Small-size readability

• Contrast: white mark on green fill — check both dim OLED and bright LCD.
• Silhouette budget: telephone handset, text should remain readable after the store’s rounded-square crop.
• Lettering “REC” 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 コールレコーダー:レコード音声通話, not authoritative store scores.

Transferable design moves

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