Bunpro Japanese SRS

Better than Duolingo. I went looking for the mobile app after using the website and it changed my whole experience, the lessons are suited to your needs (I matched mine up to a textbook I own) and practice is actually critical, which is what I was weakest at before. There are too many features to list but the service is worth it even though I'm not a fan of subscriptions The grammar descriptions are roundabout but they explain grammar relationships properly instead of dumbing it down

It's a great app to just keep grinding grammar. It's a bit unwieldy sometimes and I wish the SRS system was like Anki's. But it's cheap subscription $5/month is worth the content and I go back to it a lot for a comprehensive explanation of a grammar point. I went from half way point of JLPT N5 to now at the half way point of N3. it's good!

1 month free trial without needing card info already deserves infinite praise, but even more than that the service is genuinely worth every penny if you're planning on sticking to it! It's great for drilling your recall skills, but I wouldn't use it by itself. Pair it with Anki (free app) and your choice of active immersion for best results. Halfway through N5 and making faster progress than ever.
