Rheo vs Slickplan

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.

Slickplan is a collaborative website-planning suite for content and UX teams, delivered through the web with API access. Its tools include Sitemap Builder, Diagram Maker, Content Planner, and Design Mockups. The Sitemap Builder’s AI assistant can generate site maps, refine structure, and improve page labels in multiple languages. It can crawl an existing website and import URL, XML, or TXT files. CMS plugins transfer structures, content, navigation, and SEO elements to WordPress, Joomla, and Drupal. Listed integrations include Basecamp, Slack, Teamwork PM, and Google Analytics. The REST-style developer API uses SSL JSON requests and OAuth 2.0. Teams can collaborate in real time, use version history, and export PDF, image, or Slickplan XML files. The free version allows one sitemap and one user, with basic functionality, limited support, and web-link-only sharing. Paid plans start at $10.79 a month billed annually, and a 14-day trial is listed.
