The BLINK App is for pedestrians walking or jogging by a road at night. By using the BLINK App the pedestrian's phone will become a beacon, allowing them to be seen from 5 times further away.

The flash and screen of the smartphone emit a flashing light on both sides of the phone, as a beacon in the dark. The sequence of light is not disturbing, nor drains the batteries more than any other normal application.

Be visible by wearing light-colored and reflective clothing. Drivers are often not expecting walkers to be out after dark, and you need to give them every chance to see you, even at street crossings that have crossing signals.

Also remember to just be as cautious at dawn or twilight, as drivers still have limited visibility or may even have the setting or rising sun directly in their eyes. Walk on the side of the road opposing traffic when there is no separate sidewalk. This way you will see the cars approaching you.

Didn't light up when I needed it to do it!

I tried using this app to help me when crossing some dim intersection on my walk from my office to my train, and I can't imagine a simple light strobing app performing any worse. It let out one or two little flashes and then would go dark for most of my time in the intersection. It's safer to turn on the flashlight and wave my hand in front of it to create a flashing effect.

Developer Response ,

Thanks for your feedback, unfortunately we couldn’t re-recrate your experience. However, it is important that your smartphone detects your movements, and that your BLINK App settings is set at the shortest time for the intervals. You can also read more about the settings at: http://knpo.org/blink/help
Important to note, that the BLINK App does not replace real reflexes but is a very good complement while jogging or cycling. Or as a solution when one has forgotten its reflexes.
Please feel free to contact us directly at info@knpo.org, att Richard, so we can assist you in more detail.
