Parents are being alerted by schools to a new smartphone app, Sarahah, which has become popular in Ireland, overtaking Twitter and Tinder on Irish app charts. The App has 20 million users worldwide.

The App was originally designed to provide constructive anonymous feedback in workplace environments but appears now to be primarily be used by teenagers. Schools are concerned that the App is being used by some children to bully others.

Users can link the App to their Facebook and then share an image from their Facebook page seeking feedback on the image through the App. As the responses are anonymous, many of the responses can be very nasty.

There are also reports that the App gathers all contact information from a user’s phone and uploads it to its own servers.

Some schools are banning the Sarahah App and asking parents to delete it from their children’s phones
