In preparation for this I pulled 2022 editing data for iOS app users from mediawiki_history using revison_tag = ios app edit. I expected to see edits on commonswiki, particularly because data on ios_notification_interaction shows the most frequent source of notifications is commonswiki, with the majority of those notification types are edit-user-talk (see chart).

Need to investigate, it seems most likely that iOS edits made on Commons are not being properly attributed to iOS users in the revison_tag field. The data I'm looking at is from 2022-04 and going back to 2021 edit data and shows no iOS edits on Commonswiki at all.

We are planning to look at correlation between notification engagement and editing activity post-notification engagement, will post findings here w/r/t iOS edit tracking on Commons.

How many users have opted to receive native push notifications?
We track device_level_enabled for users who interact with notifications (66.6% enabled) and all iOS users overall (3335, 5.1%) (from schema mobilewikiappiosuserhistory). There is a high count of notDetermined which I will be looking into.

What percent of our DAU have taken any action on the notifications screen?

The percent of notification users averages 0.4% of total iOS DAU.

Data

Will post here with results of editing/notification correlation data analysis when completed.

Post-notification implementation editing analysis:
Looking at editing activity post-notification shows a median +10.4% difference in edits made month over month, across 114 different language wikis. This smooths out with more data, using an average of edits by wiki for all of 2022 prior to Notification release, the median increase is +2.3% difference. We will need to look at next month's mediawiki_history editing data to see if this is an ongoing increase or a temporary lift.
Charts and Data

An additional analysis of notification impact on editing both on and off app as a result of notification activity would be in order as well when we have more data.

Added editing data for 2022-06 to analysis, the average monthly edits did decrease somewhat but we still see an overall increase in edits across 44.4% of wikis, with a median .74% positive difference (the average difference is 3.4%).
