Two runaway Saudi sisters on Wednesday urged Apple and Google to pull an "inhuman" app allowing men to monitor and control female relatives' travel as it helped trap girls in abusive families.

Maha and Wafa al-Subaie, who are seeking asylum in Georgia after fleeing their family, said Absher - a government e-services app - was bad for women as it supported Saudi Arabia's strict male guardian system.

"It gives men control over women," said Wafa, 25. "They have to remove it," she added, referring to Google and Apple.

Absher, which is available in the Saudi version of Google and Apple online stores, allows men to update or withdraw permissions for female relatives to travel abroad and to get SMS updates if their passports are used, according to researchers.
