    I have used this calculator for months (perhaps years) and it has always provided what I want.

    Don't need everything it has, who does? But it has those one or two things I need and does them very well.

    No otther calculator app compares, it has so many features and is just as smooth and sexy as others. Its like having several high level calculator forms and the standard ones all in one. Not difficult to use even has a guide.

    Offers about everything you need to munch numbers. Especially the dec hex oct bin conversion is my favorite!

    APP was fine until last update. What a mess. It force closes--stops. Fix asap! Update. Thankyou for responding so quickly. My favorite calc is back to operating.

    It was definitely worth throwing a few nuts to feed the little furry thing and help keep it growing. Excellent work devs!
