Lubee SignalBy Lubee Labs
Lubee Signal is in development: a phone-based Morse tool for sending and receiving with the flashlight, screen, or speaker when catastrophic events take internet, Wi-Fi, and mobile service offline.
When catastrophic events take networks offline, someone nearby may still be within sight or hearing. Lubee Signal is being designed for Morse messages sent and received by light or sound, automatically or by hand.
Flashlight & screen — send short and long light pulses.
Speaker & listening — send tones or hear Morse nearby.
Automatic & manual — type, tap, listen, or enter Morse.
Dramatized imagined scenes—not real rescue accounts or tested outcomes.
···✦Under a fallen stairwell, Lina finds a narrow gap to the night sky. Her phone is cracked, but its flashlight still works. She sends three short flashes, pauses, then repeats. For a long moment, nothing answers. Then, far beyond the rubble, three lights blink back.
≈ ≈ ≈✦On a rooftop surrounded by rising water, Tomas spots a boat moving through the rain. The mobile network is gone. He angles his screen toward the street and taps a short pattern he practised in the app. The boat slows. A lamp flashes twice from its bow.
··· ——— ···⌁After an explosion, a family shelters behind a thick stone wall. Their phones cannot reach a network. From the other side of a blocked doorway, a faint tone repeats. One person recognizes the rhythm from a Morse lesson and answers with a careful knock.
··· ——— ···▱The phone has died, its screen black. But Noor remembers the pattern she practised: short, short, short; long, long, long; short, short, short. She taps it against a metal pipe and listens. This time, the message lives in the rhythm, not the phone.
These are fictional, dramatized scenes—not real rescue accounts or tested outcomes. In an emergency, follow trusted local guidance and contact emergency services when possible.
Screens from the app, in the order a visitor might explore them.
App screenshots arranged in a natural order: compose and send, receive and decode, then learn and practise. The captured interface is in English.
Tutorials and practice are designed to teach Morse letters, rhythm, and recognition—so the skill can stay with you when your phone battery runs out.
Signals can be blocked, missed, or misunderstood. Keep your phone charged, follow trusted instructions, and use emergency services where available.
