iSolve

This is my first android app.
I couldn't find a single app on play store to solve n-dimensional simultaneous equations which I sometimes find use for so upon learning to write code for my smartphone, I implemented Cramer's rule for the job. The main engine of this part of the program here is finding the determinant of any square matrix which is done via recursion.
The other component of iSolve is the Polynomial Solver which is an android translation of RootFinderC.
This app has some bugs but is functional.

Added estimation by Bisection Method.

WordMaker X

This is a new version of Word Finder. Because searching for subset words in a wordlist is so much faster than generating and checking different permutations of the seed word, the save feature has been removed with a few modifications to the interface.

Word Finder

A program that finds out what words could be created out of a given seed word. For example: if you are given 'leghorn' as your seed word, other sub-words that can be created out of it that are of length greater than 4 are:
lore
lone
long
ergo
glen
goer
gore
gone
hero
hole
horn
hone
ogle
ogre
oner
role
noel
loner
enrol
heron
longer
Progress can be saved using the 'Stop' button into a config.inf file that will be generated upon a click.
For resuming, the config.inf file should be in the same directory as the main program executable. In this case, the 'Make words' button functions as the resume command. For the operation to begin from where it was left, the program generated config.inf file and the new-words-list text file must be present in the program's directory or else, in case of absence of config.inf the operation will begin from the start and in case of absence of the new-words-list text file, the process will resume from the last word it found out and write it in a new new-words-list file.
