Apple and Google are being pressed to remove an app that lets men track their wives and daughters in Saudi Arabia. Available to download for free, Absher allows Saudi citizens and residents to access a host of services including getting a passport, a birth certificate or paying traffic violations.
The app also lets men in Saudi Arabia specify when and where to adult women under their "guardianship", including wives and unmarried daughters, are allowed to travel.
An SMS feature sends a message to the male guardian when their wives and unmarried daughters use their passport at a border crossing or the immigration counters at an airport.
This example is from Aljazeera News.
I'm a little confused why these men would let their wives and daughters have cell phones and passports in the first place If its all about control.
