WordSearch 4 Lite is an app that lets you create word search puzzles. Those are the puzzles that you often see in the newspaper. The app is free, but there is a paid version that doesn't limit the size of the puzzles that you can export and print. The first thing that you have to do to create your puzzle is add the words you want it to contain. For each word, you can add a clue. You don't have to, though.
The first window that appears when you start the app is where you create your puzzles. It consists of two columns: one for words and the other one for their respective clues. You can sort your words in many different ways and even use the search feature to easily find words. After you are done with adding words, you can generate your puzzle by clicking on "Create WordSearch". The next window that appears will contain your puzzle, along with some advanced options. Here you can change the size of the word search puzzle, set the minimum and maximum word length, change the font size used and set the directions in which the words can be placed (diagonally, vertically, or horizontally). After you are done, you can either print or export the puzzle.
