How to read this
Apple's public feed only shows recent reviews, so this is a snapshot of the last weeks or months, not the app's full history. Popular apps attract complaints in proportion to their size; the useful part is which issues repeat. Generated 14 October 2026. We have no relationship with KAYAK.
