Duolingo is an application that helps people learn languages that can be accessed via smartphones or computers. previously I have used this application to learn Japanese. inside the app you will learn about basic sentences, simple conversations, verbs, objects and animals. because I took a Japanese course I also learned katakana and hiragana in this application. We can set a daily target of how many points should be earned in a day to motivate learners, besides that there is a weekly point leaderboard that makes learners excited and motivated to learn. This application is highly recommended for those of you who want to learn languages, even though they repeat the material which sometimes makes us bored or find it too easy to answer it precisely according to that is how we make it easy and always remember what we have learned.
