Highly Recommended, I Use this all the time!

I purchased this when if first came out and have found it to be one of the most useful apps available. I use it all the time and it has since completely replaced my HP 12c. The large buttons work great and the functionality is superb. I havent spent a huge amount of time on the extra features but have found them useful when I needed them. If youre thinking about a 12c for your iPhone, this is the one to get, hands down.
