MathStudio Express, a full-featured scientific calculator with hundreds of mathematical functions that cover Basic Math, Pre-Algebra, Algebra, Trigonometry, Precalculus, Calculus, Statistics, Finite Math, Linear Algebra and Statistics. "MathStudio is a natural for students and for engineers who occasionally need a comprehensive math program but don't need the full horsepower and daunting complexity of Mathematica or Maple. It's a huge leap from the usual calculator program for tablets and smartphones." ▸ IEEE Spectrum Review by Kenneth R. Foster MathStudio is an indispensable tool for students, teachers, and engineers. It provides features comparable to TI calculators but with a modern and intuitive interface. "I've been waiting for a program like this a long time on my iPhone or iPad, and somehow never found MathStudio until now. This is a phenomenal engineering application for the student or professional. It does it all... Solving equations, integrating, calculating derivatives, and graphing. I had a TI-92 calculator back in my college days that I used for years and dearly loved and this app blows it out of the water. The UI is extremely functional and intuitive to use. They include a really quick tutorial that gets you up and running quickly. This is the example app for the potential of a device like the iPhone or iPad. Superb!" ▸ Fantastic... It's a TI-92 on steroids by Dan Frame Graph equations with speed and ease you never thought were possible! Move, rotate and pinch function, parametric, polar, implicit, contour, spherical, cylindrical, vector fields, fractals and image plots with amazing speed and accuracy. Use the T variable to create animated plots that graph in space and time! MathStudio is the first calculator to introduce time graphing when it was first released as SpaceTime in 2003 for Pocket PC. "This is truly an amazing piece of software for the iPhone that could potentially render all the graphing calculators out-there obsolete! I was very impressed with all the graphing features (2D, 3D, 4D, etc) and the powerful CAS loaded with preprogrammed functions. MathStudio solves and displays complex expressions in a fashion that reminds me of my TI 92's 'pretty print' mode. I highly recommend this application to every college student and math enthusiast!" ▸ Dump your graphing calculator! by Syldaril Plot lists of numerical data in scatter, histograms, box, and probability plots. MathStudio even includes an advanced regression analysis package, choose from several regression functions or create your own. "I am so lucky to find this application! I will never use TI-89 again! And the price is unbelievable! And you can do scripts! TI-89 costs over 100 dollars. You can use this application instead! Too bad our professor doesn't let us use phones on the test. I will try to convince him by showing this application. MathStudio is well worth the money." ▸ Wow! by aurorae_borealis MathStudio is powered by that fastest proprietary computer algebra system available on iOS that beautifully typesets your answers. Got a tough algebra equation to solve or polynomial to factor? Solve quadratic equations, systems of equations, limits, derivates, integrals, differential equations and much more. Create scripts in MathStudio's powerful programming language that supports variables, loops, and recursion. "This application is simply amazing. I continue to be stunned by the speed and accuracy in which it solves/plots/does just about anything you could possibly need to do in math. I prefer it to computer math applications because you simply cannot beat the touch interface. This app has changed the way that I do math every day, and I highly recommend it to anyone who does math on a daily basis." ▸ Amazing by rationalresponse

~~~~~~~~~ Check out our FREE app Console, which is powered by SIMO's MATLAB interpreter. If you find Console useful, SIMO is definitely suitable for you. ~~~~~~~~~ SIMO is a feature-rich development environment for MATLAB. We have developed a version of MATLAB interpreter that works for commonly used language syntax and functions for beginners. [+] Who will find SIMO useful? - Students learning the basics of MATLAB. - Course instructors of fundamental MATLAB courses. - Individuals whose works do not depend on specialised toolboxes and advanced language syntax. [+] What is SIMO? - It is an integrated environment for running MATLAB. - It allows you to create, edit, and run MATLAB code on iOS devices. - Unlike other apps that compute on the cloud, it performs computation entirely locally on device. No internet connection is needed. You don't miss a single app feature even if you are offline. [+] What SIMO cannot do? - It does not completely replace MATLAB, as it has only a subset of built-in functions of MATLAB. - It does not support advanced features such as Simulink or creating user-interface. [+] One app, all platforms - You will be amazed at how much work you can do on a phone. The app is designed to let you work effectively on smaller screens. - The iPad app features a split-screen layout. You can enjoy a full-screen workspace, or work on two views simultaneously. - The iPad app runs on Macs with Apple silicon as well. Buy one app and it works on all of the platforms. [+] MATLAB interpreter - The interpreter works for language syntax that is essential to survive a MATLAB course. It provides the most commonly used built-in functions for learners. - The interpreter computes on your device locally. You will not miss a single app feature even if you go completely offline. - SIMO comes with a full set of documentation and user guides. It is offline accessible and full-text searchable. [+] Visualization tool - Plots are rendered in real-time using your device's computing power. Operations such as updating line attributes, pan and zoom are fast and responsive. - Stunning 3D plots are rendered by the device's GPU in real-time. Pan, zoom or rotate with multi-touch gestures, trackpad or keyboard shortcuts. - Plot attributes are editable through the built-in user-interface. You can improvise with different styles without entering a single line of code. [+] Command console - You can run one or many lines of code from the command console. It supports line numbering, auto-intent and syntax highlighting. - Search over thousand lines of output data instantly. You'll never get overwhelmed by the sea of numbers. - Output data are formatted automatically to fit the screen size or app window. Data are always neatly presented however you resize the app. [+] File manager - Files can be synced across all of your iCloud Drive enabled devices (iPhone, iPad, Mac).
