Google in a recent update for its Play Store , added a new feature allowing publishers to put their apps for pre-registration. The feature will not only be helpful for users, who’ll get notified when the app is actually released, but also for app developers, as it will help them gauge interest in their apps prior to release. There’s also an Unregister button in case you no longer want to receive alerts. Glu Mobile's Terminator Genisys: Revolution game (see image below) has become the first Play Store app to feature a Pre-register button.
