AnalyzeText is an app which can aid in cryptography, determining authorship of a document, assessing reading level, and more.
It analyzes frequencies and averages of letters, syllables, words and sentences. Furthermore, it determines reading level according to three popular scales. Any or all of the results can be viewed and/or saved as text files in the root SD card directory or elsewhere. The SD card may be written to or read from but no files are deleted. There are several methods of transferring these text(.txt) files to or from computers or to printers, including use of Dropbox, Cloud Print and other apps. AnalyzeText has been tested on Android 2.2.
