The Japanese language is a big part of world culture. A large number of people around the world are interested in it. Sometimes it seems that it is rather difficult to learn, because it has a unique writing system. But for true connoisseurs of the language there are no barriers! And, as you know, if you start learning a new language from the basics, then learning any language will be quick and effective. Since Japanese numbers are one of the main components of the language, we have created a very handy new application that will help you quickly master them. Thanks to a special algorithm, you can quickly learn Japanese numbers and bring them to automatism. Our new technique using mathematics and logic will appeal to all people who like to think. But for fans of conventional tests, there is a lot of interesting things here. So, our application contains: - learning numbers tests. These are classic tests for learning numbers. But they have one peculiarity. Before starting the training, you can choose the form of writing the number (digital or alphabetic). And of course, for your convenience, you can select the range of numbers you want to study. - quick tests. In this type of tests, you can select the range of numbers to study and immediately start the tasks. This type of test is suitable for those who want to quickly check their knowledge or repeat certain numbers. Thanks to the fast work of the application, you can train in your free time without wasting a minute. - math tests. Our algorithm will provide you with a math problem. You need to solve it and write down the answer in the special field. Before starting the training, you can choose the form of recording the task and answer and a mathematical operation (addition, subtraction, multiplication, division). Once you start using this type of test, you will understand all its usefulness and uniqueness. And most importantly, you will quickly feel the results. - logical tests. Here you have to continue the sequence of three numbers. With the help of logic, you must find the fourth number and enter it in the answer field. Before starting the training, you can also choose the form of recording the assignment and the answer. The use of mathematical and logical tests will be useful to everyone, regardless of the knowledge of mathematics.

While memorizing words, the frequency of lesson is more important than duration of each lesson. 10 minutes on each day of the week will be more productive than one hour of tuition a week.

So you no longer need to search for free time to practice Japanese! Simply, once you get a chance, launch the app and do one lesson at a time =) Short sessions will not affect efficiency of word memorization.

Additionally, in the settings you can choose between male or female voice. Dynamic lesson difficulty - The app changes lesson difficulty gradually as you progress. To achieve this, it keeps stats for EVERY word! Example: in the spelling mode, initially you need to insert several missing letters in a word, then create a word having extra letters and finally, when you are ready, you will need to type the entire word on the keyboard. Modes for quick learning - The App includes four additional lesson types which are made of Favorites, Difficult, Old, Random words. You can add any word to your favorites and later create custom lesson from your Favorite words. Words are automatically added to "Difficult" (the ones you struggle to memorize) and "Old" (which you have not reviewed for a long time) sections. A "Random" mode will create a unique lesson. Do not need to know how to read - If you cannot read yet, no problem! Each word has a transcription in your language! And for more experienced ones, in the settings, you can choose a phonetic (like in a dictionary) transcription. Additional features - Thanks to your reviews, we are constantly updating the app to make it better! To help you take care of your eyesight, with just one tap, you can activate dark theme. If you temporarily do not have internet access, no problem! The App can work offline as well! Review Past Material - Many good apps do not pay enough attention to review past material! For this purpose we created the word game "True or False". It is very simple, but it's addictive and the most importantly, it helps to repeat past material and never to forget it!
