This app provides readability indexes for Portuguese language texts.
Based on the number of letters, syllables, words, phrases and complex words, this app informs you how difficult it is to read the text.
The degree of difficulty is calculated from the Flesch-Kincaid Education Level, the Automated Readability Index (ARI) and various other text readability formulas.
The final result is usually between 5 (high readability) and 20 (low readability).
