ルミナス 英和・和英辞典

For those teaching English to Japanese native speakers, or testing English ability, it is important to know what English words and usages Japanese are expected to know by grade level. On the Apple Japan app store there are worthy competitors such as "Genius," but on the US app store, this is the only app that can handle the task. Multiple meanings are provided where appropriate. The one shortcoming of all apps in this genre is that none indicate words that Japanese will know because it is used as a foreign loan word rendered in the katakana script in Japan. If any of these competing dictionaries want to up their game, this is the facet in which the opportunity remains.
