Fantastic and Fast
Just like my HP-12C, but faster. It makes my old calculator seem so slow in comparison. I love the two line display, the always available financial registers and the quick results. If you are an old HP-12C user, you will love this app. You could buy a free version, but why? You get what you pay for, and this is definitely worth it.
