Questions
What size should an app icon be?
For iOS, one 1024 × 1024 PNG — Xcode generates the rest. For Android, a 512 × 512 Play Store icon plus adaptive icon layers at 108 dp. For the web, an SVG plus a 180 × 180 apple-touch-icon and two PWA icons.
Do I still need a 20-file favicon pack?
No. An SVG favicon, one multi-resolution .ico, a 180 × 180 apple-touch-icon and two manifest icons cover every browser in use. The rest is legacy weight.
