46 of the 50 top-grossing US casino apps have A/B tested their App Store page since August 2025, all of the top 10 included.

554 tests from 73 apps. Median: 8 days. A quarter added just one new screenshot.

One of them still showed Santa in August.

A model read 1,074,607 App Store reviews for me this month, the newest ones from 5,486 big iOS apps. The bill was $65.60.

195,188 of them mention the price or a paywall. All bug reports put together: 186,464.

Some numbers I didn't expect:

Two stories keep coming back.

Paid on a web page, nothing in iPhone Settings: "You can't cancel your subscription in the Apple account. And no one answers"
