Looks Like An Hp 10b II, But Works Like A 30b
Ernest Brock makes the best calculators for the iPhone and iPad. Period. They are all feature rich, attractive and they just plain work. So many apps are plagued with bugs and you have to wait for updates only to find the update messed something else up. Not so with his apps. They are all well thought out and excellently designed. The 10bII HD is a perfect example. He started with making a great looking Hp 10bII calculator, but added features the calculator was missing. Even though the calculator would handle TVM and Statistical functions the programmer added in worksheets with tables that makes using those functions so easy. The worksheets alone make the app worth buying. A number of other handy worksheets are also included from leasing decisions to Black Scholes bond valuations. This app has more features than the top of the line Hp 30b and 17bii+ calculators, but with the built in tables it is much easier to use. There is also a built in users guide. And customer support is outstanding. This app would be a bargain at twice this price. But at $5.99 its a steal.
