Small-size readability

• Contrast: white mark on blue fill — check both dim OLED and bright LCD.
• Silhouette budget: tennis racket, wifi signal, microphone should remain readable after the store’s rounded-square crop.
• illustration/photo 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 RacquetTune - ストリング テンション, not authoritative store scores.

Transferable design moves

• Keep tennis racket, wifi signal, microphone 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/photo vocabulary transfers best when the same restraint is applied at export size.
