An emergency SOS type app where you can add your friends to. I have autism and a panic disorder, sometimes I'm having extreme panic attacks, and sending out individual texts or calls becomes impossible. If there is an app where I can just press a button to notify all of my closest friends that I'm not doing well, and it sends my current GPS location, so that they can come over if they're near, that would be awesome. But it would also be an awesome app for use on festivals, if you lose your friends for instance. Or for going out clubbing and someone intimidates or threatens you. In short an emergency SOS app, that sends your current GPS location to your contacts, and lets you select a short caption before sending out the notification. A caption like "panic attack" or "epileptic seizure" or "mental breakdown" or "threatening situation" and so on and so on. Simple. Open app > select caption (or maybe you can pre-select a caption so you can skip that step) > send SOS. Thoughts? Does an app like this already exist?
