Kotlin Trainer

하루에 단 몇 분의 시간이 지남에 코 틀린 유창 개발!

This app's concept is based on the pedagogical principle of spaced repetition. If you already have some programming skills and just want to pick up Kotlin, you should be able to become proficient by merely reviewing the syntax. Problem-solving practice is always necessary for a developer but it doesn't have to be coupled to practicing a new language.
