What it does

  • The app’s Check the numbers screen: a sign’s photo with a box on each number it read, and the numbers listed below it to check

    The camera reads the numbers

    Passenger mode boxes every number it can find. You check them before you start.

  • A sign in the app: its photo, its math on a green plate, who found it, and a heart

    Find another way

    Every sign can hold more than one way. The keypad has square roots, powers and stacked fractions, and says “It works” when it does.

  • The app’s Home, sorted by Popular, with a sign’s photo and its math

    Popular and nearby

    See what others found, heart the good ones, and earn badges for the road.
