Looks like we've experienced some kind of problem on the Windows Phone app count line shown in the above graph measuring the amount of newly added apps. It's shown to be pretty much halted. But fear not dear chaps, I've brought along some crumpets, cups of tea and some Pimms (you just never know) to keep you all patient while we work through some possible explanations.
So we've seen a sudden halt in growth, what's the cause? Well, we must not forget that "Mango" is just around the corner and developers have been using the beta tools provided by Microsoft to update their apps by taking advantage of new APIs etc. with any new projects they're undertaking. It could well be that all apps being developed now are actually taking advantage of the features (and improvements) found in "Mango" and will be submitted once the doors open up to developers.
Then again Mark, who tipped us on this news, also made a point about developers potentially having issues with the newly updated AppHub, which is backed by some reports. The platform has previously experienced a slow down in app growth back in January, as shown in the chart above and below. This certainly isn't anything to get worked up about, I'm sure we'll experience a flood of new submissions once "Mango" submissions are opened and the update is rolled out to the public.
In the end (or if you wish to have the tl;dr version of this article) - "Mango" is coming and developers may be waiting for the submission gates to open up. Nothing to worry about, quality over quantity right?
