Two sources, two kinds of installs
Apple supplies spend, impressions, taps, and Apple’s tap-through installs. Qonversion supplies customers and revenue attributed by the Qonversion SDK and AdServices. These install counts can differ: a Qonversion User is an SDK-attributed customer, while an Apple Install is a console-reported conversion. CPA is spend divided by Apple installs; CAC is spend divided by Qonversion paying customers. They answer different questions. Period totals and daily chart points are also different from cohort windows. A period total covers the selected dates. A D7 window asks what customers installed on those dates earned through the end of the UTC day seven days after each install date. It does not mean revenue collected during the next seven calendar days.D0 ends at the end of the install’s UTC day; Lifetime continues to change and never closes.
Growing and Mature cohort windows
The Cohort windows setting offers two readings:- Growing (default) includes all installs in the selected period and their revenue observed so far, capped at each window’s UTC boundary. Its cost denominator is the row’s Apple spend for the period. Values keep accumulating as customers pay and Apple revises spend. Growing values are displayed plainly; there is no so far hatch or maturity legend in this mode.
- Mature counts closed cohort days only and marks windows that are still maturing as so far. A cohort day is closed once its window length plus the maturation buffer has passed and Apple can no longer restate that day’s spend. The report names the closed date range.
