Scientific calculator plus 991 (advanced.scientific.calculator.calc991.plus) is listed under Education on Google Play.
AppIconVault stores the icon as a dated artifact so a later redesign can be compared against this version instead of disappearing silently.
Play icons ship as square 512px masters and are masked by the launcher, so safe-area padding matters more than on iOS, where Apple applies a fixed rounded-rectangle crop. Icons that read well in both stores usually keep the identifying mark inside a generous central circle.
