Small-size readability

• Contrast: white mark on purple fill — check both dim OLED and bright LCD.
• Silhouette budget: circle, mountain, sun, cloud, ribbon should remain readable after the store’s rounded-square crop.
• Lettering “PRO” must survive home-screen size; thin strokes usually fail first.
• Internal usability score for this capture: 0.6/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing 高度計 Pro: 標高, 方位磁針, バロメーター, not authoritative store scores.

Transferable design moves

• Keep circle, mountain, sun, cloud, ribbon as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (white), not the whole purple field.
• This capture’s graphic vocabulary transfers best when the same restraint is applied at export size.
