Thousands of entries and example sentences, generous handwriting recognition, references out the wazoo, helpful study tools, and works offline - in 2011 these were the reasons why this app helped me as a student and struggling speaker of Japanese. Now, as a professional translator, this app is STILL my go-to reference (the only thing more helpful is a Japanese language dictionary). Split view and text reader features are crazy helpful. It's truly the bee's knees.
