Fry Words is an Android application developed by November31 that aims to improve your vocabulary by providing you with a list of 500 high-frequency English words. The app is a helpful tool for both children and adults who are learning English as a second language.

The app has divided the 500 words into five levels and further categorized them into groups of twenty-five, based on their frequency of use and level of difficulty. The flashcard-style setting allows you to learn the meaning of each word, and the word is read out loud when the card is touched.

The app also has a Review list where you can mark cards using a star and then review them later. Additionally, you can use the long press arrow buttons to jump to the start or end of the list. The app is free to use, but the paid and ad-free versions are also available.

Overall, Fry Words is an excellent vocabulary builder that provides a comprehensive list of high-frequency English words and is a must-have app for anyone looking to improve their English language skills.
