About this app

Algeo is the most beautiful scientific graphing calculator available on the Play Store. It's fast and powerful and you'll never have to carry around a large physical TI calculator anymore. The intuitive interface shows your drawn functions as you would write them on paper rather than squeezing everything on a single line. And you don't need an internet connection unlike other graphing calculators, it works offline as well! Useful for calculus, physics or to solve those x+y equations.

This free app is packed with more features than a big TI 84 graphing calculator. Solve your homework with Algeo: draw functions, find intersections and show a table of values of the functions with an easy to use interface.

As a calculus calculator
• Symbolic Differentiation
• Calculate Integrals (definite only)
• Calculate Taylor-series
• Solve Equations
• Draw function
• Function plotting and finding roots of functions

As a scientific graphing calculator
• Trigonometric and Hyperbolic Functions
• Radians and Degree Support
• Logarithm
• Result History
• Variables
• Scientific Notation
• Combinatorial functions
• Solve linear equations (x+y)
• Do everything what you can do with a ti graphing calculator
• Number theoretic functions (modulo, greatest common divisor)

As a free graphing calculator
• Draw up to four functions
• Analyze function
• Find roots and intersections automatically
• Pinch to zoom
• Share your plots with your classmates
• Create an infinite table of values for a function

This graphing calculator is the easiest way to analyze a function and integrate and differentiate equations. Useful for math classes in high school or university. Take the Calculus quizzes with confidence knowing that Algeo helps with all mathematical functions. It makes integrating a breeze.

This calculator meets all of my needs as a university physics lecturer. Though I don't care for some of the more recent format changes such as the function list... it just takes more clicks to get to things like inverse trig functions. The old 3 panel format was better than anything since. But it remains the best free app calculator I've seen in a long time.

The best calculator app! So feature-full. I've been using it for just over 2 years, and really like that it behaves like a graphing calculator for all aspects, not just graphing itself. You get to enter as many things as you want on a line, and the persistent history is nice. Graphing works well. Dev is responsive. Ads are unobtrusive, but the premium upgrade is low cost (and required for complex #s). Honestly, I could name nifty things I like about it all day, but you've got the info you need.

Great calculator, obnoxious ads. They play sound and don't stop until you manually close the app. Your phone will keep playing sound for several minutes after going to a different app and you will have no idea what's doing it. The ads aren't videos, so i don't know why they need sound. Update 3/13/20: they may have fixed it, no issue recently.
