Passback presents a web-to-app checkout system for iOS subscriptions, using a customer’s Stripe purchase to open the app with subscription status attached.

Landing page captured for the 2026-09-21 issue.
For
iOS subscription app teams testing web-to-app sales
Worth noticing
The proposed handoff uses a single-use token, while purchase-time records preserve the paywall and terms shown to each customer.

Field notes

The site breaks the proposed workflow into a funnel editor, Stripe connection, and token-based return to the app. It lists seven screen types, five starting templates, and a Swift integration described as four calls. Its accounting layer is unusually detailed: the homepage says it would retain the paywall, terms, preceding screens, reminders, cancellation visits, and app launches for later dispute review.
