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

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

Version 1.36.1 · 2026-09-15
Bug Fixes New Features Artifact Upgrades up to Level 24, Artifacts can now be upgraded beyond their previous limits, granting additional stats. Higher upgrade levels require Mithril, a new resource. New Guild Boss: Prime Mechanicus, A new daily Guild Boss that refreshes every 24 hours. It uses separate attack attempts, rewards Mithril, and can be challenged alongside the existing Guild Boss using decks already used against other bosses. Expanded Guild Boss System, Two Guild Bosses are now available to challenge each day.

This list is cut off. Apple shows at most 10 in-app purchases, and this app is at the limit — so it very likely sells more than we can see.

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.
