App store ranking definitely will affect a lot for app development, currently, it seems that Apple started to promote their own apps at the top charts section. Apps like Numbers, Keynote, Pages, iMovie and iTunes U, in higher positions than they would normally rank. When viewed on an iPhone, these apps are showing up intermingled in the Top 20 Free applications on the iPhone. We will updated more details for you here.

This situation may be related to a bug in Apple’s App Store ranking algorithm, but it’s a persistent one if that’s the case.

It doesn’t appear to be impacting the relative rankings of most other Top applications besides Apple’s. That is, Facebook Messenger is still at the top of the App Store, followed by newcomer Acapella from PicPlayPost, then YouTube and then Facebook.

However, in the desktop version of the store, a game called Twist is ranked higher than Instagram and Snapchat, while on the iPhone 6s version of the App Store, Twist shows up immediately after those two applications, even when the two charts were viewed at the same time.

Also interesting is the fact that Top Free Charts listings seem to vary from device to device. For example, with another TechCrunch writer, I compared the rankings from an iPhone 5s and an iPhone 6s, both running the latest version of iOS, at the exact same time and found we had two different versions of the App Store’s Top Free Charts on our respective phones.

Some app store optimization company has already started to investigate the happened things. According to its initial findings, Apple’s apps seem to show up in random positions on the App Store app on the iPhone, and would sometimes remain listed in the Top Charts even after they were installed on the end user’s device. The company was alerted to this behavior when it noticed that its own ranking data wasn’t matching up with what was appearing in the App Store itself.
