MyMiniFactory - 3D Print Filesv2.3.6

Released December 3, 2019Major

iOS

The recent major update resulted in a highly negative outcome, driven by critical technical failures that rendered the app non-functional on iOS. The iOS rating declined by 1.89 stars, dropping from a pre-update average of 3.17 to a post-update average of 1.28. Immediate hotfixes are required to address launch hangs and broken login authentication before user churn becomes permanent.

How it played out

Retrospective analysisAugust 1, 2026

The iOS rating declined by 1.89 stars since release, dropping from a pre-update average of 3.17 to a post-update average of 1.28. This severe decline is driven by critical technical failures, as users report the app hangs indefinitely on the loading screen and fails to process logins. Momentum is weakening as the unaddressed bugs leave the app entirely non-functional.

Marlvel takeaways

  • Prioritize hotfixing the launch crash where the app hangs indefinitely on the loading screen, which is the primary driver of the post-update rating decline to 1.28 stars.
  • Restore the broken login and registration authentication pathways to allow iOS users to bypass the entry screen.
  • Implement mandatory pre-release testing for iOS builds to prevent critical regressions from reaching the live environment when baseline sample sizes are low.
