Praise for the iOS and Android applications:

Outstanding App - ★★★★★
This well organized and functional app is a convenient way to carry and use the best kanji learner's dictionary on the market. Highly recommended. The updated KKLD is simply the best. The attention to functionality both in dictionary structure and in choice of content such as example compounds, unusual readings, and reminders about easily confused characters is simply the best I've ever encountered. The passion and hard work of Jack Halpern and everyone on his team are evident in every aspect.
