User Reviews

User reviews consistently praise the app's depth and real-world usefulness, especially for business finance tasks and real estate work. The app offers a powerful feature set, including amortization tables, and is supported by tutorials and online help. Many see it as a strong replacement for a physical HP calculator and a reliable go-to tool. However, recurring caveats include monetization/frustrations with in-app purchases, a learning curve and usability differences from the HP experience, and occasional bugs after updates. Overall, it's a capable, feature-rich calculator that benefits from polishing.

Recent reviews

I still have my old HP 10b from college, and it's awesome. I need one to take with me all the time, so I bought this. I was hesitant, since the reviews for the actual HP 10bii+ are mostly negative. Turns out this app is great. I highly recommend it.

This is standard math, the expectation form an $7 app is to make its easy for a lay person to use and not have to use youtube videos to learn how to get an amortization schedule. I could have done that with Excel PMT. I wanted a lazy solution but this isn’t it, i wish i had not spent the money

I wanted to hit the same keystrokes on this calculator as I do on my real calculator. That doesn’t work. It keeps open up dialog boxes that have more questions than the single input I was looking to put in. I am sure if I spent time I can figure this out, but I really just mindlessly wanted to hit the same keystrokes because my calculator was not close by. I can’t believe I paid for this when I thought it was going to be the same. How do I get my money back
