Facebook was the typical example of app we gave to illustrate that a popular app is not necessarily a good app. It was highly downloaded, ranked but poorly engineered and designed on standards that were not optimal for iOS (hmtl5). Our App score rating (quality rank for app) was very low: 32. Meaning Bad.

The app was slow, slow, slow. Users were always complaining about it. We officially asked Facebook to build a new app, before even getting to build a mobile phone.

But yesterday Facebook released a new app. It is highly appreciated. Our App score detected that, in a few hours. Many signals started to appear both in and outside the app store.

From 32 Facebook’ App score jumped to 94 [at mid day it was at 55], which is very high and probably well deserved. It’s fast(er) and attention to some details are nice (even the app icon was updated) for example the in app notification for new statuses, the new status update publishing section

The app could still be better: for example the picture upload feature requires still too many clicks

But overall, Facebook has done a good job! [and good job App score!]
