What Rheo is
Rheo is a mobile experimentation platform for designing and changing app flows without waiting for App Store reviews. Teams can build onboarding, paywall, win-back and upsell paths on a visual canvas, including branches and targeting. They can compare holdouts and variants in flow structure, copy and timing, then review conversion and revenue. Rheo says its inputs, layouts, animations and system moments render natively on iOS and Android rather than in a WebView. React Native is supported; Swift, Flutter and Kotlin are marked as coming soon. After SDK integration, teams publish flows for the SDK to pick up. Dashboard features include flow completion measures, funnel views and cohort views. Rheo Engage supports broadcasts and automations using the customer's own SES, Resend, Postmark or SendGrid account. Named integrations include RevenueCat, AppsFlyer, Adjust and Superwall. The free plan includes 400 MAU and no experiments; the Grow plan is $49.99 a month. Exceeding an included MAU quota pauses the SDK until the next month or a plan upgrade.
