Cleanup：スマホ写真をかんたん整理！

Why this icon holds up

The Cleanup：スマホ写真をかんたん整理！ icon captured on 2026-08-11 needs to read as a Utilities product in a crowded App Store grid. Strong icons usually commit to one silhouette idea, limit detail that collapses at small sizes, and keep brand color concentrated enough to survive neighbors with louder artwork.

This version is stored as a dated artifact so designers can compare what changed later — not just admire a current screenshot. No earlier vault capture exists yet, so this page is the baseline for future diffs.

Small-size readability

• Shape: rounded-square crop should still leave a recognizable core mark.
• Contrast: foreground mark versus fill needs to survive dim OLED and bright LCD.
• Detail budget: fine lines and tiny type typically fail below home-screen size.
• Color count: fewer dominant hues usually scan faster in a dense grid.
• Metaphor clarity: one idea beats stacked metaphors when the thumb is skimming.

These checks are practical references for designers reviewing Cleanup：スマホ写真をかんたん整理！, not authoritative scores.

Transferable design moves

• Anchor the mark to a single geometric mass before adding ornament.
• Reserve the loudest color for the identifying shape, not the whole field.
• Design the 60px mental model first, then enrich the 1024px master.
