The model, not the sticker price
Monetization Mix
Upfront price is nearly extinct — most search results are 100% free apps, and the money is all happening inside them. This shows how the 25 apps you share a result with actually charge, and what a download is worth to each.
Why not just compare prices
Because there are almost none left to compare. Sampled live, a search for “pdf scanner” returned 20 apps and none of them charged upfront; “weather” returned 22 and none did; “calculator” returned 23 and exactly one did. A price chart of that is a flat line. What separates these apps is whether they sell anything inside, and how much a download ends up being worth.
Pair it with the rating benchmark — reach without ratings and reach without revenue are different problems.
