A new app was made by a high school student disenchanted by the methods for success used by the folks at Quizlet. They didn't think that a "dark mode" should be hidden behind a paywall, so they decided to take action. The result is an app that, as one Reddit user said, is "lightweight, looks aesthetically pleasing, has fluid animations, has a dark mode, and just plain works with no fuss? And you released it for free?" It's like a rare unicorn, really.
