Small-size readability

• Contrast: white mark on blue fill — check both dim OLED and bright LCD.
• Silhouette budget: envelope, target should remain readable after the store’s rounded-square crop.
• Lettering “Bills” must survive home-screen size; thin strokes usually fail first.
• illustration detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.6/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing 請求書モニタ Pro, not authoritative store scores.

Transferable design moves

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