The growth network for independent iOS apps

Your best growth channel is already in your app.

Recommend great apps to your users. In return, other independent apps introduce their users to yours. One thoughtful card turns existing attention into shared momentum.

A fairer growth loop

Great apps shouldn’t have to shout to get discovered.

Independent developers already have something ad platforms want: real attention from people who chose to be there. CrossPromo helps you exchange that attention with other quality apps—without turning your product into an ad feed.

How it works

From App Store link to a live growth loop.

CrossPromo does the network work. You choose where a recommendation belongs in your product.

  1. 01

    Register your app

    Share its public App Store link. CrossPromo checks the listing and creates your developer workspace.

  2. 02

    Place one native card

    Add the SDK to a natural moment such as a result, success, settings, or empty-state screen.

  3. 03

    Exchange real attention

    Every two verified recommendations your app shows earn one verified promotion of your own app.

  4. 04

    See what travels

    Follow verified impressions, clicks, CTR, placements, and the apps introducing users to you.

Designed to belong

A recommendation, not an interruption.

CrossPromo cards are small, responsive, and colored from each app’s own icon. They can sit inside the interface your users already understand.

  • ✓ Prefetched for a fast first appearance
  • ✓ Typed placements for safer integration
  • ✓ Native SwiftUI and UIKit support
  • ✓ Local preview components for design review

Small card. Compounding upside.

Built for the way independent apps actually grow.

Reciprocal by design

Show two verified recommendations and earn one promotion of your own app. Earned promotions stay yours until they are delivered.

Verified activity

Counted production activity comes from public App Store releases and is validated server-side—not trusted blindly from the client.

You control the fit

Review what appears around your brand with app and category filters, and choose placements that suit your interface.

A dashboard that closes the loop

See impressions received, cards served, clicks, CTR, daily trends, and the participating apps driving discovery.

Privacy, kept deliberately boring

Promote apps.
Not profiles.

CrossPromo measures participating apps, not people. It does not build a cross-app identity or store an installation ID, device ID, IP address, user agent, or locale.

What is CrossPromo?

CrossPromo is a reciprocal recommendation network for independent iOS apps. Participating apps display tasteful cards for one another, creating a shared discovery channel outside the usual paid acquisition platforms.

Which apps can join right now?

Version 1 accepts public iPhone and iPad apps from the Apple App Store. The production SDK supports native iOS, Flutter running on iOS, and React Native running on iOS, with an iOS 16 or later deployment target.

How does my app become eligible for promotion?

Register your public App Store listing, integrate the SDK, and release it through the public App Store. Every two verified ads your app shows earn one promotion; earned promotions never expire, even if you later stop displaying ads.

Will development or TestFlight impressions count?

No. Debug builds, simulators, StoreKit testing, TestFlight, and sandbox activity can help you test the integration, but they do not count as verified production activity.

What counts as an impression?

The SDK reports an impression after at least half of the card has been continuously visible for one second. Single-use server tokens and signed click redirects help protect the measurement.

Can I control what my app recommends?

Yes. The dashboard includes category and app-level filters. You also decide which sensible screens contain a card and can use the SDK’s ready-made component or build a custom presentation around its data.

Does CrossPromo track users across apps?

No. Events belong to participating apps, not people or devices. CrossPromo does not store an installation ID, device ID, IP address, user agent, locale, or App Transaction ID.

What do I need to change in App Store privacy?

Keep your existing answers, then add Product Interaction and Advertising Data under Usage Data for Third-Party Advertising and Analytics. For both, answer that the data is not linked to the user and is not used for tracking. The dashboard links to a click-by-click guide.
