A free program for Android, by Eductify.

Learning to spell and understand grammar is essential for speaking and writing well. This is especially true for English, the most spoken language in the world. We have developed a program to help you with this process. The app is designed to be used by children and adults alike.

The app is divided into different sections. The first section contains a series of games that can be used to practice and improve your spelling and grammar skills. The second section contains a series of quizzes that can be used to test your knowledge.

The third section contains a series of lessons. Each lesson contains a complete explanation of a concept, which can be used to learn more about grammar.
