FAQ
Why does the app need audio permission?
Morzen plays Morse code signals through the speaker. No audio is recorded — the permission is only used for playback.
Can I adjust the signal speed?
Yes. Go to Settings → Signal and use the WPM slider. You can also adjust the tone frequency there.
What is the Koch method?
The Koch method starts with just 2 characters and gradually adds new ones as your accuracy improves. It is the fastest scientifically proven method to reach real Morse code fluency.
Does Morzen work offline?
Yes. Morzen works completely offline. No internet connection is required.
