How it’s measured

Every opening is judged four ways, each from real App Store data.

  • Demand

    How many people already rate apps like this, in the US and UK and in the market itself.

  • Revenue

    Whether the leading apps place on the top-grossing charts, or sell as paid apps.

  • Competition

    How many established apps the market already has, scaled to its size.

  • Leading apps

    How users rate the apps there now. Weak leaders are a way in.
