What it is

Professor ARPDAU is a web service for product managers and teams working on free-to-play mobile games. Its analytics tools model retention, lifetime value, campaign break-even timing, daily active users and revenue. The retention calculator fits a regression curve from D1, D3, D7 and optional D30 observations; at least two observations are needed, while a 0% observation is excluded. The LTV predictor multiplies ARPDAU by the retention-curve total. A break-even analyzer uses CPI, observed LTV and retention metrics to estimate when cohort revenue exceeds acquisition cost. Another predictor models DAU from daily installs and retention scenarios, then estimates daily revenue with ARPDAU. Its geographical pricing tool can update in-app prices by country, with user-controlled targeting and adjustments, using Google Play Console access and Google’s API. Free modeling tools need no account.
