  To track revenue from a user, call [[Amplitude instance] logRevenue:[NSNumber numberWithDouble:3.99]] each time the user generates revenue. logRevenue: takes in an NSNumber with the dollar amount of the sale as the only argument. This allows us to automatically display data relevant to revenue on the Amplitude website, including average revenue per daily active user (ARPDAU), 7, 30, and 90 day revenue, lifetime value (LTV) estimates, and revenue by advertising campaign cohort and daily/weekly/monthly cohorts.
