Review summary

GeoGebra CAS Calculator on Android offers a strong mobile CAS experience with graphing and a clean UI, and is free and easy to start. However, reviewers repeatedly report saving/sign-in troubles, input/navigation frictions, bugs and performance issues, and limited support for advanced mathematics or step-by-step solutions, making it less ideal as a desktop replacement.

Pros

Feature-rich mobile CAS with history, copy/paste, pretty print, solve, and variables.
Graphing capability that shows plots of expressions.
User-friendly, aesthetically pleasing GUI and intuitive UX.
Free to use and easy to get started.

Cons

Saving and sign-in problems and nag prompts to save, including limitations on offline saving.
Input and navigation friction on mobile: awkward keyboard, cursor navigation issues, and backspace/back button bugs.
Bugs, stability and performance issues: frequent bugs, rendering glitches, and slowdowns after updates.
Limited capabilities for advanced math and absence of step-by-step solving or detailed answer views.

2025-07-13	Ma*****	Undoubtly Geogebra doesn't need further presentations, and this is probably the best CAS you can install on a mobile (if you need do more serious things, turn on computer and, Geogebra is not renamed as a CAS for professional mathematicians) , HOWEVER, I dislike so much that is almost disappeared the possibility to save offline the own works. Come on guys, this is a mobile app, it is not used for making reasoned works to share online, I use it while playing at racing games XD

2024-11-27	M *****	At first glance it looks very promising but rearranging equations (my very first test) 60x^2 * (x-5) - 30 showed up as the end result instead of 60x^3 - 300x^2 - 30 (like every CAS calculator TI or HP does - of course I want the x^3 form). With "solve(y=above equation,y)" it works but it should work all the time. Why is the app (and online too) doing this? Ok. With expand() it works. I'm getting used to it.
