Blink is an offline light signaling app for sending SOS, preset phrases, and Morse-style flash patterns with your iPhone flashlight or screen. When you have no network, need a quiet way to get someone’s attention, or want a simple visual signal within sight range, Blink helps you send short, clear messages fast. It is designed for camping, hiking, night meetups, trail coordination, car-to-car reminders, and other short-range communication scenarios where sound or connectivity may not work well. You do not need to know Morse code before using Blink. Choose SOS, a preset phrase, or enter a short custom message, and the app converts it into a readable flash rhythm. Chinese text can be converted to pinyin before Morse encoding, and you can preview the rhythm before sending.

It does not contact emergency services, rescue agencies, or personal contacts. In a real emergency, use local emergency numbers, satellite SOS, a whistle, signal mirror, radio, or other more reliable rescue methods when available. Whether a light signal can be seen or understood depends on distance, obstacles, weather, ambient light, battery level, device brightness, receiver attention, and whether both sides understand the intended meaning. Do not rely on Blink as your only emergency option.
