Localizing its upsell paywalls lifted upsell screen conversion by 50% for Photoroom, an AI photo editing app. Photoroom ran the tests using Superwall, and the result was published as a RevenueCat customer story.

## Result

**+50% upsell screen conversion**

- Upsell screen conversion rose 50%.
- The number of variants and rounds behind the figure was not stated.
- Which languages or markets were included was not shared, nor whether prices also changed.

## Control

Upsell screens were not localized for each market.

## Variant

Upsell paywalls were localized for users' markets, then tested and refined over several rounds.

## Why it likely won (our reading)

- Users trust and understand a paywall more in their own language.
- Local wording can make benefits feel relevant instead of translated.
- The figure reflects several iterations, so part of the lift may come from later design tweaks.

## Caveats

The story describes testing and iterating, so the 50% may be the result of several rounds rather than one clean split test. It was published by RevenueCat, which integrates with Superwall, and sample size and duration were not shared.

## How to run this test

- Hypothesis: If we localize the upsell paywall copy for each major market, then more users will upgrade because the offer is clearer and feels made for them.
- Primary metric: Upsell screen conversion by market
- Guardrail: Refund rate by market
- Guardrail: Trial-to-paid
- Guardrail: Proceeds per user
- Who should test it: Apps with a large share of users outside their home language market. It matters less if nearly all users read the app's main language.
