Hi all,

here is the weekly look at our most important readership metrics.

As laid out earlier, the main purpose is to raise awareness about how these
are developing, call out the impact of any unusual events in the preceding
week, and facilitate thinking about core metrics in general. We are still
iterating on the presentation (e.g. to better take seasonality into
account, in particular including year-over-year comparisons) and eventually
want to create dashboards for those which are not already available in that
form already. Feedback and discussion welcome.

The most interesting news this time is the effect of the iOS Wikipedia app
getting featured in the App Store, see below. For those who haven’t been
following the discussion on this list (Mobile-l), I’d also like to
highlight that Jon Katz has recently posted
<https://lists.wikimedia.org/pipermail/mobile-l/2015-October/009839.html>
(to quote his TLDR) “Directional data [that] suggests that the project-wide
drop we see in pageviews is, in part, caused by shorter sessions on mobile
web compared to desktop (and a migration from desktop to mobile web)”.

Now to the usual data. (All numbers below are averages for October 12-18,
2015 unless otherwise noted.)

Pageviews

Total: 528 million/day (+0.9% from the previous week)

Context (April 2015-October 2015):

See also the Vital Signs dashboard
<https://vital-signs.wmflabs.org/#projects=all/metrics=Pageviews>

Desktop: 57.3%

Mobile web: 41.5%

Apps: 1.2%


Global North ratio: 76.9% of total pageviews (previous week: 77.0%)

Context (April 2015-October 2015):

Unique app users

Android: 1.16 million /day  (+-0.0% from the previous week)

Context (January 2015-October 2015):

Not much news here.

iOS: 280k / day (+0.9% from the previous week)

Context (January 2015-September 2015):

The overall DAU number don’t yet show a noticeable impact of the app
getting featured (see below), we’ll see.
New app installations

Android: 37.9k/day (-4.0% from the previous week)

(Daily installs per device, from Google Play)

Context (July-October 2015):

The sustained rise in installs we’ve been seeing since around August 21
(see also the discussion in last week’s report about the possible
connection with the “Back to School” recommendation in the Play store) is
ebbing now, whereas the uninstall rate holds pretty much constant.

iOS: 6.69k/day (+48.0% from the previous week)

(download numbers from App Annie)

Context (July 24-Oct 21, 2015):

Last week, the Wikipedia app became featured on the iOS App Store homepage
(below the fold, as second item in a list called "Learn Your Facts"). The
effect on downloads is already clear - I’m including the last three days in
the above chart too; we’ll see how the impact on user numbers and pageviews
turns out. Josh from the IOS team is following this closely.
