Cool work...I haven't downloaded the app to my phone yet, but is there a stage between activating the app and then going into emergency mode, e.g. broadcast + emailing all emergency contacts?
I could foresee situations in which someone is fearful, but not yet ready to raise the alarm...in which case, having the phone go into video/audio/geo-broadcast mode would be nice, but not "email/text everyone".
I really liked the accompanying blog post (https://medium.com/@marinosbern/witness-livestreaming-for-em...)...a lot of nice meditations on making something new by noticing the small inconveniences and barriers in real-world usage of existing solutions.
