Designed so that men are unaware of its existence, it is a way for women to alert trusted friends when they feel threatened. Awareness of the app was generated through the use of highly-targeted media, such as messages on bikini labels and waxing strips.
Some 245,000 women have downloaded the app, which has been activated more than 100,000 times.
