Google publicized their GMail Tap app on April 1st. It was widely reported as an April Fools day joke. The GMail Tap app that allows people to enter email using only a 2 key keyboard... which just happened to be buttons for the Morse Code dot and dash.
However the HotPaw Productions Morse2Text iPhone app has been in Apple's iOS App store for over a year. It allows both straight keying and an Iambic keyer mode with one button for dots and one for dashes, where it then converts the Morse Code into text which can be sent directly to Mail.
And Morse2Text has actual blind customers who find it useful. No joke at all.
