I've been having success with WaniKani. It's mainly for vocabulary learning, but just that lets me be able to read enough to be able to start picking up the grammar from context, and (more importantly) being able to apply that grammar in more situations which makes it much easier to learn. It also forces you to rapidly become fluent in hiragana (IIRC romaji isn't used anywhere). I feel like it's working because I'm frequently understanding the terms in real Japanese content, and it's giving me the ability to understand terms that haven't been explicitly taught (e.g. I was reading something the other day and read 心理学校 and 火の用心 as "psychology school" and "beware of fire" [with the correct pronunciations/readings] without any thought, despite never coming across the phrases before). > DuoLingo will bring you to 15% understanding of Hiragana before dumping you into Katakana Personally that's how I prefer to learn -- I got to being able to read about 50% of the hiragana without too much effort then went straight to WaniKani, and found I was making much more rapid, reliable (i.e I feel like I'm actually _reading_ them, not just being able to remember the meaning/having to think about it) on the remaining 50%, and I've mostly learn the katakana through context/use -- but of course YMMV.
