Glint has both sliders,
a sidetone and haptics.

Glint's settings: character and effective speed sliders, sidetone pitch, and Read a Signal

Character speed

How fast each letter is sent. Keep it at the speed you want to end up at, so the sound of every letter stays the same.

Effective speed

The overall pace once the stretched gaps are counted. Raise it as you get quicker at recognising letters.

Read a signal

Point the camera at a blinking light, or let Glint listen for a tone. It works out the sender's speed and reads the Morse back as text.

Hands-free

Copy with the screen off

Start a listening drill and put the phone in your pocket. Glint plays your weak letters at the speeds you set. The Lock Screen shows what is playing and lets you stop it.

Output

Speed presets for practice

Presets named Chill, Train and Fast change the pace without touching the sliders. Send through the flashlight or a screen pulse in the colour you pick. Prosigns such as SOS, AR and SK are supported.

Questions

What is Farnsworth timing?

Each character is sent at full speed, but the gaps between characters and words are stretched. You learn the real sound of every letter and still have time to recognise it. As you improve, the gaps shrink until the timing is standard.

How is Morse code speed measured?

In words per minute, using the word PARIS as the standard length.

Do I need Morse code for an amateur radio licence?

In most countries, no. The United States and the United Kingdom have both dropped the requirement. Operators learn CW because it gets through when voice does not, on little power.

What is a sidetone?

The tone you hear while sending, so you can monitor your own keying. Glint lets you turn it on and set its pitch.
