Key takeaways for Duck

Where is it heading?

Addressing the latest stability regressions is critical to preventing churn, as the current technical debt is actively undermining the brand's primary differentiator.

  • Graphical regressions in the latest update disrupt core browsing, which compounds the rating drag already visible on Android.
  • The app remains in a maintenance-only cadence, with no new feature expansion in the last three months.
