Power up your English pronunciation of the "L" and "R" sounds with simple 5-minute lessons and reviews!

Reviews adjust themselves to your learning speed!

154 words in total!

This app is designed to help you improve your English pronunciation of the "L" and "R" sounds. The key to improvement is regular practice. Follow the daily lesson which contains audio by a native speaker, and record your own voice for comparison.

Then carry out the daily review quiz. With its SRS learning system (similar to the flashcard program Anki), it will automatically identify words that give you trouble, so that these show up more often in future.

★ Hear Native Pronunciations ★
Professional pronunciation by a native speaker has been recorded for each word so your ear can get accustomed to and master the sounds.

★ Compare Against Your Voice! ★
You can record your own voice for each word and play it back to compare with the model pronunciation.

★ Learning Engine ★
The Daily Review uses an SRS (Spaced Repetition System) learning engine, which automatically sets a review schedule for each word. As your Daily Review results improve, the period of time until the next review is gradually made longer.

★ Make a Favorites List ★
Using the “My List” feature, you can easily bookmark any words you study so that you can review them again at any time.
