Tips & tricks
Small things that make sending, decoding and learning Morse go a lot smoother.
Aim steady for light decoding
Rest the phone or brace your elbows; the camera reads a blinking light best when it’s not moving.
Find a quiet spot for audio decoding
Background noise competes with the tone — get closer to the source or reduce noise.
Keep an even rhythm on the tap key
It adapts to your speed, so give it a few consistent taps to lock on; very fast or uneven tapping can misread.
Torch runs a little slower on purpose
Phone flashlights can’t strobe as fast as a speaker beeps, so torch speed is capped to protect the hardware.
Learn with Farnsworth
Turn it on to hear characters at full speed with extra space between them — it builds the right instincts.
Start small in Practice
Two letters, then add one at a time (the Koch method). Chase streaks, not perfection.
Make it yours
Save your common phrases, and export “your name in Morse” as a wallpaper or an animated GIF to share.
Use SOS responsibly
It’s a great demo and a real skill — but it’s for fun and learning; don’t rely on the app as your only way to signal in an emergency.
