I’m a native Russian speaker, so, for me there are two irreplaceable dictionaries I use daily, one of which is RU to JA, and the other one is this amazing and FREE app. I loved it a bunch the moment I’d installed it. The design is clear, features like lists and searching by keys are pretty handy, and the app’s vocabulary includes modern, archaic, and specialized words. Thank you so much for packing the app with all these useful sentences which make context clearer for users.
