Heads Up turns your rear-facing camera into a passive collision sensor. Walk, scroll, text, or navigate — if something is approaching on a path toward you, your phone vibrates before you see it.

How it works
Heads Up runs silently in the background. The rear camera feeds a continuous on-device detection pipeline that tracks approaching objects and estimates their trajectory. When something enters a collision path, a directional vibration pattern fires — left, right, or head-on — giving you a chance to react without looking up.

No internet connection required. No data leaves your device. Detection and alerting happen entirely on-device.

Activates automatically
A built-in step detector gates the camera: Heads Up wakes when you start walking and goes dormant when you stop. Battery and camera are not used while you are standing still.

Directional alerts
Vibration patterns distinguish the direction of the threat — left approach, right approach, or direct head-on — so your instinct can respond before your eyes do.

Designed to stay out of the way
The alert overlay is fully transparent. Alerts fire without interrupting whatever you are doing on screen. There is nothing to tap through.

THIS IS A SAFETY AID — NOT A SAFETY GUARANTEE

Heads Up is an assistive tool only. It will miss objects. It will misfire. Camera angle, lighting, occlusion, object speed, and countless real-world variables all affect detection. This app is not a substitute for paying attention to your surroundings and must never be relied upon to prevent injury or harm.

You use this app entirely at your own risk. The developer accepts no responsibility or liability for any injury, accident, loss, or damage arising from use of or reliance on this app.
