AudraLa app de seguridad personal que funciona con la pantalla bloqueada

Existing safety apps fail at the moment they matter most — they require a screen tap, a passcode, a moment of calm. Audra was built for the opposite: phone in a pocket, one hand free, under stress. Every feature had to work silently in the background with the screen locked. Apple's background execution budget is narrow; a data race in an audio session kills the alarm silently. Getting Apple's Critical Alerts entitlement — which bypasses Do Not Disturb on responder devices — required a manual approval process with strict criteria.
