The app is simple. Random words are the best for daily learning too, provided with sample sentence(s). Kanji stroke orders are available as well. JLPT words ranging from N5 - N1. The conjugation forms for godan/ichidan verbs are so useful for me, a total beginner. It has constant ads without purchasing the premium version, which is kinda annoying. But please support the developer. The app itself works really well. Give it a try guys.
