Decent Its a decent app but all you're really doing is memorizing the symbols. For this to be effective it needs a few things. One thing that most people overlook on learning a different language is the vowels and sound of the letters themselves. Needs a voice imputed and native speaker option along with a romanji option so people can get an idea of what the word actually is.
Lacking voice I really like the interface simple and informative, would give 5 star if there's voice example
Thanks! Simple, useful, free, with no ads and no permissions~ just awesome :) I do wish the question text was bigger; the bolded kanji can be hard to read at that size. But whatever, great app!
Mixture of correct and incorrect Some of the kanji shown with the vocab words are incredibly outdated or just not used. For example, for "kuru" ( to come) an alternate kanji is provided that hasnt been used since the early 1900s, according to my mom, a native japanese speaker. Also, some of the readings are wrong, like at one point they put kanata instead of heta, as well as the wrong meaning. The meaning and reading shown may be correct, but the kanji wasnt. It works, but the amount of errors makes me a little wary while using it.
Simple, clean, ad-free, useful This app only tries to do one thing, and does it well. having access to various categories, subdivided in small batches, is cool because it allows you to work on small sets of words, learning them progressively. The interface is simple, efficient, and the progress bar visualization gives you a good and motivating way to look at your results, encouraging you to go further and keep expanding your vocabulary. It is not a dictionary app, yet it comes with a few sample sentences to help you understand in which context you may encounter a word, which is a neat addition when you are learning a word.
Wow I've used a ton of these apps for studying Japanese. I study on the train, waiting in line, on the toilet, etc. This is one of the best ones out there. The vocab is perfect and I love the categorization for JLPT and word frequency. Best part is the app requires no permissions! Well done. I'd easily have paid for this app. The quizzing is no nonsense and giving both English and Japanese answers as an option is wonderful. I can't think of any improvements yet as I've only used it for about a day, but I will!
Kotoba-chan is now open-source!
As I do not have time for development I am opening up the project. Feel free to make changes to the code/database!
