Great app for practicing Japanese with live translations and grammar examples, especially if you have an iPad and keyboard. From the App Store description:
Do you wish you had an app to double-check your Japanese sentences before you post them on social media? Have you been using an old notepad to work through your Genki textbook exercises? It's time to throw it out because Kaku is a note writing app for beginner to intermediate Japanese learners.
It combines a number of different tools all into one app:
An offline translator that translates as you type to give you live feedback on your sentence structure
Dictionary look-up on highlighted words so you can check you have used the correct word on the fly
Common word lists across many categories that come in handy when you keep getting words like aunt and grandmother mixed up
Grammar examples from the popular Tae Kim's Grammar Guide that provide a template for your sentences
Saved sheets that sync between your iPhone and iPad so you always have them with you
Reader Mode that improves readability on larger devices
Clipboard auto-translate so you can copy any text snippet on the web and quickly see what it means
In addition, users can upgrade to Kaku Premium which gives access to exclusive translation services:
Text-to-speech audio translation which highlights the text being spoken so you can shadow read and improve your pronounciation
Advanced Translator which uses a cloud translation service for more accurate translations
