How to use this prompt

One symbol, lots of padding — an app icon is judged at 60 pixels on a home screen, so a single bold equals sign with generous margin stays legible where a full calculator keypad turns to mush. Keep the light source named and singular ("soft top-left"): consistent lighting is what lets this icon sit in a matching set later without one tile looking lit from a different room. The gradient should run corner to corner, not centre-out, so the tile reads as a solid object rather than a glowing orb. If it looks dated and plasticky, swap "glossy" for "soft matte" — matte 3D has aged far better than the old gloss-bubble look.

Variations to try

  • Dark mode — "the same icon in charcoal with a mint equals symbol" to ship both themes
  • Matching set — "percent, plus and divide symbols in the same tile and lighting" for a full utility-app family
