iPhone Screenshots


This is a very simple touchscreen-based Morse Code straight key. Practice sending Morse Code on your iPhone or iPod Touch.

Touch the display screen and the device will sound out a tone. The duration of the tone is controlled by how long you touch the device screen. Send Dots using quick touches, and Dashes by touches held down 3 times longer.

The tone frequency is adjustable from 300 Hz to 1200 Hz in the Settings. The volume can be adjusted to a lower level as well. There is also an iambic keyer (mode A) with adjustable dot speed available.

A Morse Code tutorial is not included. You can find one on Wikipedia or on the ARRL website.

Also see MorseTest, in the iPhone App Store, another educational Morse Code application by HotPaw Productions.

I like that this is a simple, straight key. Volume and pitch are adjustable via the settings. It was very hard to hear at first until I adjusted the pitch (currently at 845Hz). I've not tried it with the headset yet but I would bet I'd need to turn it all back down again since the Touch's speaker isn't all that great. This is what the developer says it is: a practice key. 73, KG4VPY

Honestly Works Pretty Well

I know the app seems like it won’t work and has little to no reviews, but it actually works pretty well. You can change the wpm (words per minute), the volume, and even the tone of the pitch. It is, in the end, just a button that beeps when you tap it/hold it down, which is great!
It also has Iambic Keyer mode too :D
For such an easy concept, this is the first app that I’ve found that actually works. Thanks!

Exactly what i wanted

This app is exactly what i wanted. All it is is just a key that beeps when you touch it. In this app, you can control the words per minute if your going to use it like a vibroplex, the frequency, and the volume. The down side is that using this like a bug isnt practical as your pressing on a flat screen but a strait key works perfect.
