non-responsive and the phone must be powered off and on before the app will open. Please fix !
Feb 26, 2020 Updated Review: Thank you for updating the app and correcting the problem. The app works great !

Thanks for getting it fixed
Finally an update and now the app seems to work. I had found another app that I like better overall but this one makes some functions like TMV easier, so I will give this app a try again.
Thanks for getting an update out.

Doesn’t work iOS 13
The calculator worked as expected until iOS 13 was released. Now the app immediately crashes on my iPhone and my iPad.
Update - the developer fixed the bug and the calculator works again. I raised my review up to 4 stars rather than 5. Unfortunately for me I already bought a different 10bii+ app.
