What’s the big deal?

Sure, I gave it 5 stars. But that’s because the app does what it’s supposed to do. It’s a calculator. I don’t understand what all the hype is about. Lotus 123 was doing this back in the 1990’s. Texas Instruments was doing this in the 1970’s. Hell, the abacus dates back eons. Sure, this app has more features, but let’s be serious, it’s a calculator for the iPad - not a contribution to the welfare of mankind!

Currency UI has issues...

#1 currency symbol should be left-aligned, next to the flag (currently throws off right justification for currencies without symbols such as HUF)
#2 app should open with my same numbers as when closed (currently resets to zeroes)
#3 if decimals are set to '2', currencies should always show 2 decimals (currently shows 2.30 as 2.3)
#4 units should be searchable (there's too many currencies to scroll through)
#5 the calculator and convertor should be either integrated, or on the same page. I'd like to add/ subtract/multiply ON the currency converter page

Simple and Functional

If you want a calculator for your iPad/iPhone that is quite functional yet easy to see and easy to use, thus is the one. It just plain does the job!
In the last update they made the numbers light grey in color on a slightly darker grey background. It was infinitely easier to see when the numbers were black. I have no idea which “genius” decided virtually no contrast was better but obviously he/she is young and has excellent eyesight, many of us enjoy neither trait.
