There is so many different kinds of gamification. It can be with apps, games, and something that can be learned with the guarantee that people can accomplish and achieve a curtain goal. I decided to explain more in-depth about Duolingo. Duolingo is an app where people can go and learn many languages like German, Spanish, French, and even English. As Duolingo is trying to help teach the user they use trivia games and puzzles to help teach people. However, when the user is learning there is levels that they have to accomplish to move on to the next level of the language. If the user isn't doing so well and is getting the questions wrong Duolingo will ask the user to take a break and come back later once they have learned the vocabulary. Duolingo starts off with very easy levels to introduce the language to the user. The levels get harder and harder, and they add more words and phrases, this makes it harder for the user to keep moving up. I think some concerns are that people will get to a point where they can't learn/understand the informations and will have to give up. I have played/ used Duolingo before; I have used it to help me learn some German phrases so it would help me understand some of the people. I liked the leveling up, but I gotta a point where I was unable to keep leveling up; overall the app is great.
