BootyCall is a launcher application released for the OUYA platform that allows you to take customization of the unit to the next level. No longer are you stuck launching the OUYA Launcher/Menu when you power the device on or when you exit a game/application. Instead BootyCall allows you to choose your own custom application to fill these needs, from KODI/XBMC for a media centric interface to Nostalgia for the ultimate emulation machine, boot what ever you like.
On Screen Alerts allows you to receive notifications on your OUYA device from UDP capable devices, as well as Pushbullet. Some examples of this are notifications for incoming phone calls, sms messages, email, IFTTT notifications, and that is just the beginning.
