Free Graphing Calculator and Other School Android and iPad Apps

Updated on August 3, 2014

Download a Free Graphing Calculator

Almost everyone from Middle School through vocational school and the university needs a graphing calculator in this era.

These devices are useful, but can be very expensive. Luckily, free Android and iPhone/iPad apps allow students to download a free graphing calculator.

Graph-89 is a free app for this calculator.

Where to Find the Apps


Graphing Calculator by Mathlab (at the store, free)

  • This app requires 1.9M and Android 2.1 and up.
  • The calculator is also a Scientific, Fraction, Algebra, and Matrix calculator with a library to which the user may add expressions and other materials.
  • Dozens of capabilities are included, like my favorite: Polar Graphs

Other free downloadable calculators as apps are available from the same location at Google including the following selections:

  • Integral Calculator for calculus
  • 3-D Functions Plotting Calculator
  • Handyman's Calculator
  • Graph 89 - Emulator for the TI-89 of Texas Instruments

The first calculator available in the USA to the public was the Bowman Brain at the cost of $200 in 1971 in my Midwest city. That's $1135.14 in 2013 dollars. Bowmar was bankrupt in 1975.
