Appearance controls were launched with the 5.6.0 update. The theory was that making reading more customizable and comfortable we would encourage more reading, particularly longer reading sessions in the evening. That in turn would lead to more app re-use and retention (not for its own sake but as a measure).
Although we're limited in the available data, I'd like to understand if that theory proved true.
Specifically:
- Do users using 5.6.0 have longer or more frequent sessions compared to users of earlier version during the same period? More than recent historical averages?
- Was their any change in day 7 retention after this version or for new users downloading this version?
Bonus points:
- Has their been any change in the diurnal usage curve of the app? That is, do things like brightness and color control actually result in more pageviews or longer/more sessions in the evening and night hours?
- [Likely impossible, though maybe on Android?] Is there any relation between the appearance prefernces selected and the amount of use? That is do users of dark mode read more than people who leave the default settings in place?
