Why are you replacing Lingots?

Remember how a number of users ended up with a lot of Lingots and not enough things to spend them on? This resulted in an “inflation” of the Lingot economy that needed to be addressed in order to improve the system. Gems can be earned by doing practice or purchased and provide users with more options for how they want to use and support Duolingo. On the flip side, they give users another (optional) way to support Duolingo’s mission to bring free education to the world. (Lingots are being replaced on iOS first)
