About the portfolio sum
The portfolio sum adds the low (P10) and high (P90) ends of each listed app's 80% band for its recorded estimate period. It is a modeled sum of gross in-app spend on App Store, not KnowledgeBox's company revenue: it leaves out ads, web sales, other stores and profit, and the sum of the bands is wider than an 80% band of the total.

How these estimates work
Revenue is modeled gross in-app spend (in-app purchases and subscriptions, in US dollars) for the recorded estimate period. Recent estimates cover a rolling 30-day interval; older estimates may cover a calendar month. A missing start date is not inferred. It excludes advertising revenue, web sales and net profit. Downloads are modeled for the same recorded period. Both are worldwide model estimates from public App Store and Google Play signals, not reported figures and not country-level numbers.
Every figure is an 80% band (P10 to P90): the model expects the true value to fall inside it most of the time. Apps below roughly 5K per estimate period show as “< 5K”, and a figure the model did not produce shows as “Not estimated”, never as zero.
