Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

Store update history

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

App Store

Version 8.2 · 2026-10-28
FIXED • Careers no longer lose fights if the app is closed or killed – the game now saves after every fight • Unlocking the full game on the create-fighter screen no longer dumps you into a nameless 25-year-old with no way to create a new fighter • Fighters could be booked against themselves, putting a phantom win and loss on their record. Fixed – existing saves are repaired automatically • Crowd noise kept running in the background after every watched fight, slowing the game down over long sessions. Fixed • Saving uses less memory, which should stop white screens while saving • Rivalries screen buttons work again • Save export files are much smaller, so phones can share them NEW • Boxing…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
