Apple and Google are facing criticism for hosting a Saudi Arabian smartphone app on their platforms which allows men to track women’s movements and “stop them leaving the country.”

According to Insider, the app, named Absher — which is available on Google’s Play Store and Apple’s App Store — is “a government web service which allows men to specify when and how women can cross Saudi borders, and to get close to real-time SMS updates when they travel.”

The SMS feature reportedly notifies men “when a woman uses her passport at a border crossing or airport check-in.”
