Small-size readability

• Contrast: blue mark on white fill — check both dim OLED and bright LCD.
• Silhouette budget: rounded bars, sound wave should remain readable after the store’s rounded-square crop.
• Internal usability score for this capture: 0.4/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing AI英会話スピーク - スピーキング練習で発音や英語を勉強, not authoritative store scores.

Transferable design moves

• Keep rounded bars as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (blue), not the whole white field.
• This capture’s gradient/light vocabulary transfers best when the same restraint is applied at export size.
