Common questions

How do I type Morse into the translator?
Use dots and dashes with a space between letters and a slash (/) between words, for example ... --- ... / ... The app switches direction by itself. The row of keys under the box adds dots, dashes and gaps for you. It also accepts · and − and the other look-alikes people paste.

What is free and what is Pro?
Free: the translator with sound, the reference chart, the tap key with live decoding, and the first 10 Koch lessons at 10 to 25 WPM. Morse Code Pro adds the full course (all 41 characters), every speed from 5 to 40 WPM, flashlight and vibration playback, sending drills and stats. Pro is a one-time Lifetime purchase or a yearly subscription.

How do I restore or cancel Pro?
On a new phone, tap Restore purchases on the Pro screen or in Settings, signed in to the same App Store or Google Play account. To cancel the yearly plan, open your subscriptions in the App Store or Google Play account settings at least 24 hours before it renews. Refunds are handled by the store you bought from.

There's no sound.
Check that Sound is on under "Play as" and that your volume is up. The sound plays even when an iPhone is set to silent.

The flashlight doesn't flash.
Flashlight playback is part of Pro. Turn on Flashlight under "Play as". The first time, the app asks for camera access: phones switch the light through the camera. Nothing is filmed or saved. If you said no, allow it in your phone's Settings under Morse Code. Some phones can't switch the light quickly at high speeds; try a lower speed in Settings.

Why doesn't my iPhone vibrate?
iPhones don't use the vibration motor in Low Power Mode, while the camera is on (so not together with the flashlight), or when System Haptics is off in Settings > Sounds & Haptics.

The tap key reads my dots as dashes.
Lower the speed on the Key screen to match how fast you tap, or turn on "Follow my rhythm" so it learns your timing. Pause a little longer between letters, and about twice as long between words, or tap Space.

What is the Koch method?
You hear every character at full speed from day one and start with just two (K and M). When you get 90% of your last 20 answers right, the next character is added. Learning the sound of each letter, not counting dots, is what makes copying Morse fast later. Ten-question rounds a few times a day work best.

What do character speed and overall speed mean?
Characters play at the character speed (in words per minute). A lower overall speed stretches the gaps between characters and words, so you have time to think while each letter still sounds right. This is called Farnsworth timing.

How do I start the lessons over?
Settings > Start lessons over. Your progress is kept only on your phone, so deleting the app also deletes it.
