Anglické Fráze trial is a free mobile app developed by Apps4English that offers an efficient way to learn and practice English phrases for everyday use. The app uses the intelligent repetition method, also known as the flashcard method, to help users learn and retain new phrases. The app analyzes the mistakes made during practice and displays problematic questions more frequently than the ones already mastered. This helps to speed up the learning process and eliminate the problem of forgetting.

The trial version of the app offers 14 free sample lessons, while the full version includes 146 lessons with 1900 questions. Each lesson contains approximately 10 questions, and users can choose which lesson or question they want to learn. Users can pause or restart learning at any time, and the app provides overall statistics and graphs for each question. The app uses a sophisticated algorithm based on the spaced repetition technique to plan repetitions, and it displays problematic questions more frequently than the ones already mastered. The app also regularly updates and adds new lessons and questions. The app's interface is optimized for both phones and tablets.
