Basic usage

1. Select the numbers that you want to learn and if you want to find the Hangul form from the number, to find the number from the Hangul form, or both. Try to enable only one category of numbers that you don't know well, this way you will learn progressively. You should also learn them in increasing order.
   
2. Press the
   GET QUESTIONS
   button to start answering questions. If the button is disabled, either the app is still loading (there is a colored spinner under the button) or there is no category selected in the settings.
3. When a question appears, think of the answer in your head (or write it down). Then reveal the answer by pressing the
   SHOW ANSWER
   button (or the keyboard_arrow_down key on the keyboard). Finally, say if you had found the answer (
   FOUND IT
   button or keyboard_arrow_right key) or if you didn't (
   ASK AGAIN SOON
   button or keyboard_arrow_left key).
4. When you feel like you get it right all the time, add new numbers by accessing the settings menu again (settings button or keyboard_arrow_up key).
5. Repeat this until you know all of them!
