In v6.2, we added some wikitext editing tools to the iOS app (T209168). We also verified that the [MobileWikiAppEdit schema](https://meta.wikimedia.org/wiki/Schema:MobileWikiAppEdit) is tracking the basic user editing behaviors correctly (T215329).
The purpose of this task is to use data from [MobileWikiAppEdit](https://meta.wikimedia.org/wiki/Schema:MobileWikiAppEdit) and Mediawiki databases to measure the impact of these new editing tools. Specifically, we're going to look into:
**Annual plan metrics**:
- Number of edits
- Edits/editor
- Revert rate
- User retention rate
**Other user behavior questions similar to T203723**:
- The count of edits by languages, devices (iPhone vs iPad), log in status (anonymous or not)
- User funnel: How many/what percent of users start the description editing process? How many/what percent of them make it to the point of saving the edit?
@JMinor and @cmadeo , please let me know if there is anything else you want to know, and what was the intended impact (i.e. what do you expect to see, and expect not to see).
Given that the release date is Feb 21 2019, we want to have at least 30 days data for this task.
