The app developer, WapMeLinh Team - Nguyen Duy, is a final year student who understands the difficulties that students face when studying away from home. Many universities across the country require students to pass the English B1 exam, which is why this app was developed to help learners improve their English language skills and make test preparation more enjoyable. The app also includes features for IELTS exam preparation, English level tests with increasing difficulty, and English communication exercises. The developer encourages users to provide feedback to improve the app further.
