Wikimedia Apps/Team/Wikipedia Year in Review/Updates

October 2025

The Android and iOS teams continued development on the core flow of Year in Review. We plan to release the feature to users in early December.
Thanks to a partnership with Data Platform Engineering, we updated the “Total edits” figure to be global edits across projects for 2025. That way, edits from all projects can be reflected in the Year in Review, and we are not limited to the user’s first 500 edits. Last year we were limited to pulling the first 500 edits for the user’s primary language Wikipedia.
We formulated A/B tests to run within each app along with the release of Year in Review, so that we can learn how to improve retention of app users.
- On Android, we will be running an A/B test offering an extra benefit to Year in Review readers — a customized reading list based on their top articles. Learn more at Year in Review Reading List Experiment. The A/B test of the reading list is coordinated on this sub-epic: T404267.
- On iOS, we will be running an A/B test that allows some logged-out users to view personalization without logging in. Learn more at Personalization for logged-out users experiment.
We completed usability testing with the iOS version of the feature.
- Learnings:
  - Overall there are positive indicators that the personalized elements will enhance the experience for logged-in users. Logged-in users were more satisfied with personalized slides than logged-out users that saw collective slides.
  - The reading patterns, top articles, top categories, and geo slides were of particular interest to users. These were new slides added after our learnings from last year’s release of Year in Review.
  - People would like to see more dynamism with the slides and increased customization, particularly as it relates to the final highlights slide.
- Next steps:
  - We will make some improvements based on user testing before the December release.
  - More time-intensive requests will have to wait until next year due to the time-sensitive nature of the feature.

September 2025

We completed several spikes on iOS to investigate what would be possible to add in the 2025 version
- Explore offering users an ability to see which geography they read about the most. T401450
- Investigate custom app icons. T401842
- Investigate sharing the entire review. T402411
Usability testing with the updated iOS feature is underway, with both logged-in and logged-out users in English and Japanese. We’ll incorporate learnings and improvements from testing into the 2025 edition.
