Campus safety
From the library to halls, you are not walking alone.
Late study sessions, shift work, the walk across a dark campus. Holler is built for the routes students actually take after dark.
Why students use Holler
Designed for the realities of campus life, not a corporate security pitch.

One shake, hands-free

How it works on campus
- 01
Add a flatmate or parent
Choose one trusted contact who gets your live location if you raise an alarm.
- 02
Walk back armed if you want
Start a session for the walk to halls; it ends on a timer so it is not always running.
- 03
Trigger if you need to
Siren, strobe, recording and a live-location alert, with your local emergency number one tap away.
Student questions
How do I set it off walking back?
Shake your phone. Arm a walk-home session and a firm shake fires the alarm and shares your live location, even with the phone locked in your pocket. The on-screen button, Lock Screen widget and Action Button also work.
Can my parents be my contact if they have an Android?
Yes. Your trusted contact gets your alert and live location on any phone.
Is Holler watching me between classes?
No. It shares your location only during an active alert or a session you start, and sessions end on a timer.
