Blink vs Flashlight

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. Key Features SOS and preset signals • Send SOS and common emergency phrases quickly • 3-second countdown helps reduce accidental sends • Loop sending with clear stop controls • Live progress, current character, and rhythm display Two sending modes • Flashlight mode uses the rear LED for outdoor and night signaling • Screen mode uses full-screen light for close-range or quiet situations • Adjustable transmission speed for different distances and conditions Preset phrase library • Emergency, outdoor, medical, teamwork, silent communication, and direction phrases • Useful for common requests such as help, stay here, I am safe, need water, and more • Good for pre-arranged signals with friends, teammates, or family Custom messages and text signal tools • Turn short text into a Morse-style timing preview • Estimate transmission duration before sending • Large text, marquee, and flashing text modes for close-range silent cues Camera-assisted flash reading • Point your camera at a flashing light source to help read dot-dash rhythm • Useful for practice, testing, and nearby reception • Results depend on distance, alignment, brightness, motion, and ambient light Night mode and device protection • Red screen flash with reduced brightness for lower glare at night • Warnings or automatic fallback for heat and low battery situations • Pause protection during long repeated sending sessions • Auto-pause when the app goes to the background Blink Pro One-time purchase. No subscription. • Unlock all phrase categories • Save favorite phrases • Add custom phrases and longer custom messages • Customize screen flash colors • Access full history and quick resend • Use higher speed ranges • Adjust loop intervals Useful scenarios • Camping, hiking, and trail coordination • Night meetups and campsite signaling • Quiet, non-verbal reminders • Practice and testing for light-based signaling • Offline backup signaling when connectivity is unavailable Important safety note Blink is an auxiliary signaling tool. 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.

More than a flashlight. One app for everyday light, cycling and running visibility, a music-reactive party strobe, and your own custom flash pattern. FLASHLIGHT Instant torch access with a single tap. Adjustable brightness for everyday use. CYCLING A dedicated visibility mode for riding after dark. Choose from City, Dark Road, High Vis, or a fully custom preset. Use your screen as a Rear Light in Solid, Pulse, or Double styles, in Red, Amber, or White. Optional Brake Light uses motion detection to briefly flash red when you slow down suddenly. Note: this mode is a visibility aid, not a substitute for legally required bike lights, and it does not guarantee safety. WALKING A separate visibility mode for walking in low light, with Soft, Beacon, Attention, and Custom presets, plus adjustable screen color and brightness. RUNNING Two light modes for runs: a steady Normal Pulse, or Motion Reactive, which adjusts to your movement and pace. This is a visibility light, not a fitness tracker — there's no GPS, distance tracking, step counting, or heart-rate monitoring. EMERGENCY A bright, attention-grabbing visual SOS signal for extra visibility when it matters. Important: this is a visual signal only. It does not contact police, ambulance, rescue services, or any emergency contacts. PARTY A sound-reactive light mode. Your iPhone's microphone is analyzed in real time, on-device, so the light pulses with the bass and energy of the music around you. Choose Low, Medium, or High sensitivity, or set your own rhythm with Tap Tempo. CUSTOM PATTERN Build your own flash pattern by setting the exact on and off duration. Your pattern is saved locally on your device. PRIVACY Flashlight collects no user data. There's no advertising SDK, no tracking SDK, and no account required. Microphone analysis for the Party mode and motion detection for Cycling and Running happen entirely on your device — audio is never recorded, stored, or uploaded anywhere. A NOTE ON SAFETY Rapid flashing lights can affect people who are sensitive to light. Please use the strobe and flashing modes thoughtfully. As noted above, Emergency mode sends a visual signal only and does not contact emergency services.
