For UK mobile-app developers: iOS App Store and Google Play in-app purchase rules, server-to-server card payment for non-digital goods, web-purchase circumvention for digital goods (Spotify-style), embedded SDK payment (Uber-style).

FAQs
Can a UK mobile app use Stripe instead of Apple In-App Purchase?
Yes for non-digital goods. Apple App Store rules require In-App Purchase (and take 15-30%) only for digital content consumed within the app: subscriptions, premium features, virtual currency. Real-world goods and services (Uber rides, Deliveroo orders, Airbnb bookings, ASOS purchases) can use external payment (Stripe, Adyen) because they fall outside the IAP requirement. Google Play has similar rules.
How does a UK fitness or learning app handle the IAP cut?
Two paths. Path A: accept the Apple/Google 15-30% cut on in-app subscriptions in exchange for IAP convenience. Path B: redirect customers to web checkout (Stripe Checkout) for sign-up, then unlock the app via subscription token. Path B requires careful UX (Apple sometimes pushes back) but saves 13-28 percentage points on margin. Spotify, Netflix, Adobe all use Path B for new sign-ups.
What is the best UK in-app payment for non-digital goods?
Stripe Mobile SDK at 1.5% + 20p UK card-not-present is the default for delivery, marketplace, taxi, retail and other real-world apps in 2026. Adyen Mobile SDK wins enterprise above £1m monthly. GoCardless Mobile SDK wins for B2B apps with monthly Bacs subscriptions above £30/month.
How does SCA work for UK mobile-app payments?
SCA via 3D Secure 2 is delivered through the Stripe or Adyen SDK at first payment. Biometric authentication (Face ID, Touch ID, Android fingerprint) on the customer's device satisfies the SCA inherence requirement. Recurring charges qualify as Merchant Initiated Transactions and are exempt from challenge. Stripe and Adyen handle this automatically.
