How AppTrendKit gets its numbers
Several times a day we record where every app sits on the App Store's Top Free, Top Paid and Top Grossing charts around the world, and we follow its ratings, price and how it makes money. Our models turn those signals into monthly download and revenue estimates for every iOS app.
Each estimate is one rounded figure with a confidence level. Where the evidence only supports an upper limit, the page says so with a sign, for example <$5K, instead of inventing a precise number. Revenue means what users spend in the App Store, before Apple's cut.
