SOS Torch
A flashlight that also sends a real SOS in Morse code with one tap, plus a screen light and a strobe. Free on Android, no ads in your way, works instantly.
π¦ A torch that can shout for help
Every phone has a flashlight. Almost none of them can signal. One tap here sends the actual Morse distress pattern β three short, three long, three short β on a loop, which is visible far further than a voice carries.
What it does
- One-tap SOS in genuine Morse timing, repeating until you stop it.
- A plain torch that opens instantly, without a menu in the way.
- Full-screen light for when you need a soft area glow rather than a beam.
- Adjustable strobe for visibility at the roadside.
Who it is for
Drivers, walkers, campers, and anyone who would rather have it installed before the night it matters.
How to signal SOS, and why the timing matters
SOS is not three letters sent one after another. It goes out as a single unbroken group β three short, three long, three short β with no pause between the letters. That is what makes it unmistakable to someone who does not know Morse at all: they are not reading letters, they are seeing a pattern that nothing else produces.
Morse is built on one unit of time. A short flash lasts one unit, a long flash three. The gap between flashes inside a letter is one unit, and the gap between letters is three. SOS runs all nine flashes together on the short gap, then waits before repeating.
| What | Pattern |
|---|---|
| S | Β· Β· Β· |
| O | β β β |
| SOS, sent as one group | Β· Β· Β· β β β Β· Β· Β· |
A group of three, evenly spaced and repeated, is widely understood as a call for help on its own β three flashes, three whistle blasts, three shouts. If a light has no SOS mode at all, three slow flashes repeated every minute still reads as distress.
Two things worth knowing before you need them. Sweep the beam slowly across the horizon rather than holding it still, because movement is what catches an eye at distance. And a phone torch run flat is a phone that cannot make a call, so signal in bursts rather than leaving it running.
Questions people ask
What is the SOS Morse signal?
Three short flashes, three long, three short, repeated. It is the internationally recognised distress signal and it is understood without any shared language.
Does it drain the battery?
The LED uses real power, so a continuous SOS will run a battery down over time. The screen light and the strobe cost far less if you only need to be seen nearby.
Does it work without internet?
Yes. Nothing in the app needs a connection.
