An Android Calculator app that does all

This is an Android Application created by TruTech Innovations Inc.

At TruTech Innovations, we believe that our phones, with superior processing power, should take over the antiquated technology of expensive and inconvenient scientific and graphing calculators. With these ideals, we decided to create Calculall, an Android Application that brings all of the features of a Graphing Calculator, and more, onto your phone. We spent over a year developing and refining to make this calculator to be the most beautiful, effective and efficient tool to use for assisting in any mathematical problems, from finding the most complex indefinite integral, to simple everyday calculations. Calculall provides a vast arsenal of mathematical capabilities, far beyond virtually any calculator would have, while providing an intuitive, simple, and beautiful user interface. There are five modes in Calculall:

• Basic mathematical operations

• Standard functions found on most scientific calculators (such as trigonometric functions)
• Displaying fractions and superscripts naturally
• Ability to calculate in exact values (fractions) or in decimals

• Root finding for polynomials
• Factoring
• Expanding
• Differentiation
• Indefinite Integration

• Vector addition and subtraction
• Dot and Cross product
• Angles between vectors
• Unit vectors
• Magnitudes of vectors
• Scalar forms of 2D and 3D vectors

• Basic matrix operations
• Row Reduction
• Inverses
• Eigenvalues and Eigenvectors
• Diagonalization, QR, and SVD Decomposition

• Calculation History
• Custom Themes
