Simulated Light-Signal Transfer
Type a word and watch Phone A transmit it using flashing light pulses, while Phone B decodes it in real-time.
Engineered for Silent Communication
Designed as a high-fidelity utility app, Flash Morse gives you full capability to communicate without cellular towers or internet data.

Real-time Camera Decoding
Uses your phone's camera stream to automatically analyze light fluctuations and decode flash pulses into characters instantly, completely offline.

High-power Flash Transmission
Pulse your device camera LED flash in precise Morse intervals. Broadcast text messages across visual distances clearly and reliably.

Voice-to-Morse Input
Dictate messages directly via speech recognition. Your words are instantly transcribed and ready to flash without typing, processed locally.

Speed Calibration Sliders
Adjust Morse signal speeds from 0.5x to 3.0x to calibrate and match ambient environments, visual distances, or receiver capabilities.

Built-in Morse Guide
Includes an offline dictionary cheat-sheet. Study codes, read signals, and master the Morse alphabet anywhere, anytime.

Offline & Secure Operation
Keep track of transmissions locally with 100% on-device processing. No cellular data, internet, or third-party servers required.

Shreyas Damase
Mobile & Android Developer
I am an Android developer passionate about building utilities that run entirely on-device. I believe that technology should be accessible, private, and capable of operating independently of large-scale cloud infrastructure.
Why I Created Flash Morse
Modern communication is built on complex infrastructure. We rely on cell towers, satellites, global fiber networks, and cloud databases just to send a simple text message. But what happens when you go off the grid, experience a power outage, or find yourself in an emergency where networks fail?
I realized the hardware already in our pockets is capable of bridging these gaps independently. Almost every smartphone is equipped with a high-intensity LED flashlight and a high-frequency camera sensor. By coding a system that bridges the physical space with light, we can turn any device into a self-sufficient transmitter and receiver.
“Flash Morse was born from a simple question: How do we communicate when the grid goes down?”
I built Flash Morse to turn this concept into an accessible, practical tool. The app requires zero internet access, zero account creation, and zero trackers. It is an open, private utility designed to translate, transmit, and decode line-of-sight light signals in real-time. Whether it's for emergency survival, education, or absolute communication privacy, I hope this tool serves as a reliable utility when you need it most.
