Introducing Rheo
Growing a mobile app comes down to distribution and funnel optimization. Rheo unblocks the second — design, ship, and improve in-app flows without waiting on App Store reviews.
Meet Rheo — the mobile experimentation platform for designing, shipping, and improving in-app flows without waiting on App Store reviews.
Two verticals, one bottleneck
Growing a mobile app really comes down to two things.
Distribution — getting users in the door. Ads, ASO, influencers, partnerships. This is where most teams spend their budget and attention.
Funnel optimization — what happens after they install. Onboarding, paywalls, win-backs, upsells. This is where conversion and revenue actually compound.
The problem is that funnel optimization moves at the speed of App Store review. Every copy tweak, new screen, or branch you want to test waits on a release cycle. Days turn into weeks. Experiments stall. Small lifts never ship. Revenue stays flat while distribution keeps pouring users into a funnel you can't iterate on fast enough.
Rheo is built to fix that.
Ship your funnel over the air
Once the Rheo SDK is integrated, your team owns the journey from the dashboard. Design screens on the canvas, configure branches and targeting, hit publish — and the SDK in your app picks up the latest version immediately.
No App Store submission for screen changes, copy, structure, or experiments. Ship today, learn today. Product and growth teams iterate on the funnel while engineering handles the one-time SDK setup.
Build any journey on the canvas
Onboarding is just the start. Teams use Rheo for win-back flows, feedback collection, cancellation surveys, stories-style experiences — any multi-step journey that used to require an app release to change.
Every screen is a node on the visual canvas. Zoom, pan, and drag to reorder. Branch on single choice, multiple choice, or open-ended text. Handle system moments like ATT prompts, location, and notifications — and react to whether permission was granted or denied. Decision nodes let you route users by traits, attributes, or live conditions.
Preview the entire flow in the editor simulator before you publish. Tap through branches, test edge cases, jump to any screen — seconds, not a release cycle.
Everything renders as native UI on iOS and Android, not a WebView dropped on top of your app.
Learn what converts, ship what wins
A flow platform isn't useful without data. Rheo shows you exactly where users drop off, step by step — completion, conversion, and revenue tied to each screen in the journey.
Run holdouts and variants on copy, structure, and timing. Read lift on trial starts, purchases, and MRR without shipping an app update for every hypothesis. Small lifts on onboarding or paywall completion compound into real revenue.
Rheo works with the stack you already use — RevenueCat for subscriptions, your MMP for attribution — not instead of them.
