Ratings and reviews

Really nice so far. Would like to see some theme options (black and blue or at least dark). Actually the screen shot theme looks great. When installed it's grey, white , and orange. Maybe I'm missing the theme setting?More conversation options perhaps. Binary, hex, oct calculator. But really it is already very nice and easy to use, with nice options.

Great, simple, practical, easy-to-use calculator that suits all needs. Keeps track of numbers so a mistakenly entered one can be deleted and the correct one can be entered without having to start the calculation over. Can be used to convert units and currency and calculate discounts, tips, loans, and even dates. Big, easy-to-read display. Basic and scientific calculator options. All around, superb! Best calculator app I've ever seen or used. Would donate to creator if I could do so via PayPal.

Nice interface. Lots of useful applets. A couple of things I'd like to see... 1) A memory feature to make it easy to do repetitive operations with an intermediate value. 2) The ability to enter US distance such as inches, feet and miles as fractions (eg 3/16 inches). Thanks for sharing your work!
