Background
In 2024-2025 the iOS team built a personalized Wikipedia Year in Review feature T371946. During development and after release, we identified several improvements to the App's local tracking that need to be made in early 2025 so that we have data for the version that releases on Android and iOS in December 2025. that can be made if we iterate on this project with a version for 2025.
3.2 Draft tracking hypothesis
If we introduce additional local storage infrastructure on both Android and iOS Apps by the end of Q4, we can be prepared to deliver 2 of the most popular user requests from the iOS Year in Review survey in December 2025.
Requirements
The 2025 version of Android and iOS Year in Review can leverage local storage to show personalized statistics on a user's:
- Articles read by Topic or ✅ Category (may be generated at end of year if needed)
- ✅ Top read articles, or most visited articles
- ✅ Total time spent reading on Wikipedia, Article with the most time spent reading
- ✅ Longest rabbit hole followed
- ✅ Articles read by geography (Places coordinates)
- ✅ In-app donations
- PM Updates FAQ Pages for information on what's tracked locally on device
- PM Add deployment dates so we can update the FAQ page later on with how much data is covered
