From what I've heard, the app's actually helped a lot more women escape Saudi Arabia because they can travel with less paperwork (if any) and not a lot of people secure their phones as they should, so women can discreetly abscond with their male guardian's phone, allow them travel, thus affording them more opportunities to leave that festering ass-wound of a country. Without it, there'd be an enormous amount of onerous paperwork that'd afford far fewer women to leave Saudi Arabia for literally and metaphorically greener pastures.
