Vodafone wanted to demonstrate technology can be a powerful force for good. In Turkey one in three women face domestic abuse and they find it difficult to seek help. The Vodafone app allowed women to send a message to people they trust by shaking their phone and was promoted using discreet media channels which would not be seen by men.
254,000 women in Turkey downloaded the app - 24% of all smartphone users and has been activated 103,122 times.
