Users hate logging in twice when moving from web checkout to app. Tried deep links but they break if cookies clear. How are you maintaining session continuity between platforms? Bonus if it works with RevenueCat/Adapty without custom backend code.
Magic links via SMS/email.
After web purchase, users click a link that auto-logs them into the app.
No password needed.
We generate these through the subscription platform’s API.
Works with Adapty out of the box.
Used device fingerprinting (with consent).
When a user pays on web, we match browser fingerprint to their mobile device via SDK.
Auto-apply subscription without login.
Tricky but possible with platforms designed for web-to-app handoff.
Cut our support tickets by 60%.
We email an app deep link after checkout.
Not perfect, but most users figure it out.
Better than nothing.
Single sign-on via Google/Facebook. Easy.
