Writing
Hangul first, then a story.
The alphabet lessons exist because Remember has a real job here. After that, the app should spend your hour on a page.

You cannot read Korean if you cannot see the letters. That is not a philosophy. It is a door.
So Inlet Language has eight short Hangul lessons. They are optional if you already read. They are required in practice if you do not. Skip them the moment you can hear a syllable and find it on the page.
That block of work is Remember. We kept it because an alphabet has to be recalled before a story can ask anything else of you.
Once the letters are there, home is the feed. A new text, a few unknown words, audio for the line you are on. Using a word you met yesterday inside a page you have not seen is a different job from tapping a flashcard.
We still let you tap. Meaning and sound sit in a sheet under the word. That is a gloss, on purpose, so you do not leave the story to go look something up.
The five questions after a text are a check, not the product. If those questions were the home screen, we would have shipped a quiz with a reading skin.
Hangul first, then a story, is the order we would defend to a skeptical teacher. The letters get a short, skippable course. Everything after that assumes you can see the writing and need a page at the right unknown rate.
Japanese and Spanish open in the same reader. They do not get a second Hangul course. A learner who already reads goes on to the same feed.
