Small-size readability

• Contrast: teal mark on black fill — check both dim OLED and bright LCD.
• Silhouette budget: digital numbers, text should remain readable after the store’s rounded-square crop.
• Lettering “75 MPH KM/H” must survive home-screen size; thin strokes usually fail first.
• illustration/photo/dark detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.4/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing スピードメーター GPSナビ、速度計, not authoritative store scores.

Transferable design moves

• Keep digital numbers as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (teal), not the whole black field.
• This capture’s illustration/photo/dark vocabulary transfers best when the same restraint is applied at export size.
