Type a message into your iPhone or iPod touch and wave it in the air.
Your message scrolls across the screen in large, bright type.
It really is as simple as that.
Well, OK, there are a couple more things worth mentioning.
Firstly, Wave It uses the full screen to display its scrolling message. Some similar apps use flashing letters or even a flashing row of dots to display theirs. There are advantages and disadvantages to the Wave It approach: The advantages are that Wave It is brighter, smoother and more legible than some others. The main disadvantage is that Wave It is not so suited to a very fast wave. For best results a moderate, steady wave from the elbow is recommended, as is some practice in front of a mirror.
Secondly, and *** PLEASE NOTE THIS *** Wave It can currently only display messages written in a Latin type alphabet.
