“We got a 10 percent lift from the new screenshots. You put the old screenshots to 50, the new screenshots to 50, it runs until it gives you a high confidence rate and it tells you what percent better the new screenshots are as far as impressions to app downloads.”

App Store Screenshot A/B Test Delivered 10% Lift With Apple's Built-In Tool

None to Run used Apple's native A/B testing in App Store Connect to compare old developer-designed screenshots against a professionally redesigned set. The test ran until statistical confidence was reached and showed a clean 10% lift in impression-to-download rate. It's a reminder that App Store creative is a lever most indie developers leave untouched — and the test infrastructure to measure it is now free and built in.
