What is PariDroid?

PariDroid is a port of the PARI library to the Android platform with a simple GUI application which enables the user to call PARI functions and view the output.

What is PARI/GP?

PARI/GP is a widely used computer algebra system designed for fast computations in number theory (factorizations, algebraic number theory, elliptic curves...), but also contains a large number of other useful functions to compute with mathematical entities such as matrices, polynomials, power series, algebraic numbers, etc., and a lot of transcendental functions.

PARI is a C library (C++ - compatible). Writing C (or C++) programs, and linking them to libpari is the only way to access the full set of PARI routines (you can install most of them under gp, but this is not as portable). It will produce much faster code for low-level applications.

gp is an interactive shell giving access to PARI functions, easier to use. Low-level scripts are typically 4 times slower than directly written C code. High-level scripts, whose running time is dominated by a few calls to PARI functions, incur no penalty.

GP is the name of gp's scripting language.
