Translate your paywalls

Add languages and translate every screen in one view. Compare each translation with the original and see which strings still need work.

Publish without an app update

Set up named locations for paywalls in your app, such as onboarding or settings. Change the paywall assigned to a location from Voidhash. Published updates reach devices within about an hour.

Multi-screen flows

Build an onboarding flow with multiple screens. Open each step as a page, modal, sheet or dialog.

Custom components

Write your own components and add them to the designer alongside the built-in library.

Preview on your phone

Scan a QR code to try your paywall on a device before publishing. Works with iOS, Android and React Native.

Edit together

Work in the same design with your team or coding agent. See cursors, selections and edits as they happen.

Connect your paywall to purchases and analytics

Use your store products in the designer and track how each paywall converts.

Purchases

Display store prices and let users buy directly from your paywall.

Explore purchases
