Need to ride your bike home but forgot your light? Use the Signals app on your iPhone to help signal to others while you ride your bike.

Portable and visible safety signal for biking, walking, running, and jogging.

Control the frequency of your signal and signal on your iPhone from your Apple Watch if available!

The rear (red) signal changes brightness based on your acceleration. This both helps others know you are changing speed and increases your battery life due to automatically dimming.

This app uses the accelerometer and does not use your location increasing your battery life.

Signals has several options:
*Red & White signals
*Left-hand signals
*Right-hand signals

If you have an Apple Watch, you can pair your watch to your phone to control signals with your watch while riding.

*Note: This app may cause epilepsy.

Love this app!

The only “fix” I’d make is to reduce the touch field when in red blinking mode. It’s really sensitive and flips back to a disclaimer screen too easy. Otherwise I’m crazy happy with the app. Thank you!

No more worrying when I'm riding my bike!
