does everything: scientific, financial. I have used it for years, no plan to switch.
works just like the one I used in college.
Fantastic help function. Free version is fully functional! Throw the developer a few bones if you use it 😀
Everybody knows how badly H-P had cut corners on the physical builds of all their calculators. This digital version of it will keep this best ever biz/fin calculator a forever legend. You guys did a super job in making this happen!!!
It is very impressive. A professional appearance
This is the calculator I have been looking for ages. It is top, top!

wonderful
Great app, but support is non-existant. Trying to buy paid version, but transaction is denied (at least 20 times). Contacted Google support, they said I should contact the developers to solve, charging for every other app is working. Forwarded the email to the developers, but they just ignored. I will still keep the free version with my other 9 calculator apps. I won't try to buy from this developer anymore.

This is the best financial calculator, so I purchased the pro version. Now after multiple years of use the app is asking for me to 'buy' the app again.

“And to top it off the free version is 100% functional with only a start up splash reminding you you can contribute to the continued development of the app.”
“I have had an actual HP 10b for decades and I love it.”
“I think a lot of people have faced the same issue.”
“The tactile feedback and sound makes for an even better experience.”
