Light Signals is intended for fast signaling via the phone’s flashlight, phone screen, or watch screen.

The application is available in two form factors, each of which can work independently: for phones and tablets, and for Wear OS smartwatches.

The signals can be emitted via the device's screen continuously or in a blinking mode with a wide variety of colors, as well as by blinking the device'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 is also useful for people with poor eyesight or whenever an audible signal is needed.

The main screen of the app has instant access buttons for sending a SOS signal, separate buttons for red and green signals, and a button to control the flashlight. The signal’s frequency, color, and sound can be changed on the spot without interrupting the app's operation. Another convenient feature is the background mode, which allows you to start the app directly from the notification bar, lock screen, or during startup.

The app features 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.

Light Signals can be a survival tool and is mainly intended to be used anytime a warning signal needs to be sent, especially at night or in low-visibility conditions like fog, smog, rain, or snow:
• for pedestrians, especially when crossing unlit streets and roads or when walking along a road at night;
• for bikers, scooter users, rollerbladers, etc., as warning signals (for example, by placing your phone in the mesh pocket of your backpack or courier bag);
• for drivers during tasks like changing a car tire 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 tracks;
• for school group instructors when the group is crossing the street or walking along a road;
• for signaling on boats, yachts, etc.;
• for signaling during outdoor activities or tourism;
• for signaling during critical situations when a visible or audible SOS signal may be needed.

Other possible app uses:
• Using your phone screen as a light source can often be more comfortable than using an overly bright flashlight, for example during repair work, reading, as a night light, or as lighting inside a tent;
• Various color lighting for photography;
• For educational purposes, such as learning traffic light signals, marine light signals, railway light signals, or other types of signals;
• As a light box;
• Testing your screen for cracks or dead pixels;
• Controlling your device’s flashlight.
