Twitter has launched the official Android app for Fabric, the company's mobile development platform. The app allows you to monitor your app's analytics and diagnostics, viewing things like installation numbers, where your apps are installed, the number of currently active users, and much more.
Throughout the day, you'll get alerts when your apps are impacted by major issues. You can get a look at how many users are affected, as well as which platforms and specific devices have been hit with the issue. If you have multiple apps, you can control what notifications you receive on a per-app basis, so you won't be overwhelmed in case a problem affects more than one app.
You can grab Fabric from the Google Play Store right now.
