If you wish to learn grammar, especially more advanced grammar not grammar that is often not covered by many of the more popular "JP Learning Guides" online I highly recommend imabi.net I have a very negative view of most language learning apps. Learning a language is more than vocabulary memorization and memorizing phrasebooks which is what most language apps devolve into. Consume JP media, use Anki to help build vocab/memorize kanji, and study grammar from a book dedicated to explaining grammar and not a "generalist" book that tries to dip its toes into everything.
