10bii Financial Calculator Customer Insights

1. Thanks Kenny!This is a great financial app - there has been an issue with Google play the past couple of days that has been resolved - don't let this discourage you from using this app - I have been using this for years and once you get used to using it you won't be able to live without it - also, Kenny was a great help and very responsive during the issues with Google playWorks just as it should and everything is arranged exactly as on the physical calculator.

2. Bought the app and paid extra to unlock all functions btw, but still way cheaper than ordering a standalone calculator.I remember I did some pretty good research on finding the best financial calculator app when I bought it for my MBA classes 5 years ago.

3. I have been using it frequently ever since including in my personal life and it works incredibly well and is feature packed!I'm a real estate investor and money lendor.

4. Android 12 is temperamental so to have a developer stick behind you is awesome! This calculator is second to none & the only one I use for simple math to major problems.

5. They are close but not correct.UPDATE: It's finally fixed and it's due to the help of the developer Kenny who not only took the time to contact me & help but followed up twice to give suggestions & help.

6. Thanks.Super solid calc, that actually shows all TVM values at the same time! If I'm nitpicking, I'd say the orange and blue alt-function fonts could be a bit larger _before_ toggling them on (LG G6).

7. I like the 10bii+ because the clicking sounds when you touched the keys are just right (the clicking sounds of the competitor calculators are a bit too soft, using a different tone, or no sound).

8. I like how it is so far but at the same time you should tell people that they will have to make an additional purchase of $3.99 within the app to unlock the rest of the features (basically the rest of the blue buttons).

9. This calculator is truly a 10bii + after you make the second purchase but it is actually a HP 10B when you first get it.Up until recently, I loved this app.

10. Still, nice work!!Probably one of the most handy tools to run a quick analysis from my phone reverse engineering a mortgage if I am missing a piece of data.

11. This seems to have changed sometime over the past couple of years (not sure when).
