Light Signals

Light Signals is intended for fast signaling via the phone/watch screen or the phone flashlight.

The application is available in two form factors: for phones and tablets, and for Wear OS smartwatches.

The app has easy and intuitive controls as well as quick access to all its functionalities. The settings can be changed on the fly and are very clear.

The signals can be made by the device's screen continuously or in a blinking mode with wide variety of colors as well as by blinking the phone's LED flashlight. The blinking frequency can be changed.
The signals can also be set to be accompanied by sound for better app navigation. This option also useful for people with poor eyesight or whenever an audible signal is needed

The app has two different color-coded instant access buttons for green and red colors and an option to send SOS via light and sound. Another convenience option is the background mode that allows you to start the app directly from the notification bar, lock screen or on start up.
Light Signals can be a tool for survival and is mainly intended to be used any time that a warning signal needs to be sent, especially at night or in low-visibility conditions like fog, smog, rain or snow:
- for drivers for instance during a change of the car's wheel on the road, especially if the car's battery is dead;
- for drivers to signal a traffic accident;
- for signaling to a train if your car is stuck on the train tracks;
- for bikers, scooter users, rollerbladers, etc. as warning signals (by, for example, putting your phone in a meshy pocket of your backpack or courier bag);
- for pedestrians, especially when crossing unlit streets and roads or when walking down a road at night;
- for school group instructors when the group is crossing the street or walking down a road;
- for signaling on boats, yachts, etc.;
- for signaling during any outdoor activity or tourism;
- for signaling during any critical situations when a visible or audible SOS signal may be needed.

Possible other app uses:
- using your phone screen as a source of light can often be more comfortable than using overly bright flashlight, for example during repair work, reading, as a night light, as lighting inside a tent, etc.;
- various color lighting for photography;
- for educational purposes, for example learning traffic light signals, marine light signals, railway light signals or other signals;
- light box;
- testing your screen for cracks or dead pixels;
- controlling your device’s flashlight.
