This scientific calculator has been created to overcome the lack of a both good and nice looking calculator on App Store. I spent my high school and university periods using hardware calculators, they were very quick to use, but I always thought why should I carry around a second device while I have my phone in the pocket. So I searched for years for a good calculator app that was able to replace the hardware one, but I never found one, they were all too unhandy to use, with important buttons on a second page, annoying to reach when you need them often; with a complex interface and very difficult to tap and edit directly on the calculation. I thought it's crazy that no one have exploited the amazing system provided by Apple to not only create a really good scientific calculator, but to make it even easier to use and interact with than the hardware ones. So I decided to do it. What CalcMe offers: - Nice looking interface, intuitive, immediate and able to not only replace, but to enrich hardware calculators. - Elegant and modern themes and colors to choose from, all included in the first purchase. - A little magic feature: in scientific notation, swipe over the result to move the decimal dot and see the ten power change :) - All scientific function (sin, cos, tan, ..., log, ln, exp, ..., atan2). - Calculation structured in 2D, with fractions, powers, roots, brackets and so on, with very easy to nest operations, no limits! - Tap on the calculation to place the cursor and write. - Undo/Redo buttons - A catalog with 40 physics fundamentals constants, with name and unit of measure, ready to be inserted. - Possibility to store values. - Chronology. - Sliders: yes, you can insert many parameters and change them swiping on a slider to see the effect in real time. - Spaces: access to up to 4 spaces on which you can edit and keep calculations, useful also to superpose different plots. - Joystick mode: swipe over the buttons to move the cursor (still in beta). - Plots: inserting a variable, like x or y, the calculator automatically generates the plot. - Locus of points: if you insert both a variable and the = symbol, instead of showing the function of the variable, it is shown the locus of points. - Complex numbers: the app automatically uses complex numbers when needed, no need to set the complex mode. - Plots also support for complex values. - Integrals and derivatives (in the future also limits). - Export plot and calculation as image/PDF, copy result as text Enjoy! I wish this app existed while I was a student.
