Wow, I'm actually really surprised by the rating of this app. To keep it short (English -> Russia) — * Terrible in-app keyboard * No dark mode * Very buggy * Word orders are almost always wrong, doesn't allow for multiple correct answers. * Doesn't teach you case endings rules, only memorization. * Very long transition times between questions, like it's loading questions remotely. So much time wasted. * Quite expensive for what you get w/ predatory "sales" I would highly not recommend this.
