The pain

You built the app.The hard part should be over.

You spent weeks vibe-coding your iOS app. It works. People actually use it.

Now you want to charge for it — and suddenly you're 47 tabs deep in App Store Connect, drowning in StoreKit docs, and asking Claude what an “entitlement” is for the fifth time.

We've been there. So we built Tappa.

Ask Claude

You

what is an entitlement exactly

Claude

An entitlement represents a user's right to access a product or feature. In StoreKit, you verify…

You

ok but app store connect says invalid product id

Claude

The product ID must use reverse-DNS format and exactly match what you've set in App Store Connect…

Case studies

Built by makerswho've been there.

Tappa is built by indie iOS developers who've shipped real apps. We hit every wall you're about to hit. We built this so you don't have to.

Three apps · three problems · one fix

Case study 01

Lunara

Wellness · iOS · AI dream journal

4.71.4k reviews

The challenge

Lunara was running raw StoreKit and tracking conversions in Mixpanel. Every paywall A/B test required a new App Store review — three hypotheses a month, maybe one shipped. Funnel data lived in three places and nobody could agree on the trial-to-paid number.

What Tappa changed

Migrated to the Tappa SDK in one afternoon. Started using remote paywall templates and the plain-English dashboard instead of scrolling Mixpanel funnels. Pricing, copy and layout changes go live in seconds — no re-submission.

The result

+21%Trial → paid

14×Paywall iterations / mo

8h → 30mAnalytics time / week

We stopped arguing about which dashboard was right. We just looked at Tappa.

Questionsyou probably have.

You’re not paying for infrastructure. You’re paying for the part where someone explains what’s happening. We translate metrics into English. We answer support emails. We test our SDK against AI-generated code so it doesn’t break. If you’d rather figure it out yourself, RevenueCat is great. If you’d rather ship and learn as you go, that’s why we exist.
