Good start, needs refining. I really like the concept of this vocab app. I'm not a complete beginner in my target language, so being able to choose words that I want to learn and are relevant to me instead of being forcefed a list is great. However... There are a lot of errors, and no function to report these (yet). For a lot of words the example sentences don't actually contain the target vocab word. Finally... The pricing is absolute madness for something so unpolished.

Hi! Sorry to hear that you didn't like the execution. Indeed we are working on improving the quality of translations. Already the translations in "Add Term" are very good and "Explore" is coming next. Reporting errors will follow, so that we can get the error rate down to 0%. Pricing is a relative subject :)

in general app smooth and good looking. But the price of the product from the beginning is too overpriced for unknown app. 1) I can't delete my account (prev was app cause of T9) manually. And yes, I want to do it. 2) I can't change the "my default language". 3) And the education process are really pure. Really, I added new unknown words for me and they want me to translate and type the words that was added recently. How its really possible? 4) "Free" possibilities are super small.

To delete, just long tap on the app - same process as with any other app. Right now the UI is only in English. Not sure what the problem in the 3rd point is about. Just tap the flashcard to look at the reverse side, swipe right if you remember the word and left if you don't.

It's okay, but it expects the user to do everything themselves immediately, and there is no Romaji or even furigana in the Japanese word cloud when starting out. its a good looking start to replace anki, but without a spoonfed hiragana katakana and grammar course to start it's entirely useless for a beginner. altetnatives lije Duolingo is popular because it simply gives you something to learn, like going to class every day. extemely costly for what it is, when an actual college course is 300.

Romaji and furigana are available through "Add Term" and "More". They will soon also be available in the Explore section directly. We focus on word memorization specifically, so it's not the same methodology as in Duolingo.
