The application provides the list of words in Estonian language varying from A1 to B1 levels. The main goal of the application is to allow users to exercise basic forms of words like genitive and partitive cases for nouns and adjectives, or -da/ta and third person singular forms for verbs.The user can search new words, mark them as favorite to add them to their vocabulary. Later on they can do exercises that include words which they have added to their vocabulary. At the end of the exercise you get a feedback that shows number of mistakes made, skipped and correctly-typed words.No internet needed to use the application. The list of words is kept offline so you can enjoy exercises anywhere and anytime you wish.Acknowledgments:Special thanks to the Institute of the Estonian Language for providing the list of words with their main forms.Icons made by Freepik from www.flaticon.com
