How chart movers work
Positions come from the App Store's top Reference charts for the US storefront, recorded daily. A top-100 reference position is far easier to read as competition than the overall chart, which is all household names. A slide can be a rival's launch, the end of a promotion or seasonality as easily as anything the developer changed.
