Adapty vs Professor ARPDAU

Adapty is a subscription revenue platform for app teams, combining purchase infrastructure, paywalls and onboarding flows, analytics, experiments, and user acquisition tools. Its SDK and backend validate purchases, keep subscription access synchronized across platforms, and stream normalized revenue events. A browser-based builder creates paywalls and onboarding flows that can be published without app updates, with drag-and-drop editing, templates, localization, and AI agent support. Teams can test pricing, paywalls, and flows using A/B tests with custom traffic splits, unlimited variants, and early winner predictions. Revenue analytics include MRR, churn, ARPU, conversion, funnels, cohort analysis, and predictive LTV. One-click integrations can send subscription events to analytics, attribution, and advertising services. SDKs are listed for iOS, Android, React Native, Flutter, FlutterFlow, Kotlin Multiplatform, Capacitor, and Unity, alongside a Web API. Web payments can use Stripe, Paddle, or a custom setup. Adapty supports attribution through MMP data or its own attribution, with Apple Ads attribution included out of the box. Its Pro plan is free below $5K/month in earnings, then charges 1% of monthly revenue after passing that threshold. Enterprise pricing is custom.

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.
