Best thing since mindsnacks

So far so good, great way to refresh knowledge while waiting for Anki Flashcards to refresh. Or between classes to build vocabulary

Fun and Effective!!

As someone who has ADHD, the basic, textbook learning apps are really draining and hard to stay motivated with and ultimately I haven’t learned as much. But with this apps game like system, I find myself very engaged and actively coming back to complete more levels!! And the learning method is fast, so I don’t lose focus and move on to something else! Very efficient too and enjoyable, I hope to learn lots more!!
