Incredibly useful and has nearly everything. Can't find much reason to use anything else (This is by far better, and cheaper, than Duolingo). A suggestion, or two, I have is adding a quiz function, similar to verbs, to adjectives. Although its not the biggest thing it does help cement adjectives/verbs into memory if you are repeatedly conjugating them in a quiz. 2nd is for vocab I am quizzing to display only the kanji I have learned thus far. Makes it easier to learn in parts.

JA Sensei is one of the most detailed and helpful applications to help you learn Japanese. Mostly beginner friendly. If you struggle with any sort of learning disadvantages, the layout may not always be friendly as it can be both over and under stimulating. JA is especially helpful for anyone with strong self-motivation. There are numerous resources in one place, and if you do purchase the upgrade, it has a more than fair price for lifetime access.

I think this is an amazing app for a dedicated student interested in learning quickly. Being able to turn off romaji forces you to become quick at reading and looking at all kanji in depth really boosts it's value. There are not other apps that offer that much control. Also, everything is easy to find. The explanations are clear and there is still so much room for growth. Can't wait to get more updates! (more verbs and explanations/examples for phrases and particles please!) Still worth every $!
