WordFinder.

Use this app when you want to search such as "Words that contain these letters.", "Word which doesn't contain these letters."
Setting several conditions, 'WordFinder' can guess the words due to calculation using original algorithm.
Dark-Light theme, high-context mode, and multi-language are supported.
And most remarkable what this app can is sorting words by their frequencies.
Frequency refers to the level of how many times we usually use it.
At least, on a word-guessing game, I've won almost 100 times with no mistakes using my app.

But nothing is perfect.
This app also may cannot result specific word because prepared dictionary in the app are included only 100,000 words, despite total number of whole English words are considered to be more than 1,000,000.(The number of English words, in other hands, we usually use is at most less than 30,000)
But for such a time, I implemented "Deep search" system differentiated from normal search algorithm.
Utilizing this system the app can result any words which iOS built-in dictionary has its definition.

This app is developed and designed by a Japanese teen programmer.
