Read stays a clean full-screen feed with one white card at a time. Marks under saved words fade as each word ripens. When you page past a word you're learning without tapping it, its underline glints once. Nothing on screen explains why a card is here.
Marks by stage
経験 was saved today: a warm wash and a thick line. 思い出せなくても is Learning: a lime line. 忘れない is Strong: a thin leaf line. 一度 is Known: plain text, like any word you can read.
A glint as it leaves
You paged past 思い出せなくても and 忘れない without tapping. Each line glints once with a soft tick, then never again that day. Behind the scenes it informs ranking. It is never a grade on screen.
Tune answers with the card
Pick More like this and a stamp lands on the card, it pages away, and the next card follows your cue. Beginners can also switch on small meanings under new words right here.
Listen, Understand, Tune. Nothing else crowds the card.
