Awesome premium features
I use this app on my iPad in my class all the time and really recommend upgrading to premium to access the text-to-speech, better translations/dictionary and reader mode. With so many language learning apps out there, this app is a hidden gem.

Essential for Learning Japanese
I have only recently started learning Japanese, but I have found Kaku to be essential in keeping myself immersed in the language everyday. The grammar examples have helped me to understand and work with various conjugations and special word forms. The selected words make Kaku easy to use in quick situations. A lot of love and care has gone into this app. If you have any inclinations in getting the app; do it! It is wonderful to use on a daily basis, and I know it will continue to help me in my language learning journey for a long time.
