I've been studying Japanese on and off for a while, and most quiz apps leave you knowing whether you got something right or wrong but not understanding why. Raisu fixes that. The fact that it breaks down all four answer choices after every question is a game changer: you're not just drilling, you're actually building comprehension.The adaptive system is the other thing that sets it apart. It notices what you're weak on and keeps coming back to those gaps from different angles, which is how real retention works. The readiness score is a nice touch too, giving you one clean number that tells you where you actually stand instead of vague progress bars.Daily 5-question sessions are easy to stick to, and the streak mechanic gives you just enough of a nudge to keep showing up. Covers N5 through N1, so it grows with you. Highly recommend for anyone serious about passing the exam.

I’ve been using DuoLingo for a while thinking I’m learning a lot, but after downloading Raisu, I was humbled at how much more I need to learn to be able to ace the tests. This is a great app to get you closer to passing the exams!
