ASO guide

A/B test app screenshot messaging.

Change one variable at a time: headline, proof overlay, background treatment, or screenshot order.

Reference table

Variant	Change	Keep fixed
Promise	Headline and subtitle	Screenshots, device, background
Proof	Stars vs quote	Main headline and UI capture
Visual style	Preset/background	Copy and app UI

A render spec makes ASO variants reproducible. You can review the exact diff instead of eyeballing editor changes.
