What it is

Rheo is a mobile platform for designing and changing app flows, then comparing variants without waiting for App Store reviews. Its canvas supports onboarding, paywall, win-back, and upsell journeys with branches and targeting. Teams can test holdouts and variants in flow structure, copy, and timing, and review conversion and revenue. Rheo says its inputs, layouts, animations, and system moments render natively on iOS and Android, not in a WebView. React Native is supported; Swift, Flutter, and Kotlin are marked as coming soon. After SDK integration, teams publish flows for the app to pick up. The dashboard includes flow completion measures and funnel and cohort views. Rheo Engage handles broadcasts and automations through a customer's SES, Resend, Postmark, or SendGrid account. Integrations named include RevenueCat, AppsFlyer, Adjust, and Superwall. Pricing includes a free plan and paid plans from $49.99/mo. The free plan includes 400 MAU and no experiments; exceeding an included MAU quota pauses the SDK until the next month or an upgrade.
