Apphud vs Professor ARPDAU

Apphud provides subscription infrastructure and analytics for in-app purchases on iOS and Android. Its SDKs support iOS, Android, React Native, Flutter and Unity, and the service includes web access and an API. Teams can manage in-app purchases and auto-renewable subscriptions without server code. The dashboard reports subscription measures including MRR, retention, churn, ARPU, trial conversions, proceeds and refunds. A/B experiments let teams test purchases and paywalls, while Apphud says it validates App Store and Google Play receipts without server code. Integrations include analytics, attribution, messaging and notification services, as well as custom webhooks and APIs. Apphud Rules can offer discounts to retain or win back subscribers, but Rules are iOS-only. The free plan includes one seat and $10,000 MTR; after its grace period, renewals stop being tracked and dashboard access is unavailable. Pro costs $49 a month and includes five seats and online chat support.

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.
