Reference chart movers
Who gained and lost ground on Apple's Reference charts over the last 7 days (2026-08-24 → 2026-08-31). This is Apple's own genre chart, not the list above — a top-100 reference position is far easier to read as competition than the overall chart, which is all household names.

Positions come from Apple's public Reference RSS charts for the US storefront, snapshotted daily. A drop-off means an app left that genre's top 100, not the App Store. Movement describes what happened, not why — a slide can be a rival's launch, the end of a promotion or seasonality as easily as anything the developer changed. See movement across all categories.
