Personal safety app bSafe is competing with Angry Birds and Facebook as one of the most downloaded iPhone apps in Norway, ahead of its launch in the US and the rest of the world. The free app allows users to select personal guardians who will be notified if there is an emergency with an SOS message that includes the sender’s location. bSafe has also been well received on Android, according to its maker Bipper, and will soon appear on BlackBerry devices.
