Rheo
Ship and test app funnels without App Store reviews
Growing a mobile app comes down to distribution and funnel optimization. Most teams nail the first and stall on the second, because every screen change waits on an App Store release. Rheo fixes that. Integrate the SDK once, then your team owns the journey from the dashboard: design funnels on a canvas, publish changes instantly, run experiments and measure what converts without waiting for an app store review cycles.
I built Rheo because I kept running into the same wall while growing mobile apps.
I'd pour time and money into distribution — getting lots of people to install my apps — without realizing my funnel had massive leaks. When I had a clear hypothesis for what to change, there was no quick way to test it. I was forced to wait: for a new app build, and for App Store review. Days turned into weeks, and iteration stalled.
The frustrating part wasn't a lack of ideas. It was that improving the journey moved at a completely different speed than acquiring users. I could tweak ad creative in an afternoon. I couldn't tweak the screen right after install without a full release cycle. Those small conversion lifts kept dying in the backlog.
I wished something like Rheo existed back then: integrate once, then own the in-app journey from a dashboard. Design flows on a canvas. Change copy, structure, and branches without a store submission. Publish over the air. Run experiments. See exactly where users drop off, step by step.
That's what I've built.
Rheo is for anyone who's felt that gap — when you're getting users in the door but can't iterate on what happens after install at the same pace you run growth experiments.
What Rheo can do:
- Visual flow builder: onboarding, paywalls, win-backs, feedback flows, and more - OTA publishing: no App Store review for flow changes - Analytics: step-level funnel analytics, drop-off analysis, cohort analysis - Experiments: A/B or multivariate testing - External Integrations: RevenueCat for paywalls and AppsFlyer for attribution - SDK support: React Native (live), SwiftUI (coming soon), Flutter (coming soon)
I'd genuinely love feedback from the PH community, especially from anyone building and growing mobile apps.
how does this actually play with apple’s strict review rules for remote functionality, do i risk getting flagged for changing ui flows without a release
This looks incredibly clean. My only hesitation with OTA flow builders is always Apple and Google stance on changing app behavior without a review. How does Rheo handle this under the hood to make sure we don't risk getting flagged?
This hits so close to home. The friction between marketing wanting to test a new onboarding hook and engineering having to squeeze an App Store release into the sprint is a constant battle. Absolutely love that you’re solving this, Stefano. Upvoted and sharing this with our mobile team today
Congrats on the launch, Stefano. Having RN support live out of the gate is huge for us. Quick question on the implementation side: how does this work with Expo EAS updates? If we're already using EAS Updates, does Rheo conflict with that at all, or does it run entirely on its own layer?
