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:

  • Graphing Calculator Manual
  • Integral Calculator for calculus
  • 3-D Functions Plotting Calculator
  • Handyman's Calculator
  • Graph 89 - Emulator for the TI-89 of Texas Instruments
  • Math Helper Lite
  • Mathlab Arithmetic

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.

Several other educational and office type apps are presented at iTunes either free of charge or at a range of prices that include quite a few for only 99 cents.

These and other handy apps are quite useful and new apps are added to the selection almost daily.

Amazon Apps Store - Free Apps

About three dozen productivity apps, games, and utilities for Android phones or tablets are free during school supplies weeks temporarily.

Check daily for different free apps. The first set I mention would usually cost at least $100 together. They can save you a lot of money on school and office supplies. Some of the best are:

Free Science Apps

Some easy to use apps for the sciences will help students all year round.


Besides apps found on Amazon for download, Science Focus magazine suggests these free apps:

  • Earth-Now - Requires Android 2.2 or later and is produced by the NASA Jet Propulsion Laboratory. This app has a lot to do with climates across the globe and climate change.
  • Mobento. This app collects science videos from TED, Khan Academy, and other science and information sites that are accurate and respected, transcribes the videos, and provides the materials to you for free.
  • Skeptical Science by Shine Technologies Pty Ltd. Review all sides of an argument with peer-reviewed research.
  • TED (Technology, Entertainment, Design). Android 2.1 or later, by Ted Conferences

APPLE iTunes

  • 3D Brain for iPad features a rotating 3D human brain model. Select any specific part of the brain from a drop-down menu. Under "INFO" you will find substantial summaries about each part of the organ. The app also includes case studies in brain damage and diseases. Doctors and nurses should have this one! You know it's a good app, because it was produced by the well known Cold Spring Harbor Laboratory.
  • EarthViewer and The Galaxies are very useful and entertaining apps for learning about physical science and the universe.
  • Essential Skeleton - Like 3D Brain, you have a 3D skeleton. English and Latin names are provided for each bone.

  • Solve the Outbreak. This is wonderful! With the help of the Centers for Disease Control and Prevention, you can work through disease outbreak and epidemic progressions like "Doctor" Sherlock Holmes. I could have used this app in Epidemiology classes, but we were not using the Internet yet - that came the year after I graduated.
  • Frog Dissection - We did this by hand years ago, but know, you can do it with the app. It also provides labels, quizzes, and videos.

      I've wondered which apps are the best. My son started taking college classes this year and while he has a very nice calculator, it would be nice to have a back up in case he ever forgets it. Thank you!
