Holler: Walk Home Safety Alarm

Holler turns your phone into a loud, flashing deterrent the instant you need it. One hard shake, or a tap, and your phone screams. A max-volume siren, a full-screen strobe, and a flashing flashlight turn a quiet street into a scene, the kind a threat wants no part of. Most safety apps call for help after something happens. Holler is built to help stop it before it does. WHY HOLLER Deterrence first. The alarm is designed to scare a threat off in the moment, not just record it afterward. Built to fire every single time. No login on the critical path. The siren sounds even over the silent switch, and the alarm still works with no signal. Your person, alerted. During a full alert, your trusted contact gets a message with your live location and a one-tap way to reach you. Private by design. Your location is shared only during an active alert. Never sold, never handed to advertisers. EU data residency. HOW IT WORKS 1. Trigger it. Shake hard, tap the SOS button, or use the Lock Screen or Action Button. 2. Your phone screams, flashes, and records. The deterrent fires and your back camera captures what is happening. 3. Your contact is alerted with your live location, and a one-tap emergency call button is always there. MORE WAYS TO FEEL SAFE Guard my walk. Arm Holler for the walk home and a hard shake works even with your screen locked. It turns itself off when your timer ends, to save battery. Get me home. Set a check-in. If you do not confirm you are safe in time, we remind you, then alert your trusted contact. Fake call. A realistic incoming call that gives you a reason to step away from a situation that feels off. Test SOS. Rehearse the full alarm safely, so you know it works before you ever need it. HOLLER PLUS Holler's alarm and trusted-contact alert are free.
