Small-size readability

• Contrast: black mark on white fill — check both dim OLED and bright LCD.
• Silhouette budget: clock face, numbers, hands, colored sectors should remain readable after the store’s rounded-square crop.
• Lettering “0 1 2 3 4 5 6 7 8 9 10 11” must survive home-screen size; thin strokes usually fail first.
• Internal usability score for this capture: 0.2/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing スカイダイビング　高度計, not authoritative store scores.

Transferable design moves

• Keep clock face, numbers, hands, colored sectors as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (black), not the whole white field.
• This capture’s monochrome/black-and-white/detailed/light vocabulary transfers best when the same restraint is applied at export size.
