Best Calculator Ever – i41CX Review

Not only was the HP41 the best calculator ever, this app is the perfect reproduction of it. The thing that really impresses me is that the app creator continually maintains it for new iOS releases, fixes any (rarely found) bugs and adds features. I've used this app since I bought my iPhone 3G and have never had a problem. Highly recommended!
