BIGBOX is an Android app developed by Compass Publishing that provides a customized educational service to learn English through video viewing and mission-based learning. With over 10,000 videos available, including engaging content from popular providers such as Sesame Street, Badanamu, Pororo, and more, BIGBOX offers a wide range of multimedia flashcards and English expressions to boost fluency. With a game-like learning system, daily missions, and word challenges, BIGBOX motivates self-learning.

One-on-one custom video recommendations, personalized progress reports, and an AI friend named Monty who can help practice speaking and listening skills are just a few of the features that make BIGBOX a great choice for children who want to learn English. BIGBOX is a free app, but a monthly subscription of $13.99 is required to access all features. Subscriptions are renewed automatically, and cancellation is only possible by turning off the auto-renewal feature 24 hours before the next payment. BIGBOX has been recognized with several awards, including the 2019 Bett Awards Finalist, Educational Apps, and the 2018 Korea Internet Award for a Ministry of Science and ICT Award.
