LingoDeer and LingoDeer Plus are two separate apps that offer different learning materials and features:

• LingoDeer is our primary app with the core bulk of our courses. It focuses on grammar along with vocabulary and breaks down complicated concepts into bite-sized lessons, which can help our users fully understand their target language outside the classroom. It aims to bring a complete beginner to the intermediate level.
• LingoDeer Plus is a supplemental app designed to strengthen our users' memory and grasp of their target language through a series of interactive games.
