"It will NOT do the calculations correctly! I do the problem on my real calculator and then side by side with this app, and the app is wrong."
"I bought this app to use in place of my hp 10BII I need to use for an exam - I left the regular one at home thousands of miles away and couldn't find a replacement abroad - but it is not similar to the regular hp."
Users are frustrated by charging for updates and add-ons after paying $7-10 for the base app. Multiple complaints about in-app purchases not working properly and charging $0.99 for minor updates. However, no complaints about the initial price point itself.
Users demonstrate high willingness to pay ($7-10 base price, plus willingness to buy upgrades for specific functions like bond calculations) when they believe the app will work correctly. They compare favorably to physical calculators and TI BA II Plus alternatives.
