The old apps have been in the wild for ages but they had no editing ability. The new apps have editing but aren't in the wild yet - they are only being alpha tested by about 100 users at best at the moment. Wider availability this coming month. Since this is the first time apps will have editing I wanted to get both CU and UA for analytics right.

Thanks James.

No UA data is recorded from any platform for non-edit actions like pageviews and watchlisting, even if an editor is logged in, right?

Subject: Re: [WikimediaMobile] Mobile and CheckUser (Was [mobile-l] Wikipedia App User Agents)

The mobile apps are definitely in the wild, my understanding (from some checks in the past and from the discussion in the other thread) was that it was just the 'normal' useragent for the phone with the addition of a WikipediaMobile identifier at the front (so that you could tell it was from the app). They aren't very common but I have seen some which I knew were app driven.

The reason this came up was that one of the discussions that came up in that other thread was to rewrite the user agent to be less unique which would make it harder for CUs to tell users apart (especially once they found out, which they often do and these discussions are on public lists). The compromise that Yuvi proposed was to send a 'special' user agent for checkuser so that it didn't lose the fingerprinting ability as much.

I got the impression from this discussion that the mobile apps aren't currently in use so the CUs have had no experience working with them. It sounds like I was mistaken.

Toby, what UA data do CUs currently see from edits made through the mobile apps?

CUs, is the information that you're currently getting from edits from the new mobile apps a good balance the concerns raised previously in this discussion?
