Adapty offers three A/B test types, each suited for different testing scenarios:

• Regular A/B test: An A/B test created for a single paywall placement.
• Onboarding A/B test: An A/B test created for a single onboarding placement.
• Crossplacement A/B test: An A/B test created for multiple paywall placements in your app. Once the A/B test assigns a variant A/B test variants are alternative versions of the paywall or onboarding to test. , it shows that variant consistently across all selected sections of your app.

Each paywall/onboarding gets a weight that splits traffic during the test.

For instance, with weights of 70 % and 30 %, the first paywall is shown to roughly 700 of 1,000 users, the second to about 300. In Crossplacement tests, weights are set per variant, not per paywall.

This setup lets you compare different paywalls and make data-driven decisions for your app’s monetization strategy.

When to use each type

Each A/B test type is useful if:

• Regular and Onboarding A/B tests:
  • You have only one placement in your app.
  • You want to run your A/B test on only one placement and track economics changes for that placement only, even if your app has multiple placements.
  • You want to run an A/B test on old users (those who have seen at least one Adapty paywall).
• Crossplacement A/B test:
  • You want to synchronize variants across multiple placements. For example, you might change prices in the onboarding flow and in your app’s settings at the same time.
  • You want to evaluate your app’s overall economy. Running the test across all placements makes A/B test statistics easier to analyze than testing isolated placements.
  • You want to run an A/B test on new users only, i.e. the users who have never seen a single Adapty paywall.
  • You want to use multiple paywalls within a single variant:

Key differences

Feature	Regular A/B Test	Crossplacement A/B Test
What is being tested	One paywall/onboarding	Set of paywalls belonging to one variant
Variant consistency	Variant is determined separately for every placement	Same variant used across all paywall placements
Audience targeting	Defined per paywall/onboarding placement	Shared across all paywall placements
Analytics	You analyze one paywall/onboarding placement	You analyze the whole app on those placements that are a part of the test
Variant weight distribution	Per paywall/onboarding	Per set of paywalls
Users	For all users	Only new users (those who haven’t seen an Adapty paywall)
Adapty SDK version	Any for paywalls. For onboardings: v3.8.0+ (iOS, Android, React Native, Flutter), v3.14.0+ (Unity), v3.15.0+ (KMP, Capacitor)	3.5.0+
Best for	Testing independent changes in a single paywall/onboarding placement without considering the overall app economics	Evaluating overall monetization strategies app-wide

A/B test selection logic

Crossplacement A/B tests take priority over regular A/B tests. However, Crossplacement tests are only shown to new users — those who haven’t seen a single Adapty paywall yet (the getPaywall SDK method was never called for them). This ensures consistency in results across placements.

The following diagram shows the logic Adapty uses to select an A/B test for a placement:

On the A/B Tests page, regular, onboarding, and Crossplacement tests appear on separate tabs.

Crossplacement A/B test limitations

Crossplacement A/B tests cannot include onboarding placements.

Crossplacement A/B tests guarantee that each user sees the same variant across all placements in the test. This creates the following limitations:

• Only new users can participate. A new user is one who has not seen an Adapty paywall and whose app has never called getPaywall. Adapty cannot guarantee a consistent paywall chain for other users.

• The first placement the user encounters determines which paywall Adapty displays. You cannot change a user’s assignment or enroll the same user in more than one Crossplacement A/B test.

Crossplacement A/B test priority

• Crossplacement A/B tests always take priority over regular and onboarding A/B tests. If a new user qualifies for both a Crossplacement test and a regular test on the same placement, the Crossplacement test is shown.

• When multiple Crossplacement A/B tests with the same audience share the same placement, Adapty automatically assigns test priority based on the order they were added. The first test gets the highest priority. You cannot manually change it.

• Tests that target smaller segments of your audience automatically take priority over those targeting the All Users segment.
