We can easily determine the total number of edits made via either the iOS or the Android app by using the public `mobile app edit` tag (example: [[https://en.wikipedia.org/wiki/Special:Tags | English Wikipedia]]), which already indicates that the vast majority of edits from the Android app still comes from non-description edits (cf. T184096#4164186 ). However, this does not give us the numbers for Android (or iOS) separately.
To that end, we should have separate edit tags for the Android and iOS apps going forward. First step would probably be to look at the code that currently creates the `mobile app edit` and see if it can be modified to include `ios app edit`/`android app edit` in addition to `mobile add edit`. (See [[ https://www.mediawiki.org/wiki/Manual:Tags | mw:Manual:Tags ]].)
It appears natural to calculate this number by project (wiki) first, followed by segments once the segmentation endeavor has something.
