Android

The latest update introduced a full interface redesign and new flashcard features. Early feedback shows a 0.35 point decline in the average rating on Android, though the sample size of two reviews is insufficient to confirm a trend. The net impact remains neutral pending further data collection.

UX
no evidence
The interface redesign lacks sufficient user feedback to determine if the changes improved navigation or usability.

Marlvel takeaways

Review ad delivery logic to ensure advertisements do not trigger during offline sessions, as users report this behavior persists post-update.
Monitor the rating delta as the post-update sample size increases to determine if the 0.35 point decline stabilizes or reverses.
Evaluate the impact of the interface redesign on user retention once the feedback volume reaches statistical significance.
