Description
Graphing calculator with algebra. Essential tool for school and college. Replaces bulky and expensive handheld graphing calculators.Multiple functions on a graph, polar graphs, graphing of implicit functions, values and slopes, roots, extremes, intersections. Algebra: polynomials, polynomial equation solving, matrices, fractions, derivatives, complex numbers and more. Shows results as you type. Use menu to switch between modes.
Free version requires internet connection and contains ads! $5 in-app upgrade to PRO. Contact us if you need multiple licenses for a school or organization.

Best I've come across I have a hobby of going through the app store and trying out calculators. This is the best I've come across that has a lot of functionality with a good user experience.

Greatest app on my phone! The graphing capabilities are great! I wish it was able to do some graphs in the xyz plane but it's still a great app! Polar graphs and matrices??? Now that's awesome!
