HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (315 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.4 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.
