RevenueCat
Mobile IAP subscription layer
Free tier + paidPayments & billingrevenuecat.com
What it is
Subscription infrastructure layered on top of Apple and Google in-app purchases, now extended to web billing through Stripe. It normalizes receipts, entitlements, trials and renewals across platforms and adds paywall and analytics tooling. Free under $2,500 monthly tracked revenue, then 1% of tracked revenue.
Why it earns a slot
In-app purchase receipt validation is miserable to build and worse to maintain; RevenueCat reduces cross-platform subscriptions to a single entitlement check and stays free until you have real income.
Know before you commit
The 1% is charged on revenue before Apple and Google take their 15-30% cut, so the effective bite is larger than it appears. It is not a payment processor — on mobile the app stores remain merchant of record.
