FlwKit vs RevenueCat
RevenueCat manages your subscriptions. FlwKit optimizes the onboarding that gets users there.
RevenueCat is the industry standard for iOS subscription management. If you're building a subscription app, you're probably already using it — and for good reason. But RevenueCat starts at the paywall. FlwKit starts at the first screen. The onboarding experience that builds intent and gets users to your RevenueCat paywall is a completely separate problem. That's exactly what FlwKit is built to solve.
The core difference
RevenueCat is subscription infrastructure. It handles purchase logic, entitlements, receipts, webhooks, and revenue analytics. FlwKit is onboarding infrastructure. It handles the screens, flows, experiments, and funnel analytics that exist before any purchase decision is made. They operate in completely different layers of your app — and both layers matter. Most indie developers nail the RevenueCat integration and then hardcode their onboarding and never touch it again. FlwKit fixes that second part.

Pricing
RevenueCat's free plan covers up to $2,500 MTR — generous for early stage. Their paid plans start at 1% of MTR as you scale. FlwKit's Indie plan is $25/mo — unlimited flows, unlimited A/B tests, advanced funnel analytics. If you're already on RevenueCat, adding FlwKit at $25/mo to optimize the onboarding that feeds your paywall is one of the highest ROI decisions you can make. Better onboarding means more users reach your RevenueCat paywall. More users at the paywall means more revenue.
